[Rupture of hydatid cyst of the liver into the duodenum. A case report]. / Kyste hydatique du foie rompu dans le duodénum. A propos d'un cas.

BACKGROUND: Rupture of hydatid cyst in the digestive tract is a rare complication even in endemic areas. AIM: Authors report a case of a hydatid cyst of the left hepatic lobe ruptured in the duodenum CASE: was discovered at the occasion of epigastric pain and vomiting. Ct-scan revealed presence of air in a calcified hydatid cyst of the left liver lobe and a fistulous tract between the cyst and the duodenum. Endoscopy confirmed the diagnosis by the visualisation of a fistulous orifice of the anterior aspect of the first duodenum with a protrusion of hydatid membrane. Patient was treated surgically and had a partial cysto-pericystectomy and suture of duodenum.

Fibrolipoma of the median nerve.

Neural fibrolipoma or fibrolipomatous hamartoma is an uncommon benign tumor that usually arises in the median nerve. Fibrofatty tissue proliferates around the nerve and infiltrates the epineurium and perineurium. We report a case of fibrolipomatous hamartoma of the left median nerve in an 18-year-old woman. Our objective was to describe the pathognomonic magnetic resonance imaging features, whose presence obviates the need for a diagnostic biopsy.

[MRI findings in pituitary-hypothalamic axis Langerhans cell histiocytosis]. / Apport de l'IRM dans le diagnostic de l'histiocytose langerhansienne hypothalamo-pituitaire.

Pituitary-hypothalamic axis Langerhans cell histiocytosis is an uncommon entity. It is a rare disease in adults. The CT and MR study provides us the best anatomo-topographic evaluation and determine the precise size of the lesion which are necessary to the treatment. We report a case of hypothalamic involvement by Langerhans cell histiocytosis accompanied by lesions in bone affecting a 31-year-old woman. The clinical, histiotological and CT/MR findings of histiocytosis X are described in this article.
