Neuroglial brainstem cyst

Case contributed by Dr Roberto Schubert

Presentation

Left hemiparesis and facial hypaesthesia.

Patient Data

Age: 30
Gender: Female
Modality: MRI

Large rounded cyst in the right pontine region crossing the midline and slightly indenting the IVth ventricle. Predominantly hyperintense T2 signal within the lesion with low signal sediment. On T1, the sediment is hyperintense and the rest of the contents isointense to brain tissue. No perifocal oedema. No contrast enhancement.

Case Discussion

Stereotactic biopsy and drainage of the lesion was perfomed. Histologic and immunohistochemistry findings were in keeping with a neuroglial cyst with marked internal astrogliosis and protein-rich content.
