High grade Burkitt lymphoma in an immunocompetent young patient: Concomitant gastric and ileal localizations.

Burkitt lymphoma is a highly aggressive and rapidly growing B cell non-Hodgkin lymphoma with heterogeneous pattern of manifestations. We present a rare case of a 39-year-old immunocompetent male with double localization of Burkitt lymphoma: gastroduodenal and ileal tract. The gastric location is extremely rare, and the association with another site is unusual with only few reports in the literature. Imaging modalities play a crucial role in correct diagnosis as it can manifest as a focal mass or as segmental wall thickening. Radiologists should recognize common and uncommon presentations and sites of Burkitt lymphoma given the urgency of potential treatment, in order to improve the patient's prognosis.

Intrahepatic abscess secondary to retained stercolith, following laparoscopic appendectomy.

Abscesses of the peritoneal cavity and in particular hepatic abscess due to stercolith retention are a rare complication of appendectomy. Their prevalence is likely to increase as laparoscopic appendectomies become more common. This potentially serious complication can be prevented by following certain technical recommendations. Percutaneous drainage is bound to failure since it leaves the coprolite that causes the recurrence of the abscess, thus when it happens it requires surgical drainage. We report a case of a 40-year-old man, who underwent laparoscopic appendectomy 8 months prior, and presented to the emergency department for acute pain of the right hypochondrium. The radiologic investigations revealed 2 abscesses of the liver and the right iliac fossa containing a central spontaneously hyperdense stercolith. The patient was treated with open surgery removing the stercoliths and draining of the abscesses, with favorable postoperative outcome.

Central nervous system tuberculosis in immunocompetent patients: Two case reports with literature review.

Central nervous system tuberculosis (CNS) is a rare but extremely dangerous condition that has been reported in 5%-10% of extrapulmonary tuberculosis cases and accounts for approximately 1% of all tuberculosis cases. We present 2 cases of isolated central system tuberculosis in immunocompetent patients: a 57-year-old female and a 22-year-old young man, both of whom had MRI findings consistent with meningitis and tuberculomas and were complicated by cerebral ischemic infarction in the second case. Despite delaying therapy, both patients who had positive TB tests (PCR and QuantiFERON-TB Gold) nevertheless demonstrated clinical improvement. Although central nervous system tuberculosis has a high mortality rate and a high level of neurological morbidity, diagnosing it remains difficult because clinical symptoms and radiological findings can mimic other conditions such as pyogenic abscess, toxoplasmosis, sarcoidosis, and malignancy.

Not to be confused, this is a pleural fibroma: Case report and literature review.

Solitary fibrous tumors of the pleura are rare mesenchymal tumors. The diagnosis is often made incidentally. We report the case of 65 year old patient consulting for dry cough evolving for 1 year. The clinical examination revealed a mattness of the right hemi thorax. The chest X-ray detected a right lower lobar opacity. The CT scan showed a right lateral basal mass, connected at an obtuse angle with the wall. A CTguided biopsy with an anatomopathological and immunohistochemical examination were performed, thus confirming the diagnosis of a solitary fibrous pleural tumor. The evolution after treatment was favorable. Complete surgical resection of the tumor is usually sufficient, but there are reported cases with recurrence.

Primary peritoneal hydatid cyst with gastric fistula complicated by spontaneous pleural and bronchial fistula: report of a rare observation.

Hydatid cyst is a parasitic infection widespread in Morocco. Hydatid disease mainly affects the lungs and liver. Primary peritoneal hydatidosis has a stealth clinical evolution until it reaches complicated stages. Complications may include mass effect, rupture, allergic reactions and secondary infection. We report a very rare case of an isolated primary peritoneal hydatid cyst, first complicated by a gastric fistula and secondarily by a spontaneous pleural and bronchial fistula in a patient, who presented with isolated upper abdominal pain.

Primary muscular hydadit cyst: Case report.

Primary hydatid disease of the skeletal muscle without systemic involvement is rare. Since the infection appears on clinical examination to be a soft-tissue tumor. It is important to have a preoperative radiological evaluation, particularly with magnetic resonance imaging (MRI) to avoid biopsy or improper cyst management during surgery. We present a unique case of a primary hydatid cyst manifesting as an expanding soft-tissue mass in a 31-year-old woman's left thigh with magnetic resonance imaging revealed a very suggestive aspect of hydatid cyst in the adductor muscles and shows the interaction between cysts and nearby structures. The cyst was surgically removed, and macroscopic and microscopic histopathological examinations confirmed the diagnosis of muscular hydatidosis.

Multifocal extramedullary hematopoiesis in a 15-year-old girl with beta thalassemia: A case report.

Extramedullary hematopoiesis is a rare disorder in which hematopoietic cells proliferate in tissues other than the bone marrow as a result of a range of hematologic illnesses. Our case is unique in that it covers a number of extramedullary hematopoiesis sites in a 15-year-old girl, some of which are uncommon.

Primary umbilical endometriosis: case report and literature review of an unusual cause of catamenial umbilical pain.

Endometriosis is defined by the presence of functional ectopic endometrial tissue outside the uterine cavity, excluding the myometrium. It is a benign tumor that can infiltrate and cling to other organs, mimicking a malignant tumor. Umbilical endometriosis is a rare type of endometriosis that can occur naturally or as a result of a surgical operation. We report the case of a patient who experienced catamenial umbilical discomfort and whose radiological examination revealed endometriotic involvement.

Acute Intestinal Intussusception: Beware of Burkitt's Lymphoma.

Burkitt's lymphoma can show in a variety of ways, and it's frequently identified in children owing to the development of an abdominal tumor. This aggressive, fast growing tumor can induce either indirect symptoms due to pressure phenomena or direct involvement of the intestine lumen, resulting in intestinal obstruction or intussusception. We are reporting a case of intestinal intussusception in a patient with Burkitt's lymphoma.

Achilles swelling and ataxia in an adolescent: A case report of cerebrotendinous xanthomatosis.

Cerebrotendinous xanthomatosis (CTX) is a rare hereditary disease characterized by a bile acid metabolic problem that causes cholesterol metabolites to accumulate in various organs. There are 2 types of CTX: traditional and spinal. The imaging characteristics are usual and allow for diagnosis confirmation. The brain's magnetic resonance imaging (MRI) reveals bilateral dentate nucleus lesions as well as modest white matter abnormalities. Tendon xanthomas (typically in the Achilles tendons on both sides) are a common finding. Cerebrotendinous xanthomatosis is a multidisciplinary diagnosis that must be made early to avoid neurologic injury and worsening. We show a CTX instance that has typical imaging and biology features.
