title: Peritumoral cystic meningioma.
abstract: A case of 39 years old male is described who presented with headache, right-sided focal fits and decreased power in the right hand. CT scan brain showed a left fronto-parietal cystic lesion with centrolateral intramural nodule with homogenous enhancement. At surgery, the extra-axial lesion with cyst containing xanthochromic fluid had a well-defined capsule that could easily be separated from the peri-lesional cortical surface. The dural-based nodule with its cyst wall was resected in toto. The histopathology of mural nodule was reported as meningioma while the cyst wall histology revealed meningothelial cells.
