Postrectal neoplasms and cysts

Abstract

The postrectal space is extensive and is in relationship to the sacral promontory and sacrum above and the coccyx below. Any of the structures in or adjacent to the space may be involved by or give rise to a postrectal neoplasm. In addition, a group of congenital neoplasms and cysts may also present in this space. Uhlig and Johnson in 1975 reviewed patients presenting to hospitals in the Portland, Oregon, U.S.A. area over a 25-year period. The population of Oregon in 1970 was 379,000. A total of 63 cases were reported. These tumours and cysts are an uncommon problem.
