Cystic meningioma: A case report with a literature review

Cystic meningiomas are very rare tumors of the central nervous system. We report the case of a 62-year-old female how presented headaches resistant to usual analgesics with behavior disorders. Cerebral CT scan showed a right frontal extra-axial tumor with firm and cystic component, brain MRI evoked the diagnosis, surgery removed the entire tumor and histological examination confirmed it. A cystic meningioma should not be omitted from the differential diagnosis of brain tumors with a cystic component and which clinical, radiological, histological and therapeutic features are discussed.     

Transient ischemic attack due to multiple spontaneous calcified embolus of the cerebral arteries on a calcified mitral and aortic stenosis

We report a case of calcified mitral and aortic stenosis revealed by a reversible ischemic stroke. A 59-year-old male patient, with background of hypertension, kidney failure, diabetes, and dyslipidemia, presented with neither acute onset of right-sided hemiparesis without aphasia nor any loss of consciousness. Head computed tomography (CT) revealed multiple rounded and amorph calcified high-density calcifications within the distal segments of both sylvian and posterior cerebral arteries. Angiographic CT of the carotids didn''t reveal any stenosis or atherosclerotic plaques. Thoracic CT showed massive mitral and aortic valvular calcifications with a left ventricular hypertrophy.     

Severe hypercalcemia complicated by acute pancreatitis revealing generalized bone lysis metastasis: Case report and review

Malignant hypercalcemia is a frequent metabolic complication of osteophilic tumors, exceptionally revealing cavitary cancer, but its prognosis remains poor despite early and adequate management. We report the case of a young patient, smoker without any previous history, admitted for the management of a digestive symptoms made of abdominal pain with food vomiting. The patient had an electrocardiogram withchest computed tomography scan and BBC evoking PA on malignant hypercalcemia. An etiological investigation was conducted to confirm the tumoral origin of the hypercalcemia. We put the patient on hyperhydration with corticotherapie and biohosphonates with a good clinical and biological improvement. Malignant hypercalcemia affects about 10%-20% of patients with cancer including nasopharyngeal carcinoma. Its clinical presentation varies according to the extent and speed of onset, responsible for multivisceral involvement including kidney, heart, neuropsychiatric system, which may engage the patient''s vital prognosis. The therapeutic management is based on 4 main principles; hyperhydration, increase of urinary calcium excretion by loop diuretics, decrease of bone resorption by biphosphonates and extrarenal purification which remains the ideal choice in case of life-threatening severe hypercalcemia. Acute hypercalcemic pancreatitis as a mode of revelation of cavum cancer has almost never been described in the literature     

Reversible splenial lesion syndrome (RESLES): Two patients as study cases

Reversible splenial injury syndrome (RESLES) is a rare clinicoradiological entity that defines a reversible lesion in the splenium of the callosum in magnetic resonance imaging.RESLES may be of infectious iatrogenic or metabolic origin. We report 2 cases of drug induced RESLES in our training.The presence of an isolated lesion of the corpus callosum in a context of polymedication by psychotropic drugs and the regression in less than 4 weeks suggests a toxic origin, in particular medicinal.The pathophysiology of these reversibles lesions of the splenium of callosum is not very clear, most often it is a phenomenon of vasogenic edema that is evoked, the clinical symptoms are very varied and nonspecific, and the prognosis is generally good in the absence of underlying disorder.     

Atypical esophageal granular cell tumor: Case report

Esophageal granular cell tumors (GCTs), or also called Abrikossoff''s tumor are rare benign tumors originating from Schwann cells most commonly found in the skin, subcutaneous tissue, and tongue. Approximately 5% –8% arise in the gastrointestinal tract, and one-third of these tumors arise in the esophagus [1]. This neoplasm has a benign behavior usually, but there have been described a malignant transformation in 2% –3% of the cases. Herein, we discuss a case of a 70-year-old male patient with no pathological background, admitted for dysphagia evolving in 3 months that was explored with endoscopy and CT, the diagnosis at this level was challenging but the histopathology and Immunohistochemistry confirmed the presence of granular cells thus confirm the diagnosis.The purpose of our work is to report the uncommon evolution of an Abrikossoff ‘s tumor located in the esophagus, as a warning of the possible malignant transformation of this tumor mostly benign; also we made a review of the literature.     

Diffuse malignant peritoneal mesothelioma mimicking ovarian cancer.

Diffuse malignant peritoneal mesothelioma (DMPM) and peritoneal carcinomatosis have similar computed tomography imaging features. Peritoneal carcinomatosis is a known metastatic site for many malignancies and particularly gastrointestinal tract and ovarian cancers. Also, DMPM can masquerade as an ovarian epithelial neoplasm, with very similar clinical presentation and an overlap in imaging findings. When no evident primary tumor is detected other than the peritoneal disease, primary malignant mesothelioma should be considered. Since accurate diagnosis is essential for treatment management, the gold standard in differentiating between these two entities lies in histological analysis. We report a case of DMPM that was initially misdiagnosed as an ovarian cancer, where the biopsy of a peritoneal nodule was able to correct and confirm the diagnosis of DMPM.
