No acute intracranial findings were demonstrated on this CT. A sclerotic lesion along the outer table of the skull (left occipital bone) was noted measuring 1.4 x 0.5 cm which most likely represents an osteoma.
Case Discussion
Osteomas are primary benign, usually asymptomatic bone lesions, often discovered incidentally.
Multiple osteomas are associated with Gardner syndrome.
