Asymptomatic intrapelvic meningocele is rare. Here, we report the case of a 30-year-old Chinese man who underwent sigmoidectomy due to megacolon. During the operation, an intrapelvic cyst was found and resected. Meningocele was confirmed by histological examination. The patient recovered well postoperatively with the exception of liquorrhoea. Conservative therapy was initiated, including draining, anti-infection and specific posture maintenance. During the following week, liquorrhoea was generally relieved and the patient was discharged. This is the first known report of liquorrhoea associated with intrapelvic meningocele resection successfully treated by conservative therapy. Our case indicates that conservative treatment may be considered for similar cases so that a second surgery is avoided.
