Microsurgical management of aneurysms of the superior cerebellar artery - lessons learnt: An experience of 14 consecutive cases and review of the literature.

Objective: This is a retrospective study from January 2002 to December 2012 analyzing the results of microsurgical clipping for aneurysms arising from the superior cerebellar artery (SCA).

Materials And Methods: All patients with SCA were evaluated with computerized tomography angiography and/or digital subtraction angiography (DSA) prior to surgery. All patients in our series underwent microsurgical clipping and postoperative DSA to assess the extent of aneurysm occlusion.

Extradural temporopolar approach for parahypothalamic hypothalamic hamartoma and use of posterior communicating artery as resection margin pointer.

Background: Hypothalamic hamartomas (HH) are malformations originating from the hypothalamus and are associated with seizures, hormonal and behavioral abnormalities.

Method: Most patients, especially those with a typical syndrome characterized by gelastic seizures, precocious puberty, cognitive decline, and behavior problems, are diagnosed in childhood. Pedunculated and parahypothalamic types of hamartomas are attached to the floor by a narrow or wide peduncle in the absence of distortion of the overlying hypothalamus.
