Although it is a benign lesion, even then delay in diagnosis and treatment may lead to significant morbidity. The authors report a very rare case of giant posttraumatic intradiploic pseudomeningocele involving the occipital bone, occipital condyles, and clivus. The pathogenesis and management of intradiploic CSF collection are discussed.<\/jats:p>\n<jats:p>This 16-year-old boy presented with a history of enlarging swelling in the suboccipital region associated with headache, lower cranial nerve palsy, and features of high cervical compressive myelopathy. Investigations revealed a giant intradiploic lesion involving the occipital bone, condyles, and clivus associated with secondary basilar invagination, hydrocephalus, and syringomyelia. Intrathecal contrast administration did not reveal communication of intradiploic space with the subarachnoid space. A large occipital craniotomy was performed. A linear fracture and dural defect in the midline was identified, which was closed with fascial graft after removing the inner table of the skull. Cranioplasty was performed using the expanded calvarial bone. Ventriculoperitoneal shunt insertion was performed for hydrocephalus, and the patient improved remarkably.<\/jats:p>\n<jats:p>Posttraumatic intradiploic CSF collection, although a benign condition, may present with severe complications if treatment is delayed. Early diagnosis and treatment is essential. The authors suggest that this condition should be treated early, as for growing skull fractures.<\/jats:p>","DOI":"10.3171\/2011.10.peds1181","type":"journal-article","created":{"date-parts":[[2011,12,30]],"date-time":"2011-12-30T17:13:01Z","timestamp":1325265181000},"page":"82-85","source":"Crossref","is-referenced-by-count":23,"title":["Giant intradiploic pseudomeningocele of occipital bone"],"prefix":"10.3171","volume":"9","author":[{"given":"Rajinder","family":"Kumar","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Sarat P.","family":"Chandra","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Bhawani Shanker","family":"Sharma","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1754","reference":[{"key":"b1-0090082","series-title":"Indian Pediatr","doi-asserted-by":"publisher","first-page":"271","DOI":"10.1007\/s13312-010-0036-z","article-title":"Post-traumatic intradiploic pseudomeningocele","volume":"47","author":"Agrawal","year":"2010"},{"key":"b2-0090082","series-title":"Surg Neurol","doi-asserted-by":"publisher","first-page":"80","DOI":"10.1016\/0090-3019(94)90212-7","article-title":"Growing skull fracture of the orbital roof","volume":"41","author":"Bayar","year":"1994"},{"key":"b3-0090082","series-title":"J Neurosurg","doi-asserted-by":"publisher","first-page":"687","DOI":"10.3171\/jns.1971.34.5.0687","article-title":"Leptomeningeal cyst of the posterior fossa.
