- Complete opacification of both mastoid air cells with rarefaction and bone defect seen at the lateral wall of the left mastoid bone associated with subcutaneous ring enhancing fluid collection seen adjacent to the left mastoid bone defect.
- Evidence of small epidural, limited by squamous suture, lentiform in shape, hypodense fluid collection with peripheral enhancement in the left temporal lobe at the same level of the left temporal subcutaneous abscess. However the separated bone appears to be intact apart from subtle thinning.
- No abnormal post contrast meningeal or dural enhancement.
