ULTRASOUND EVALUATION OF UMBILICAL PILONIDAL SINUS

Abstract

Introduction: Pilonidal sinus is a chronic inammatory disorder caused by a hair fragment penetrating the skin & producing a foreign body reaction leading to the formation of sinus coated with granulation tissue. Pilonidal sinus occurs in many areas of the body such as sacro-coccygeal region, web of ngers, umbilicus, shaft of penis, breast, axilla , perineum, nose etc. Aims: To study the role of ultrasound in Umbilical pilonidal sinus. Materials & methods: Study includes 6 patients who were diagnosed to have Umbilical pilonidal sinus on ultrasound. Results: Ultrasound diagnosis of Pilonidal sinus in all 6 patients was conrmed during surgery & on histopathological studies of surgical specimen. Conclusions: Ultrasound is an important tool in diagnosing Umbilical Pilonidal Sinus.
