Case report: Infectious cerebral vasculitis due to rickettsiosis.

Rickettsiosis is a widespread infection throughout the world and in Africa, it covers a wide range of infectious diseases caused by Rickettsia species. Rickettsial infections, with the exception of Q fever, typically present with fever, rash, and vasculitis.

A ruptured renal lymphangiectasia in the retroperitoneum: A rare complication of a rare condition.

Renal lymphangiectasia is a rare and benign renal lymphatics disorder. It is usually asymptomatic, and rarely revealed by lumbar pain, arterial hypertension or retroperitoneal fluid collection. Radiological diagnostic is challenging and can be done if radiologists are aware of the imaging findings.

Spinal cord infarction complicating acute aortic syndrome: about 2 cases.

Mediastinal bronchial artery aneurysm presenting as an incidental mediastinal mass: A rare finding.

Mediastinal bronchial artery aneurysm is very rare and only few cases have been reported in the literature. The clinical presentations are varied, ranging from an incidental radiological finding to a cataclysmic rupture leading to hemorrhagic shock. Thus, a quick treatment is indicated upon diagnosis.

[Idiopathic sclerosing encapsulating peritonitis: a case report].

Sclerosing encapsulating peritonitis is a very rare pathological entity. It is a chronic fibroinflammatory disease affecting the peritoneum and leading to the formation of diffuse egg-shell-shaped fibrous capsule which totally or locally encapsulate the abdominal viscera, in particular the digestive tract. Clinical signs are little specific and misleading.
