 There is no evidence of intracranial mass or enhancing lesions. No evidence of a bleed, mass effect, or edema. There is normal ventricular size with normal gray-white matter differentiation and no midline shift.Punctate nonspecific high signal lesions on T2 and FLAIR is seen in the corona radiata, likely chronic ischemic small vessel disease. There are no restricted diffusion abnormalities. There are no susceptibility abnormalities.A lobulated mucosal retention cyst is seen in the left maxillary sinus. A small mucosal retention cyst is seen also in the right maxillary sinus. The left middle turbinate has been resected. Along the left antrostomy, there is an area of abnormal soft tissue with cerebriform pattern. The lesion has heterogeneous high signal in T2 and FLAIR and is enhancing. A nonspecific soft tissue nodule is seen along the musculature in the left suboccipital region. Flow voids of the anterior intracranial vascular structures are present.
1. No definite evidence of metastatic lesions in the brain.2. Abnormal soft tissue is seen at the left antrostomy, with imaging characteristics suggestive of possible inverted papilloma, although correlation with previous surgical history is recommended. Differential diagnosis would also include a metastatic lesion or other primary sinus neoplasm.3. A nonspecific heterogeneous small soft tissue nodule is seen along the posterior musculature in the left suboccipital region. Recommend correlation with physical examination and with any history of trauma. Different diagnosis would include hematoma or possible metastasis.Dr. Lauren Feld was notified by Dr. Arie Franco on 8/6/2015 at 4:00 p.m.
