Abstract
We report two cases of endodermal cyst. Case 1, a 9-year-old male, was admitted to our hospital because of rapidly progressing paraplesia. MRI of the spine revealed that a low intensity cystic mass in the T1 weighted image was located ventrally at the level of the first-second thoracic vertebral bodies. The cyst was removed except for some parts of the cyst wall. He recovered from paraplesia after surgery. The recurrence of the cyst was recognized one year after surgery. The cyst was removed again and did not recur. Case 2, a 70-year-old female, was admitted to our hospital with an intramedurally lesion of the spinal cord at the Th7/8 on MRI. The cyst was removed microscopically. Her pain of the lower extremities decreased, but muscle weakness of her right ankle appeared. Pathological examination revealed endodermal cyst in both cases.
