RESUMEN
Tuberculosis of the central nervous system is a major cause of morbidity and mortality in developing nations where it accounts for 10 to 30% of intracranial space-occupying lesions. It preferentially affects young subjects, predominantly male. MRI and in particular new methods, including magnetization transfer and diffusion-weighted imaging, are useful for positive and differential diagnoses of central nervous system tuberculosis and surveillance during treatment.

Rhinoscleroma is a rare chronic granulomatous infection caused by Klebsiella rhinoscleromatis. Because of its mundane clinical presentation as chronic rhinits, it is frequently unrecognized. The authors report the cases of two female patients with pseudotumoral rhiniscleromas located in the septum and in the rhinopharynx respectively CT scan permitted a precise evaluation of the extent of the lesion. Among the various para-clinical examinations required, bacteriological studies are very important and should be performed comcomitantly with biopsy.

Gastrointestinal bleeding secondary to a rupture of an aneurysm of the hepatic artery is rare. We report a case of an 81-year-old man, who was admitted with hematemesis and melena. Gastroduodenoscopy revealed an abundant bleeding from the posterior wall of the duodenal bulb. CT-scan shoved an aneurysm arising from the hepatic artery. Ultrasound, computed tomography and angiography are the methods of choice for gastrointestinal bleeding diagnosis if endoscopy is inconclusive.
