Although intraspinal osteochondromas are known to cause neurological deficits, intracranial osteochondromas with neurological compromise are very rare. Case Description: The authors report an exceptional case of a quadriparetic 73-year-old patient with a basioccipital bone osteochondroma growing into the foramen magnum. The embryology, differential diagnoses, and optimal management strategies are discussed. Conclusion: Although extremely rare, osteochondromas should be included in the differential diagnoses of tumors within the foramen magnum. For the tumors originating from the basioccipital bone, a simple medial suboccipital approach might suffice, while for ventral tumors, a far lateral transcondylar approach is necessary to avoid any neurovascular complications. Despite potentially catastrophic presenting symptoms, these tumors are pathologically benign and complete excision often results in long-term cure. To the best of our knowledge, this is the first report of an osteochondroma arising from the basiocciput.","thumbnailUrl":"https://sni-digital-videos.s3.amazonaws.com/articles/aafeebdc-79b6-40c9-84c9-e2a2d4004cef/featured/hero-1782420952400.png","publishDate":"2012-02-15T00:00:00.000Z","doi":"10.4103/2152-7806.92937","categories":["Original Article"],"fullTextUrl":"http://sni.wpengine.com/wp-content/uploads/2015/05/3299/SNI-3-21.pdf"}
