Question:
Reportability--Brain and CNS: Is meningioangiomatosis reportable as meningiomatosis (9530/1) or angiomatous meningioma (9534/0)? See Discussion.
Discussion:
Pathology report: Brain tumor, left side: Gliotic cortex and subcortical white matter with meningioangiomatosis (see Comment). Comment This specimen represents a meningioangiomatous lesion located in the leptomeninges that projects along the Virchow-Robin spaces into the underlying cortex. The surrounding brain parenchyma demonstrates reactive changes with astrogliosis and microgliosis. An intraparenchymal neoplasm is not seen. Meningioangiomatosis is a rare benign meningovascular hamartomatous condition and usually appears in young patients.
Answer:
Meningioangiomatosis is not reportable. It is a cortical lesion which may occur sporadically or in NF2 (neurofibromatosis type 2). It is not listed in ICD-O-3.
