両側肩関節血腫を来した一例

Abstract

Spontaneous hemorrhage in shoulder joint is rare. We experienced a patient with spontaneous hemorrhage in the bilateral shoulder joint. The case was a 61-year old woman who suffered from bilateral shoulder pain, especially in motion. She also complained of spontaneous bilateral shoulder pain, when the hemorrhage from her shoulder joint did not occur. We performed arthroscopic synovectomy, which revealed a small cuff-tear in the right side scope. No cuff-tear was found in the left side. No osteoblastic or osteolytic changes were also found at both sides. Synovium was extremely multiplied at both bursal sides. Specimens showed atypical synovitis. Diagnosis was spontaneous hemorrhage to the exclusion of PVS, hemangioma, aneurysm, and varix. Several authors have described that spontaneous hemorrhage occur in the shoulder joint associate with massive cuff-tears. In this case, we only found a small cuff-tear in the right side and not in the left. Her pain alleviated during a period from surgery to the final follow-up.
