Introduction: Xanthogranulomas are rare, benign, usually asymptomatic, cutaneous tumors most frequently seen in children (juvenile xanthogranulomas). Some lesions can be found accidentally at randomly performed cerebral computer tomography (CT) or magnetic resonance imaging (MRI) or even on autopsy.
Case report: We present the case of a 44 year-old woman, known with a thrombophilic disorder (PAI-1 gene mutation, MTHFR C677T and A1298C) on chronic anticoagulant treatment. The onset of symptoms was in 2010, when she presented paresthesia and lower limbs weakness. Two years later the patient presents with severe intermittent headache and left hemicrania and a cerebral angio-MRI is performed showing a left postero-inferior cerebellar artery aneurysm and two choroid plexus intraventricular masses in the lateral ventricles. The patient developed a new symptom, dysarthria in 2014 and in 2015 has multiple episodes of loss of consciousness, interpreted as epileptic seizures. Routine blood tests were within normal range, except for a high cholesterol level. The patient was tested for autoimmune, infectious, endocrine and metabolic diseases that were negative. Surgical treatment and biopsy from the lesion was proposed, however the patient refused both procedures.
Conclusions: There is an association between xanthogranulomas localization and the choroid plexus, the most frequent CNS origin being in the trigon of the lateral ventricle. Our case does not resemble with any other case published, mostly because the unusual presentation, symptomatology and the association between xanthogranulomas, thrombophilia and postero-inferior cerebellar artery aneurysm which were never reported before in other cases of xanthogranulomas from the literature.

Introduction: Hyperechoic liver lesions identified by conventional ultrasonography are diverse in underlying pathology and most of the time require further investigations. Gastrointestinal stromal tumors (GIST) are rare neoplasms of the gastrointestinal tract which are uncommonly found in metastatic stages at first presentation.
Case report: We present the case of a 51 years old woman with nonspecific symptoms in which conventional ultrasonography showed hyperechoic lesions in the right lobe of the liver with a diameter up to 40 mm. Esophagogastroduodenoscopy revealed a submucosal tumor on the small curvature of the stomach, on the anterior wall, with central ulceration, with normal narrow band imaging (NBI) mucosal pattern and negative gastric biopsy. Contrast enhanced ultrasonography was performed, describing multiple lesions with inhomogeneous enhancement in the arterial phase and rapid washout at the end of arterial phase. Endoscopic ultrasound with fine needle aspiration (EUS-FNA) biopsy examination was definitive for the final diagnosis of epithelioid gastric gastrointestinal stromal tumor. The patient was diagnosed with T2N0M1 epithelioid gastric GIST, stage IV, and is currently under treatment with tyrosine kinase inhibitors.
Conclusions: GIST represent a diagnostic challenge in medical practice because of its size, unusual location in the submucosal layer and lack of symptoms. The role of EUS-FNA is of paramount importance in increasing the accuracy of diagnosis in the case of GIST. The particularity in our case consists of the unusual presentation with the lack of specific symptoms and signs associated with the presence of metastatic lesions at the moment of the diagnosis of GIST.

Introduction. The encapsulated, non-invasive subtype of follicular variant of papillary thyroid carcinoma (FVPTC) represents approximately 10% to 20% of all thyroid cancers. Many studies over the past decade have shown that these tumors carry an indolent clinical course, with no recurrence, even in patients treated by lobectomy. Their reclassification as neoplasms with “very low malignant potential” has recently been suggested by an international group of experts and a new terminology was proposed: “non-invasive follicular thyroid neoplasm with papillary-like nuclear features” (NIFTP). However, a diagnosis of NIFTP is still challenging for many pathologists in daily practice.
Presentation of case series. By presenting six illustrative cases of NIFTP, this article aims to highlight the diagnostic criteria and the burden difficulties when dealing with NIFTP cases. Characteristic histological features, inclusion and exclusion criteria for NIFTP, as well as sampling guidelines and differential diagnosis challenges are all discussed.
Conclusions. The diagnosis of NIFTP is not straightforward and requires meeting strict inclusion and exclusion criteria. Total sampling of the tumor capsule in these cases is mandatory in order to exclude invasion (capsular and/or vascular). A diagnosis of NIFTP promotes a less-aggressive patient management that is, no need for completion thyroidectomy or radioactive iodine therapy.

Introduction: Glomus tumors are rare benign mesenchymal neoplasms accounting for only 2% of all types of soft tissue tumors. Commonly located in the peripheral soft tissues, they are most frequently encountered in the subungual areas of fingers and toes, and very rarely in visceral organs due to the absence of glomus bodies. To date, 22 cases of primary renal glomus tumors have been described in the literature, of which 17 benign, with no evidence of recurrence or metastasis, three cases of malignant glomus tumor, and two cases with uncertain malignant potential.
Case report: We report the 18th case of a benign glomus tumor of the kidney in a 49-year-old female patient, presenting the microscopic appearance (round, uniform cells with indistinct borders, scant finely granular eosinophilic cytoplasm, round nuclei lacking prominent nucleoli, arranged in solid sheets, accompanied by slit-like vascular spaces), the immunohistochemical profile (tumor cells showed immunoreactivity for smooth muscle actin, vimentin, as well as for CD34; they were negative for AE1/AE3, desmin, HMB-45, S-100 protein, renin, and chromogranin), and the differential diagnosis of this rare entity (juxtaglomerular tumor, angiomyolipoma, hemangioma, epithelioid leyomioma, solitary fibrous tumor, carcinoid tumor, and paraganglioma).
Conclusion: Primary renal glomus tumors are rare tumors that radiologically can mimic other mesenchymal renal neoplasm. Accurate diagnosis is based on the microscopic appearance and especially the characteristic immunophenotype.

Tay-Sachs disease (TSD) is a rare, inherited, autosomal rececessive lysosomal storage disease. The late-onset form is an uncommon condition among non-Jewish population.
We present the case of a 32 years old male patient without Jewish origins, in whom the disease began in adolescence and was initially diagnosed with spinal muscular atrophy. He developed progressively protean neurological symptomatology, including tetraparesis, cerebellar and extrapyramidal syndromes. The diagnosis was based on the cerebral MRI, showing severe cerebellar atrophy and the determination of the Hexosaminidase A activity, revealing low level.
In patients showing signs of lower motor neuron involvement, cerebellar and pyramidal signs and marked cerebellar atrophy the late-onset TSD should be suspected, and the first step in establishing the diagnosis should be to determine the serum activity of Hexosaminidase A.

Introduction: Colorectal cancer is one of the most common types of malignant tumors worldwide. In patients with situs abnormalities such as situs inversus totalis or situs ambiguus, the presence of this tumor could be a challenge for the surgeon, especially in cases in which the laparoscopic approach is considered.
Case presentation: We report the case of a 69-year-old male patient with situs inversus totalis. This particular case of situs inversus totalis was not a classical type because the patient had bilateral bilobed lungs, polysplenia, preduodenal portal vein in association with midgut malrotation. The pathology report after surgery revealed moderately differentiated adenocarcinoma of the sigmoid colon, stage pT3 N1c M1a, liver metastases but without metastases in the eight resected lymph nodes. We compared this rare association of diseases of particular anatomic aspects with other reports in the specialty literature.
Conclusion: The identification of situs abnormalities or other malformations in patients with resectable colorectal cancer is essential, thus preoperative imaging studies are imperative for a proper surgical management. Colorectal cancer metastasizing patterns in patients with intestinal malrotation need to be further investigated.

Introduction: Extrahepatic portal vein thrombosis (EPVT) is the most frequent cause that leads to portal hypertension in non-cirrhotic patients. This condition is related to systemic and local risk factors (such as inflammatory lesions, injuries to portal venous system by surgery, vascular procedures).
Case presentation: A case of extended extrahepatic portal vein thrombosis and simultaneous thrombosis of left common iliac vein and inferior vena cava, appeared after abdominal surgery in a hypertensive, diabetic, 50 y.o. man is presented. An acute episode of abdominal pain was interpreted as an emergency and a surgical (initially laparoscopic and then open) procedure was planned in order to perform an appendectomy. Discharge diagnosis was hemoperitoneum secondary to iatrogenic rupture of sigmoid mesocolon provoked by trocar manipulation. Repeated imaging studies performed later revealed the thrombosis of portal vein with extension into right portal branch associated with superior mesenteric thrombosis and free-floating thrombus into left common iliac vein extended towards inferior vena cava. Surgical manoeuvres are considered as triggers of these thrombotic events. After 4 weeks of parenteral anticoagulation a partial recanalization of thrombi was identified, without bleedings.
Conclusions: Acute EPVT needs a carefully management. Case is linked to abdominal surgery and requires prolonged anticoagulation related to simultaneous portal and iliac vein thrombosis. Associated conditions (hypertension and diabetes mellitus) must have an appropriate approach. After our knowledge this is the first case published in literature.

Introduction: Isolated Short Stature Homeobox (SHOX) gene haploinsufficiency can be found in 2-15% of individuals diagnosed with idiopathic short stature determining different skeletal phenotypes.
Case presentation: We present the history of an 11-year-old female patient diagnosed with idiopathic short stature. Clinically, she was moderately disproportionate, with cubitus valgus and palatum ogivale. Her breast development was in Tanner stage 1 at the time of diagnosis. The endocrine diagnostic tests did not reveal any abnormalities except a slightly elevated thyroid stimulating hormone. We have also assessed the bone radiological findings. Multiplex Ligation-dependent Probe Amplification technique used for the identification of SHOX gene haploinsufficiency showed a heterozygous deletion spanning exons 4-5 of SHOX gene.
Conclusions: This case is determined by deletions in exons 4-5 of SHOX gene and indicates the necessity of screening for SHOX deletions in patients diagnosed with idiopathic short stature, especially in children having increased sitting height-to-height ratio or decreased extremities-to-trunk ratio.

In type A aortic dissection (AoD) an early and accurate diagnosis is essential to improve survival, by applying urgent surgical repair. 3D transthoracic echocardiography (3D-TTE), an advanced noninvasive imaging technique, could offer a comprehensive evaluation of the ascending aorta and aortic arch in this regard. Both modalities of real-time 3D imaging – live 3D and full-volume aquisition – proved to be useful in evaluating the localization and extent of AoD. Our case illustrates the utility of 3D-TTE in the complex assessment AoD. By providing the proper anatomical dataset, 3D-TTE could facilitate considerably the diagnosis of type A AoD.

Introduction: The imaging method of cone beam is an improved, extremely accurate computed tomography applicable in the whole field of dentistry. Due to its ability to locate the exact position of the impacted teeth, CBCT software has an important role in the management of difficult cases of impacted third molar. In some situations, the lower third molar is quite near to the inferior alveolar nerve that the surgical extraction can present a high risk of post-operative sensitive impairs of the skin and mucosa of the lower lip and chin on the same side.
Presentation of case series: Our study tried to assess the contribution of CBCT in the pre-operative evaluation and further treatment of patients with impacted third molars in mandibular bone with high risk of inferior alveolar nerve injury. The paper presents three clinical cases showing positive signs on standard OPG, which exhibit indicators of a potential contact between the inferior alveolar nerve and the impacted lower third molars. For an improved exploration Dental CT Scan, DICOM image acquisition program, and 3D reconstruction with a special software were used. Conclusions: The study showed that compared with panoramic radiography, CBCT improve the evaluation of the surgical risk and allow a more accurate planning of surgery.
