Intraspinal Neurenteric Cyst Associated with Increased Intracranial Pressure

Abstract

A case of neurenteric cyst in the lumbosacral region is reported. A 54-year-old woman was admitted with symptoms of increased intracranial pressure. Neuroradiological examinations revealed no abnormal findings in the intracranial region except for communicating hydrocephalus. Myelography showed complete block in the lumbar region. A tumor of the a lumbosacral region was diagnosed and considered to be responsible for the increased intracranial pressure. Subtotal removal of the tumor was performed. After the surgical treatment, the symptoms of increased intracranial pressure disappeared. Microscopic examination of the cyst wall disclosed loose fibrous connective tissue lined with ciliated columnar cells. Histological diagnosis was a neurenteric cyst. The clinical and embryogenic features are discussed.
