title: Perirectal abscess, colic, and dyschezia in a horse.
abstract: A quarter horse gelding with intermittent colic was diagnosed with a perirectal abscess and dyschezia. Rectal ultrasonography identified a multiloculated, fluid-filled mass. A perirectal abscess was diagnosed when the mass ruptured and drained into the rectum. The abscess was treated successfully with warm soapy water enemas and trimethoprim and sulfamethoxazole.
