Retrorectal abscess with neurologic involvement of the lower extremities: report of a case.

A case of retrorectal abscess with neurologic involvement of both lower extremities is presented. The authors believe that an adequate description of this entity is necessary for the clinician, insofar as rectal suppurations rarely cause neurologic symptoms. The clinician must be alert for the possibility of the presence of various presacral tumors, whose treatment and prognosis present much graver problems.
