[A case of an acute pancreatitis after endoscopic band ligation of esophageal varices: a strong association or an unusual complication?]. / Pancréatite aiguë au décours d'une séance de ligature elastique de varices oesophagiennes: une association fortuite ou une complication inhabituelle?

BACKGROUND: Endoscopic band ligation is considered as the gold standard of treatment for oesophageal varices. Fewer and often mild complications can occur. AIM: To report and to discuss an association between oesophageal variceal endoscopic band ligation and actue pancreatitis. CASE REPORT: We report the original case of a patient with cirrhosis and who had presented an acute pancreatitis 3 days after oesophageal variceal endoscopic band ligation. Common aetiologies of acute pancreatitis was eliminated. The evolution was favourable without specific treatment. CONCLUSION: In the absence of similar case reports, the association between oesophageal variceal endoscopic band ligation and acute pancreatitis observed in our patient remains rather fortuitous even though experimental studies can explain these association.

[Value of magnetic resonance imaging in central nervous system tuberculosis]. / Apport de l'IRM dans le diagnostic de la tuberculose du système nerveux central.

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.

Percutaneous drainage of suppurative pylephlebitis complicating acute pancreatitis.

Suppurative pylephlebitis is a rare condition with a significant mortality rate, ranging from 50% to 80%. We report a case of suppurative pylephlebitis complicating acute pancreatitis treated by percutaneous drainage in a 40-year-old woman. The patient had an uneventful recovery.

Atypical small hemangiomas of the liver: hypervascular hemangiomas.

Hyperdynamic hemangiomas (HH) are atypical hepatic hemangiomas with an incidence of approximately 16% of all hemangiomas in the liver. We report a case of HH in a 47-year-old woman. Multiphase helical CT scan, MRI appearances and differential diagnoses are discussed.

[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.
