Supralevator anorectal abscess presenting as acute low back pain and sciatica.
Anorectal abscess is a suppurative process that begins in the anal glands. Clinical presentation is variable and depends on the direction and tissue plane along which the infection tracks. All cases require urgent incision and drainage. We report an unusual case of a supralevator abscess in a man who presented to the emergency department on two occasions with acute low back pain and sciatica. The case demonstrates the importance and difficulty of identifying the exceptional case among the numerous routine cases of mechanical low back pain. Attentiveness to atypical features should direct the clinician to a more extensive evaluation for serious illness. The case also illustrates that sciatica is not a diagnostic end-point but rather a label for a pain syndrome that encompasses a long differential diagnosis.
