Abstract
OBJECT: Cystic dilation of the ventriculus terminalis (CDVT) is a rare anatomical variation and may become symptomatic. Existing literature regarding CDVT is limited, and as a result, the clinical characteristics and management strategy of CDVT is unclear. We report in this study six cases of CDVT in our institution, and provide a review of current literature.
METHODS: We included six patients with CDVT in Beijing Tiantan Hospital between September 2010 and June 2015. All patients were surgically managed. Gender, age, clinical presentations, radiological features, operative methods, surgical outcomes were retrospectively reviewed. We evaluated the clinical outcomes and postoperative radiological changes of our surgical series of CDVT and compared them with similar reports.
RESULTS: All the six patients were female, with a median age of 50.0 (Interquartile Range: 25.8-54.0) years. Surgical management of cyst-subarachnoid shunting using T-catheter after myelotomy was successfully performed in all patients. During an average follow-up period of 41 months, relief of clinical symptom, especially low-back pain and sciatica, were observed in all six patients. No patients experienced recurrence of symptoms during follow-up, and postoperative MRI scan demonstrated no regrowth of the lesion. Patients with focal neurological deficits and sphincter disorders also achieved symptom relief from the procedure.
CONCLUSIONS: CDVT is an extremely rare cause of conus medullaris syndrome with unclear treatment strategy. Our successful surgical management of six cases via cystic-subarachnoid shunting using T-catheter for CDVT drainage provided a potential option for CDVT treatment.
