Intradural Extramedullary Mature Cystic Teratoma

Abstract

The occurrence of cystic teratomas in the absence of previous surgery or lumbar puncture is uncommon. Even rarer are reports of these lesions in aged patients. Of particular interest in this case is the fact that this patient had not undergone any previous lumbar procedures nor did he have a history of spinal dysraphism. Though rare, this entity should be included in the differential of cystic intradural spinal cord lesions.

Spinal intradural extramedullary mature cystic teratoma in young adult: a rare tumor with review of literature

“…7 Besides congenital abnormality, cases have been reported where a history of trauma or surgical interventions (example lumbar puncture) often preceded the clinical presentation in adults. 6 However, present patient did not show any evidence of spinal dysraphism during physical and radiologic examination. Also, he had not previously undergone any spinal surgery or procedure.…”

Subtotal resection of an intradural mature teratoma in an adult presenting with difficulty initiating micturition

“…The traditional theory is that in the early weeks of embryogenesis, the primordial germ cells are misplaced into the dorsal midline, during migration to the gonadal ridges from the primitive yolk sac. [259] This is supported by the fact that there is an association between spinal teratomas and midline spinal dysraphic defects. [2610] An alternative explanation is provided by the dysembryogenic theory, which suggests that pluripotent cells from the caudal cell mass in the developing embryo can result in a teratoma with multiple erroneous gene function and cellular inductive interactions.…”

Totally cystic intradural schwannoma in thoracic region

“…Totally cystic tumor as seen in our case is hypointense on T1 and hyperintense on T2-weighted images and has to be differentiated from Tarlov cyst, arachnoid cyst, neurenteric cyst, epidermoid cyst, and cystic teratoma. [111213]…”
