case_images: SAG 3D T1+C MRI of the brain showing postoperative changes with right parietal porencephalic cyst and peripheral zones of contrast enhancement, suggestive of residual tumor (arrow).

case_images: Six years after the surgery, the patient was again referred to our institution by the monitoring outpatient neurologist due to noted neuroradiological thickening of the cyst wall and intermittent headaches (Figure 1).
case_images: Histopathology of the tumor. A: cellular pleomorphism, H&E stain, original magnification x400; B: bizarre and monstrous cells (arrows), H&E stain, original magnification x400; C: xanthomatous cells (arrows), H&E stain, original magnification x400; D: the sharp border between the tumor and the surrounding non-infiltrated brain parenchyma (asterisk), H&E stain, original magnification x4.. H&E: hematoxylin and eosin

case_images: Histopathology revealed brain parenchyma involved by a tumor proliferation represented by spindle and polymorphic atypical cells, small lymphocyte-like, large epithelioid-like, some with foamy cytoplasm, others with eosinophilic granular cytoplasmic inclusions and scattered large multinucleated cells with bizarre nuclei (Figure 2).
