Sonographic Diagnostic of an Adventitial Bursitis on the Distal Forearm: A Case Report

Abstract

A bursa is a thin sac filled with viscous fluid to facilitate friction and gliding. In the human body, there are two types of bursae: synovial bursae in well-defined positions and adventitial bursae, which develop in sites where friction or pressure increases. This case study is on a young woman with an old distal radial extremity fracture, with occupational exposure to pressure on distal ulnar forearm. She noticed a small and painful mass, with some mobility on the above-mentioned site. Sonography was used to detect a small fluid accumulation with features of adventitial bursitis. This case presents a rare localization of an adventitial bursitis. It is believed to have developed over the distal ulnar epiphysis, with a small bone malalignment, after an old and consolidated fracture, of the distal radial extremity.

Cystic Degeneration of an Atypical Adventitial Bursitis: Case Report and Literature Review

“…As she worked as a computer technician, with prolonged pressure of the ulnar margin of the forearm against the working table, the condition was considered as occupationally induced. 1 During the last year, she continued to work in the same manner, assuming the support position on the hard table for about 10 to 12 hours daily. The size of the tumor fluctuated a little over the time and the pain intensity oscillated between 1 and 5 on the visual analogue scale (VAS).…”

“…In this journal, a case was presented of a woman, 46 years old, with a small subcutaneous lump on the ulnar margin of the distal forearm. 1 Her history recorded a distal radial epiphysis fracture 11 years prior, which had resulted in a radial deviation of the distal forearm and a small, painful lump on the ulnar side of the wrist 1 year prior. The sonogram revealed an adventitial bursitis.…”
