Prospective evaluation of quality of life in adolescent idiopathic scoliosis before and after surgery.

Study Design: Prospective observational study.

Objective: To assess patient quality of life before and after surgical treatment of adolescent idiopathic scoliosis (AIS) and determine whether an association exists between quality of life and curve magnitude, curve correction, and type of instrumentation.

Summary Of Background Data: Assessment of AIS surgery outcomes has always been based on analysis of radiographic measurements and postoperative curve correction.

Posterior fossa gangliocytoma with facial nerve invasion: case report.

A 5 year-old boy with a cerebellar gangliocytoma with a peripheral right facial paresis and ataxia is presented. His MRI showed a heterogenous, diffuse lesion, isointense on T1 and hyperintense on T2-weigthed sequences, involving the right cerebellar hemisphere with direct extension into the right facial nerve. The present case is the first description of a gangliocytoma with direct facial nerve invasion, as demonstrated for the facial nerve paresis and supported by MRI and surgical inspection.
