Female, 45 years old, history of right ethmoid cancer status post chemoradiation. Redemonstrated are findings compatible with sinonasal tumor resection and bilateral frontal craniotomy. Thick enhancing tissue along the ethmoid roof and subjacent to the frontal craniotomy is unchanged. Mild soft tissue thickening and enhancement along the right lamina papyracea, and extending along the walls of the right maxillary sinus, has also not significantly changed.No evidence of any destructive or masslike lesion is seen in the ethmoid operative bed. Since the prior examinations, peripheral mucosal thickening and enhancement has increased within the left sphenoid sinus, but this enhancement conforms to the sinus wall and shows no evidence of invasion. Nonenhancing secretions are also evident within the left sphenoid sinus.Mild postoperative encephalomalacia affects the inferior frontal lobes along the operated ethmoid roof similar to prior. A few additional scattered small foci of nonspecific T2 hyperintensity are seen in the brain parenchyma without significant interval change.No evidence of parenchymal edema or mass effect is seen. No new or pathologic intracranial enhancement is detected. No evidence of significant intracranial hemorrhage or abnormal extra-axial fluid is seen. The ventricular system is patent and normal in size.
1. Stable postoperative findings compatible with sinonasal tumor resection. Enhancing soft tissue along the reconstructed ethmoid roof and subjacent to the frontal craniotomy is likely postsurgical in nature and not significantly changed.2. Mild increase in sphenoid sinus mucosal thickening is most likely inflammatory in nature.3. No new brain lesions and no evidence of brain parenchymal metastases.
