Angiofollicular lymph node hyperplasia is a relatively rare benign lesion. In 1954 Casteman described the first case of this process occurring in the anterior mediastinum. This lesion was subsequently described in a number of case reports under various names including Castleman's disease, lymph nodal hamartoma, follicular lympho-reticuloma, angiofollicular lymph-node hyperplasia, angiomatous lymphoid hamartoma, and benign giant lymphoma. Although the mediastinum is the most common location, they also occur in other areas of the body, usually where lymph nodes are normally found. However, intraspinal location has been seldom described in literatures. Recently, authors experienced a case of angiofollicular lymph node hyperplasia in the thoracic spinal canal, which was operated upon for paraparesis below T10, in a 17 year old male. The tumor was located between the levels of T8 to T10, and was encircling the subjacent spinal cord. This lesion was successfully removed. The patient is in good condition postoperatively. A brief review of pertinent literatures was made.
