Suprasellar spindle cell lipoma

Spindle cell lipoma of the suprasellar region has not been reported in the literature. We report a case of a 4-year-old male with a suprasellar spindle cell lipoma. The patient presented with headaches and visual disturbances. An imaging study revealed a 4 to 5-mm suprasellar mass that was initially thought to be a lipoma or dermoid cyst. Pathologic examination from the partial resection showed a circumscribed lesion consisting of mature adipose tissue with intermixed uniform spindle cells associated with a mucoid matrix, morphologically consistent with a spindle cell lipoma. The spindle cells and vasculature demonstrated focal positivity with CD34 antibody. There was no evidence of lipoblasts, mitoses, necrosis, or osseous tissue.
