History of meningioma. Evaluate for residual/new disease. There are postoperative findings related to right-sided craniotomy, with encephalomalacia in the right frontal and temporal lobe surrounding the resection cavity. There are small unchanged foci of dural enhancement in the surgical bed region. There is no evidence of intracranial hemorrhage, mass, or acute infarct. The brain parenchyma and pituitary gland appear unremarkable. The ventricles and basal cisterns are unchanged in size and configuration. There is no midline shift or herniation. The major cerebral flow voids are intact. The orbits, skull, and scalp soft tissues are grossly unremarkable. There are secretions in the right maxillary sinus and what may represent a left antronasal polyp.
1. Postoperative findings related to right-sided craniotomy, with encephalomalacia in the right frontal and temporal lobe surrounding the resection cavity and small unchanged foci of dural enhancement in the surgical bed region, which may represent treatment effects, but otherwise no evidence of enlarging tumors to suggest recurrent meningioma. 2. Findings suggestive of acute right maxillary sinusitis and what may represent a left antronasal polyp.
