Transrectal and transperineal sonography in the diagnosis of hydradenitis suppurativa.

Abstract

Background. The aim of this paper is to present the application of transrectal and transperineal sonographies in the differential diagnosis of the hydradenitis suppurativa with the anal fistula.

Patients and methods. Transrectal and transperineal sonographies were performed in 8 patients with a clinical diagnosis of the anal fistula (6 patients) and the hydradenitis suppurativa (2 patients) in order to define precisely the relation of the inflammatory changes to the anal canal.

Results. In all patients the endosonography showed the preserved structures of the anal canal and the transperineal approach proved the superficial location of lesions.

Conclusions. Transrectal and transperineal sonographies are helpful in the differentiation between the hydradenitis purulenta and the anal fistula. The use of both methods enables a correct diagnosis.
