assess sinuses, aspergillus: sinusitis. There are postoperative findings related to prior sinonasal debridement. However, there is diffuse pansinus mucosal enhancement and debris that displays low T2 and intermediate T1 signal. The enhancement along the walls of the sphenoid sinuses extend to the planum sphenoidale and anterior sella, where there are corresponding bony dehiscences that are more clearly depicted on CT. There are also dehiscences in the bilateral lamina papyracea and nasolacrimal ducts, with persistent enlargement of the left lacrimal sac, but no gross intraorbital extension, although the images are not optimized for the evaluation of the orbits. However, the left optic nerve canal is narrowed secondary to reactive thickening of the adjacent bone, which is also more clearly depicted on the prior CT. There is no evidence of intracranial abscess. There is no midline shift or herniation.
1. Postoperative findings related to prior sinonasal debridement with persistent extensive diffuse pansinus fungal disease.2. Inflammation along the walls of the sphenoid sinuses extend through bony dehiscences at the planum sphenoidale and anterior sella, which are more clearly depicted on CT. 3. Dehiscences in the bilateral lamina papyracea and nasolacrimal ducts, with persistent enlargement of the left lacrimal sac, but no gross intraorbital extension, although the images are not optimized for the evaluation of the orbits.4. The left optic nerve canal is significantly narrowed relative to the right secondary to reactive thickening of the adjacent bone, which is also more clearly depicted on the prior CT.
