Intracranial meningiomas are benign extra-axial brain tumors. Their etiology is undetermined and several hypotheses have been proposed to explain their genesis. The clinical symptomatology of intracranial meningiomas is atypical and varies according to the location of the lesion, its size, and its relationship with neighboring organs. Imaging is essential for establishing a positive diagnosis, but the way to a diagnosis of certainty remains histological. In this article, we describe the CT and magnetic resonance imaging aspects of an intraosseous meningioma discovered in a patient in her forties that presented with right proptosis, and whose brain MRI revealed a cranial lesion with adjacent meningeal involvement; the CT scan subsequently performed allowed a better analysis of the bone lesion, the appearance of which suggested an intraosseous meningioma. This diagnosis was confirmed by a histological exam. The purpose of this article is to illustrate the CT and MRI aspects of this entity by reporting a case of intraosseous meningioma of spheno-orbital location.

In Morocco, envenomations caused by viper bites and scorpion stings are frequent and associated with high lethality. It occurs mainly during the summer season with a peak between June and August. It is a medical emergency requiring intensive care. It is a life-threatening disease mainly due to the systemic hemorrhagic syndrome. Here, we present the clinical course of a patient in his 50s who suffered a snakebite and describe the neurological sequelae. The patient was admitted to the emergency room in a state of unconsciousness with gangrene on the right foot. An emergency brain scan showed meningeal hemorrhage and intracerebral hematomas. The biological assessment revealed disseminated intravascular coagulation. The evolution of the clinical course was rapidly unfavorable and the patient died within 24 hours of admission.

Ureteral hematoma is a rare complication occurring during anticoagulant therapy, with fewer than 10 cases reported in the literature. Bleeding complications are underestimated. They affect about 10% of patients treated with long-term anti-vitamin K (AVK). The appearance of macroscopic hematuria may indicate the presence of underlying organic damage. Clinically, ureteral hematoma is manifested by lumbar or abdominal pain often associated with macroscopic hematuria. Imaging plays a major role in its diagnosis. Clinical and radiological evolution is always rapidly favorable after the correction of coagulation disorders and the immediate discontinuation of anticoagulant treatment. We report in this work the case of a patient in her 50s who presented a ureteral hematoma during her anticoagulant treatment.
