Stereotactic decompression of a prepontine arachnoid cyst with resolution of precocious puberty.
A case of a prepontine (clival) arachnoid cyst is reported. The patient presented with isosexual precocious puberty. Treatment was initially with fenestration by suboccipital craniectomy, however, definitive treatment was via stereotactic transfrontal placement of a cystoperitoneal shunt. Normalization of endocrine function has occurred and has persisted for 1 year. This case is presented as a contrast to the two approaches for the treatment of arachnoid cysts. The case will be described and the literature reviewed.
