A Pelvic Digit as an Incidental Finding on Plain Radiography – A Case Report from Bulgaria

Abstract

Introduction: “Pelvic rib”, “pelvic digit (finger)”, or “eleventh digit (finger)” is a rare congenital anomaly, in which a finger-like bony structure is present in the soft tissue in the pelvic or abdomen (less common) area. Case Presentation: This case report presents a symptomatic “pelvic digit” discovered in a patient referred to the radiology department after prolonged unilateral hip pain, especially during long walks. To our knowledge, this is the first case report of unilateral pelvic digit occurrence in our region. It is an extremely rare condition that is often discovered incidentally due to the lack of clinical symptoms. Conclusion: To the best of the authors’ knowledge, this is the tenth reported case of symptomatic pelvic digit in the literature and four of them have required surgical intervention.
