Osteolipoma of the Tuber Cinerium – a case report

Gender, Age

Female, 16

Diagnosis

Osteolipoma of the Tuber Cinerium

History

A 16 year old female presented with history of occasional episodes of syncope, since 2006.

Findings

Sagittal reformatted CT image demonstrates a predominantly calcified lesion (white arrow) with focus of fat density (red arrow) abutting the Tuber Cinereum, suggestive of an osteolipoma

Discussion

Osteolipomas arise from remnants of the meninx primitiva or from the mesenchyme of the craniopharyngeal duct. The typical site of origin is from the tuber cinereum of the hypothalamus between the pituitary stalk and the mammilary bodies. The lesions consist of central adipose and peripheral osseous tissue which distinguishes them from intracranial lipomas at other locations. They project into the suprasellar or interpeduncular cisterns. The lesions are mostly incidental findings on CT or MRI scans done for other reasons.

Pearls

These lesions are usually not associated with significant clinical symptoms or abnormalities and do not need surgical excision.
