Epidermoid Cyst of the Conus Medullaris and Cauda Equina: A case report / 대한척추외과학회지

The objective of this study is to report on a case of a huge epidermoid cyst in the conus medullaris and cauda equina in a 43 year-old lady with the characteristic MRI and histologic findings. She suffered from low back pain, hypoesthesia around the anus and urinary incontinence for over 20 years. Since 15 years previously, she gradually developed right foot drop and muscle atrophy. She underwent surgery and unfortunately, she developed complete paralysis below T12 after complete tumor excision. At postoperative 4 weeks, evidence of partial neurological recovery down to the L3 roots was observed, but as yet there has been no further neurological recovery. Although total surgical excision is thought to be the only radical treatment, we recommend partial tumor excision to avoid damaging the spinal cord and cauda equina during the surgical procedure, than the radical excision, because this cyst is a very slowly growing benign tumor.

Angiographic procedures and their applications maybe divided into following roups: I) procedures used to increased blood folw, as the angioplasty, II) procedures used to decreased blood flow, as the embolization and local infusion of vasoconstrictors and III) miscellaneous procedures. Transcatheter vessel occlusion was first performed in 1930 by Brook to occlude the carotid cavernous fistula by embolization of the surgically exposed carotid artery with muscle marked with a sliver clip injected directly into the internal carotid artery. Autologous clot, first used by Doppman(1968) to occlude a spinal arteriovenous malformation was quickly adopted use in traumatic hemorrhage with pelvic fracture, nonoperable aneurysm, gastrointerstinal hemorrhage and diagnosis and treatment of the tumors. In Kores, there have been several reports of transcatheter vessel occlusion after Han(1978) made a first report in the radiology part. In orthopedics part of Korea, Kim(1981) and Yoo(1982) reported the cases of surgical treatments of arteriovenous malformation without embolization. Also, in Korea, there has been no report of transcather embolizations of vascular diseases of the extremities, such as huge arterial aneurysm and dilated varicose vein. We reported the 4 cases who were treated at the Chonbuk National University Hospital between January 1987 and April 1988. Transcatheter vessel occlusion have such advantages : 1. The vascular status of the mass can be recognized prior to operation, such as biopsy. 2. Since the bleeding can be reduce, the operation can be performed easily. 3. Nonoperable huge arterial aneurysm could sometimes be treated only with transcatheter vessel occlusion adequately. 4. It can make a differential diagnosis with other vascular anomaly easy.
