Cerebellar pilomyxoid astrocytoma
Pilomyxoid astrocytomas (P.M.A) are new class of Pilocytic Astrocytoma (P.A.) which typically have their origin in hypothalamus and chiasmatic region. There are very few case reports of PMAs arising from cerebellum. Their imaging features are similar to PA but they behave more aggressively than PA. The authors report a case of 10 year old male child who presented with right cerebellar tumour di...
متن کاملPilomyxoid astrocytoma of the cerebellar vermis in an elderly patient
BACKGROUND Pilomyxoid astrocytoma (PMA) has recently been accepted as an aggressive variant of pilocytic astrocytoma with distinct histopathological features. PMAs have been frequently described in the pediatric population with a predilection for the hypothalamic/chiasmatic region. CASE DESCRIPTION A 72-year-old African American male presented with 6 months of memory loss, difficulty expressi...
متن کاملPilomyxoid astrocytoma in cerebellum.
Pilomyxoid astrocytoma is a new identified variant type of pilocytic astrocytoma, and typically locates in the hypothalamic and chiasmatic region. Herein, we reported a nine-year-old boy with pilomyxoid astrocytoma in the cerebellum. MRI scanning showed a tumor involved the cerebellar vermis, tonsil, the forth ventricle and brainstem. It was homogeneous isointensity on T1WI, relative hyper-inte...
متن کاملPilomyxoid Astrocytoma of the Brainstem
A pilomyxoid astrocytoma is a recently described tumor that occurs predominantly in the hypothalamic-chiasmatic region and is rarely found elsewhere. It has similar features as pilocytic astrocytomas, but has distinct histological characteristics and a poorer prognosis. A pilomyxoid astrocytoma is an aggressive tumor, and increased awareness is necessary with a suspect case. We present the firs...
متن کاملPilomyxoid astrocytoma: expanding the imaging spectrum.
BACKGROUND AND PURPOSE Pilomyxoid astrocytoma (PMA) is a recently described variant of pilocytic astrocytoma (PA) with unique clinical and histopathologic characteristics. Because the histopathology of PMA is distinct from that of PA, we hypothesized that PMAs would display distinctive imaging characteristics. We retrospectively reviewed the imaging findings in a large number of patients with P...
