Key result
Total excision of a large skull tumor, initially reported as meningiosarcoma on imaging, revealed an eosinophilic granuloma on histology.
Case Report (n=1)
Eosinophilic granuloma of the skull can radiologically mimic meningiosarcoma, highlighting the importance of histological confirmation.
Eosinophilic granuloma of the skull may mimic meningiosarcoma on CT/MRI/angiography; case report leaves open the need for routine histological confirmation in atypical lesions.
Eosinophilic granuloma, a form of reticuloendothelial proliferation of unknown origin, can involve virtually any site and organ of the body. Involvement of the central nervous systems is very rare, but the skull is a common location. We present a case of a large eosinophilic granuloma of the skull, which on CT? MRI and angiography, was reported as meningiosarcoma. The tumour was totally excised, and histology disclosed an eosinophilic granuloma. Emphasis is given on radiology, and the literature is reviewed.

Pomonis et al. (1996) conducted a case report in Calvarial Eosinophilic Granuloma (n=1). Total excision was evaluated on Histological diagnosis. Total excision of a large skull tumor, initially reported as meningiosarcoma on imaging, revealed an eosinophilic granuloma on histology.
