He left AMA but then developed vomiting and returned. CT- Large peripherally enhancing mass lesion in the deep left cerebral hemisphere is associated with considerable vasogenic edema/infiltrative nonenhancing tumor. Mass effect results in left-to-right subfalcine herniation and entrapment of the right lateral ventricle. Findings are typical for glioblastoma. Intracranial abscess tumefactive multiple sclerosis and brain metastasis may mimic this appearance. Recommend supplemental imaging evaluation including gadolinium-enhanced MR brain. MRI- Dominant heterogeneously enhancing mass in the left basal ganglia/peri-insular region measuring 3.1 cm AP by 2.8 cm TR by 2.9 cm cc, with surrounding vasogenic edema resulting in mass effect and midline shift, as detailed above, concerning for high grade glial neoplasm versus metastasis. Additional leptomeningeal nodule in the right postcentral sulcus. Additional smaller peripherally enhancing lesion in the right lateral temporal region with suggestion of leptomeningeal component and measures approximately 0.8 x 0.8 cm, with mild surrounding vasogenic edema. They do a biopsy and pathology comes back as: – Brain tissue with extensive necrosis acute chronic inflammation, and rare microorganisms (on permanent section) -Brain, designated "left brain lesion", excision: – Brain tissue with extensive necrosis acute and chronic inflammation, reactive gliosis and occasional microorganisms Become a patron of TWiP Send your questions and comments to [email protected]
