Xanthogranuloma of the dura in systemic Weber-Christian disease.

A 51-year-old woman who had systemic Weber-Christian disease (WCD) displayed multiple xanthomatous lesions and a large xanthogranuloma of the tentorium cerebelli with signs of brainstem and cerebellar compression. Three other cases of dural xanthomatous lesions associated with systemic WCD have been reported. These dural and leptomeningeal xanthomatous lesions in WCD, a nonsuppurative inflammatory condition, are similar to those of Hand-Schüller-Christian disease, a quasi-neoplastic process.
