[Technical and functional aspects of catheterization of inferior petrosal sinuses in ACTH dependent Cushing's syndrome].

Objective: To describe and analyze technique for bilateral catheterization of inferior petrosal sinus in our service, discussing the difficulties and success rates found.

Subjects And Methods: Fourteen patients with suspected Cushing's syndrome underwent bilateral inferior petrosal sinuses (IPS) catheterization between 2009 and 2012. The technique for catheterization and for hormone analysis were described.

A rare association of tension pneumocephalus and a large frontoethmoidal osteoma: imaging features and surgical treatment.

Osteomas are the most common benign paranasal sinus tumors and are often found in the frontal and ethmoidal sinus. Intracranial complications such as pneumocephalus have occasionally been reported in association with osteomas. We describe a 33-year-old man with a large frontoethmoidal osteoma complicated by tension pneumocephalus and neurological disturbances, and we discuss the clinical and imaging resolutions after surgical management.

Endoscopic endonasal transsphenoidal approach for pituitary adenomas: technical aspects and report of casuistic.

Objective: Analyse technical aspects, effectiveness and morbidity of the endoscopic endonasal transphenoidal approach for pituitary adenomas.

Method: From January 2005 to September 2008, 30 consecutive patients underwent endoscopic endonasal resection of pituitary adenomas with a follow up from 3 to 36 months. Their medical charts were retrospectively analysed.

Splenosis. A diagnosis to be considered.

The term splenosis applies to the autotransplanted splenic tissue resulting from seeding in the context of past splenic trauma or surgery. We report a 42-year-old man with a history of splenectomy observed for an incidentally found retrovesical mass thought to be an ectopic testicle. The abdominal laparotomy revealed multiple focuses of pelvic splenosis.
