To learn common locations and imaging findings of tumors cyst of the brain with a mural nodule (CBMN).
CBMN is one of the radiologic patterns of central nervous system tumors.
In a classification of the patterns of contrast enhancement in the brain and meninges,
this one is considered a subtype of intra-axial enhancement lesions included in the category of fluid-secreting low-grade primary neoplasm.
The most common are: hemangioblastoma,
pleomorphic xanthoastrocytoma and,
as less common,
Findings and procedure details
Radiology Features Pilocytic astrocytoma Most common in the cerebellar hemispheres.
Other typical location is optic nerve/chiasm/tract.
In T1-weighted sequences,
the solid portion of the CMNT is iso/hypointense to gray matter while thecyst content is iso- to slightly hyperintense to cerebrospinal fluid (CSF).
In T2 and fluid attenuated inversion recovery (FLAIR) sequences,
the solid portion is hyperintense to gray matter while thecyst content is hyperintense to CSF.
In FLAIR sequences,
CBMN is an important radiological pattern of brain lesions.
radiologic characteristics of the lesions can help to the differential diagnosis,
that can be related,
to primary or secondary brain tumors.
