Pilomyxoid astrocytoma (PMA) is a recently defined pediatric brain tumor; PMAs were previously classified within the pilocytic astrocytoma (PA) category. Nevertheless, PMA has different histological features and has been shown to behave more aggressively than PA. These findings indicate that PMA may be a unique entity that is distinct from PA, or it may be an unusual variant. To increase awaren...

Bone metastasis from a spinal cord astrocytoma has been reported only twice in the English medical literature. It is generally known that bone metastasis is found after the initial diagnosis with/without intervening surgery rather than being found at the time of the diagnosis of astrocytoma. The purpose of this article is to report for the first time a case of concurrent bone metastasis from a ...

an apparently healthy sleep into deep coma; or how viciously a pernicious malaria infection may hide itself behind a very varied clinical picture resembling a score of different conditions of almost any organ or system of the body. Cerebral malaria has been diagnosed as cerebrospinal meningitis; and in this journal only recently attention has been drawn to the fact that even the function and st...

Syncope has been defined as a transient, brief, self-limited loss of consciousness due to global cerebral hypoperfusion (Brignole et al. 2004). The specific pathophysiology sets syncope apart from other conditions causing transient loss of consciousness (TLOC), such as epilepsy. The major causes and mimics of TLOC are summarised in figure 1. History-taking is the most important tool to distingu...

The authors report a case of intracranial aspergillosis secondary to immunosuppression. Signal intensity changes in the lesion on brain MR are compared with gross and histopathologic findings at autopsy. A peripheral ring of low signal intensity relates to a dense population of Aspergillus hyphal elements and small areas of hemorrhage. CT findings are included for comparison.
