A Century With Craniopagus Twin Separation Surgeries: Nihilism to Optimism.

Craniopagus conjoined twins are extremely rare, reported 1 in 2.5 million live births. To date, 62 separation attempts in 69 well-documented cases of craniopagus twins have been made.

Primary spinal cord glioblastoma multiforme: a single-center experience.

Introduction: Primary spinal glioblastoma (GBM) are very rare tumors of the spinal cord, with dismal prognosis and their exact management is controversial. We attempt to formulate treatment guidelines for these extremely rare tumors based on our institutional experience and a comprehensive review of the literature.

Materials And Methods: In this retrospective study from 2008 to 2020, all the patients diagnosed with primary spinal GBM who underwent surgery at our institution were included.

Optic Nerve Hemangioblastoma: Review.

Background: Hemangioblastomas of the optic nerve are very rare tumors. They occur in association with Von Hippel-Lindau (VHL) syndrome; however, sporadic occurrences have been reported. We describe here a case of optic nerve hemangioblastoma in the absence of VHL and review the pertinent literature.

Usually these attacks were recognized at sites anatomically away from the primary lesion that were not explained by primary mass effect of the lesion.
