History of recurrent Rhabdomyosarcoma. On therapy. Comparison. Status post resection. Examination redemonstrates extensive postoperative changes of tumor removal via bifrontal craniotomy. CSF filled cavity within the right frontal lobe is believed to be the site of previous tumor invagination into the brain parenchyma. This is associated with surrounding vasogenic edema. Enhancement around the posterior edge of surgical cavity is believed to represent leptomeningeal scarring. No distinct tumor is identified however follow-up with an infused MRI is recommended. Expected postoperative changes of epidural thickening with minimal enhancement in bifrontal region is noted.In comparison to the prior non-infused CT of brain dated 6 -- 2 -- 2009 there is a slight increase in the soft tissue/fluid density within the paranasal sinuses.
Findings are believed to represent post operative change and not residual tumor. Follow-up with an infused MRI however is recommended for better assessment.
