Central nervous system lesions associated with Crohn's disease.

Central nervous system vasculitis is an exceptional extraintestinal manifestation of Crohn's disease. Reported here are 2 cases, highlighting the difficulty of differential-diagnosis with multiple sclerosis and stressing the importance of early immuno-suppressive therapy.

An atypical infectious complication of anterior cervical surgery.

We report a 44-year-old woman who developed an atypical retro-oesophageal abscess 4 years after anterior cervical surgery with fusion (ACSF). She presented with dysphagia but no fever or definite laboratory signs of inflammation. Delayed or chronic dysphagia following Cloward's operation is usually related to graft displacement.

Prognostic value positron emission tomography with [18F]fluoro-2-deoxy-D-glucose in the low-grade glioma.

Objective: The natural history of the supratentorial low-grade glioma (LGG) of the adult is variable, and its malignant transformation is hardly predictable. Because positron emission tomography with [18F]fluoro-2-deoxy-D-glucose (FDG) has prognostic value in high-grade gliomas, this study was designed to search for a possible relationship between glucose metabolism and risk of malignant evolution in LGGs.

Methods: Positron emission tomography with FDG was performed in 28 patients with LGGs (22 at the time of diagnosis and 6 after the diagnosis).

[Cerebral metastases of gynecological origin].

Background: A few cases of brain metastasis from gynecological cancer have been reported. This tumor usually dissaminates via the blood stream, normally through surface implantation or lymphatic spread.

Purpose: We report four cases of brain metastases from gynecological cancer (2 from ovarian cancer and 2 from endometrial cancer).
