Clinical reliability of posterior fossa scintigraphy.
Radioisotope imaging of the brain is considerably less useful in posterior fossa lesions than in supratentorial diagnosis, due to the peculiar technical difficulties and biological characteristics of infratentorial lesions. Exceptions are acoustic neurofibromas and probably meningiomas, which can be reliably detected. The importance is stressed of making skull and chest radiographs at the time of the examination, in order to enhance the diagnostic accuracy of the scintigraphic result.
