Primary giant myxoma of the temporal bone with major intracranial extension: presenting with hearing impairment and ear polyp

Myxomas are mesenchymal origin, benign tumor, constituting approximately half of the benign cardiac tumors. Occasionally, it may also occurs at other locations, though the intracranial location of a myxoma is considered exceptionally rare. Only isolated few cases of intracranial myxoma are reported in the literature, almost all were locally confined within the originating bone. The extensive Pubmed and Medline search yielded only eight cases of primary myxoma arising in the temporal bone with extension into intracranial compartment. However intracranial extension is limited as early detection, however, Osterdock et al reported a case also arising from temporal bone with extensive intracranial extension. Author report an interesting case of intracranial myxoma in 27yearoldmale, involving the temporal bone associated with extensive bony erosion and also extending into infratemporal fossa, mastoid, and frontoparietal region and a polypoidal mass protruding into external ear. To the best of knowledge of authors, temporal myxoma presenting with external ear polypoidal mass, which underwent successful surgical excision is not reported and represent first case in the world literature.
