[Rare digestive tumors: gastrointestinal stromal tumors (GISTs): about a case of small bowel location and literature review]. / Tumeurs digestives rares: tumeur gastro-intestinale stromale (GIST): à propos d'un cas de localisation grêlique et revue de littérature.

Gastrointestinal stromal tumors (GISTs) are a rare group of mesenchymal tumors mainly occurring in the gastrointestinal tract. Previously, GISTs were classified as smooth muscle tumors also known as leiomyomas, leiomyosarcomas or leiomyoblastomas. However, since the advent of immunohistochemistry, GISTs have been diagnosed on the basis of the identification of c-kit-positive cells. We here report a case of stromal tumor of the small intestine in order to analyze it in the light of literature data and imaging results, which may suggest prebiopsy diagnosis as well as its therapeutic and prognostic peculiarities.

Giant bilateral angiomyolipomas with spontaneous hemorrhage and inferior vena cava thrombosis in a patient with tuberous sclerosis.

Renal angiomyolipomas are rare type of benign renal neoplasm. They are composed of vascular, smooth and fat elements and can be associated to phacomatosis as Tuberous Sclerosis disease. Symptomatic presentation is most frequently spontaneous retroperitoneal hemorrhage, which can be fatal. The risk of bleeding is proportional to the size of the lesion (>4 cm of diameter). Typical angiomyolipomas are benign but may have alarming properties: nuclear pleomorphism and mitotic activity, extension into the vena cava, and spread to regional lymph nodes without malignant progression. We report a Computed Tomography finding of a rare giant bilateral angiomyolipomas with spontaneous hemorrhage and inferior vena cava thrombus in a patient with tuberous sclerosis, emphasizing the importance of imagery in the positive and etiologic diagnosis.

[Giant congenital intrapericardial left atrial appendage aneurysm: about a case and review of the literature]. / Anévrysme congénital géant intra péricardique de l'auricule gauche: à propos d'un cas avec revue de la littérature.

Left atrial appendage aneurysm is a very rare heart anomaly. It may be congenital or acquired, secondary to inflammatory or degenerative processes. Most cases are asymptomatic. The prevalence of these lesions in pediatric age has been very rarely reported. As it can cause potentially fatal arrhythmias or thrombus, surgery is required immediately after diagnosis. This study reports the case of a 14-year-old boy with rapidly progressive dyspnea, palpitations, sensation of repetitive dizziness and fainting, in whom congenital left atrial appendage aneurysm was detected. Diagnosis was based on coronary CTA data. The patient was successfully treated with surgical resection of the aneurysm.

[Myositis ossificans circumscripta, an unusual location: about a case and review of the literature]. / La myosite ossifiante circonscrite, une localisation inhabituelle - à propos d'un cas et revue de la littérature.

Myositis ossificans circumscripta (MOC) is a rare condition characterized by nontumoral heterotopic ossification of the soft tissues. This condition affects young subjects, occurring mainly after trauma. It is ubiquitous, predominantly located in girdles and limbs. We report the case of a young patient with paravertebral MOC without traumatic context; the aim of this study was to recall diagnostic criteria and imaging aspects.

[Scimitar syndrome: about a case and review of the literature]. / Syndrome de cimeterre: à propos d'un cas et revue de la literature.

Scimitar syndrome or veino-lobaire syndrome (term coined by Felson) is a very rare disease characterized by the combination of cardiopulmonary anomalies, in particular an anomalous right pulmonary venous return, located mostly in the inferior vena cava. We here report the original case of a 6-month-old female infant presenting with acute dyspnea. The diagnosis was suspected on the basis of thoracic radiograph and was confirmed by tomodensitometry which showed a large single right pulmonary vein draining into the right atrium associated with dextrocardia and pulmonary sequestration. The prognosis was based on the size of the left-right shunt and related malformations.

Dual intersection syndrome of the forearm: a case report.

The intersection syndrome, described since the 19(th) century, is an uncommon disorder associated with rubbing at the crossing point between the first dorsal compartment muscles and the radial wrist extensor muscles. Imaging modalities used to diagnosis this syndrome includes ultrasonography and magnetic resonance imaging. We reported a case of a 60-year-old man presented to our formation with painful swelling on the dorsum of the wrist and forearm. An MRI and an ultrasound were performed, and objectified a dual cross syndrome of the forearm.

Hemiparesis post cerebral malaria.

Cerebral malaria is one of the most serious complications in the Plasmodium falciparum infection. In endemic areas, the cerebral malaria interested mainly children. The occurrence in adults is very rare and most interested adult traveling in tropical zones. This case report describes a motor deficit post cerebral malaria in a young adult traveling in malaria endemic area. This complication has been reported especially in children and seems very rare in adults.
