Headache, possible sinusitis and mastoiditis seen on CT scan , also possible cavernous malformation. History: headache. BRAIN: There is a mass in the central pons with complete hemosiderin rim measuring up to 12 mm. There is no evidence of associated developmental venous anomaly. There is no evidence of acute intracranial hemorrhage or acute infarct. There is mild cerebral white matter T2 hyperintensity bilaterally. The ventricles and basal cisterns are normal in size and configuration. There is no midline shift or herniation. The major cerebral flow voids are intact. The skull and scalp soft tissues are grossly unremarkable. There is fluid within the bilateral mastoid air cells. FACE: There are bilateral lens implants. There are a small amount of secretions in the right ethmoid sinuses. The rest of the paranasal sinuses appear unremarkable. There may be small periapical cysts in the mandible bilaterally. The parotid and submandibular glands are unremarkable. There is a prominent posterior disc-osteophyte complex at C5-6, which indents the spinal cord.
1. Small amount of secretions in the right ethmoid sinuses. 2. Findings compatible with a cavernous malformation in the pons.3. Fluid in the bilateral mastoid air cells may represent mastoiditis.4. Mild cerebral white matter T2 hyperintensity bilaterally may represent chronic small vessel ischemic disease. 5. A prominent posterior disc-osteophyte complex at C5-6 indents the spinal cord.
