Synovial lipomatosis (also known as lipoma arborescens) is a rare and benign lesion affecting synovium-lined cavities. It is characterized by hyperplasia of mature fat tissue in the subsynovial layer. Although the most commonly affected site is the knee joint, rarely additional locations such as tendon sheath and other joints are involved. We present a case of synovial lipomatosis of the glenohumeral joint in a 44-year-old man. The clinical data radiological studies and histopathologic results are described, as well as a review of the current literature.

Synovial Lipomatosis

AbstractSynovial lipomatosis (SL; lipoma arborescens) is a tumor-like condition with villous proliferation of the synovium. The exact etiology of SL is still unknown. The knee is the most commonly involved part. The goal of this retrospective study was to report the results of arthroscopic synovectomy in patients with SL in their knee joints as well as to emphasize the importance of considering this pathology when treating patients with recurrent knee joint effusions. In total, 21 patients (8 females and 13 males) were evaluated retrospectively from May 2009 to July 2014. The mean follow-up period was 29.13 (range, 12–61) months. The mean duration of compliance was 22.76 (range, 7–61) months. All patients were evaluated by Knee Society score pre- and postoperatively. The mean preoperative and last follow-up Knee Society scores were 67.82 and 88.23 points, respectively. There was a significant difference between the preoperative and postoperative Knee Society scores (p = 0.0001). Histopathological examinations showed that the subsynovial layer exhibited diffuse replacement by mature fat cells that had formed villous projections. In addition, infiltration of mononuclear inflammatory cells was observed at different stages. SL is a nondestructive and benign tumor pathology of the knee joint without a clearly identified etiology. The main difficulty in diagnosis is lack of clinical practice.

Tenosynovial Giant Cell Tumour

Giant cell tumor of the tendon sheath is a common benign lesion of the hand. They are also known as tenosynovial giant cell tumours. Magnetic resonance imaging is the imaging modality of choice and the current treatment is surgical excision of the lesion. This lesion is particularly known for its high recurrence rates. Here, we present a case of a recurrent tenosynovial giant cell tumour of the flexor tendon sheath of the index finger at the distal palmar crease. Diagnosis was confirmed by MRI and the lesion was excised. Histopathology revealed a localized type of tenosynovial giant cell tumour.

Background: The use of ultrasound to perform quantitative musculoskeletal (MSK) measurements requires reliability among different providers with varied levels of experience and training. Recent studies have shown that physical therapists (PT) can reliably measure the glenohumeral joint space using ultrasound imaging (USI) and operator experience or well defined training protocols influences the reliability. Few studies have reported the reliability of medial knee gap measurements with USI. Objective: Evaluate inter- and intra-rater reliability of a novel approach to measuring knee gapping using experienced and trained novice clinicians. Design: Inter-rater and intra-rater reliability study Setting: Physical therapy program Participants: Novice researchers were three upper-year Doctor of Physical Therapy students. Experienced researchers were two PT certified in MSK USI with eight years of experience. Methods: A total of 166 images of two subject’s medial knee joint gaps were captured in resting by a single experience researcher. Three novice researchers, who underwent a three-hour training protocol and two experienced researchers measured the images individually. Measurements were taken using standardized bony landmarks and internal calipers. All researchers were blinded to the subjects and results. Main outcome measures: Data was analyzed using two-way ICC mixed-model single measurement, SEM run for all researchers compared with experienced researcher one. Results: An excellent degree of reliability was found for both intra-rater and inter-rater measurements for Novice One and a good degree of reliability was found between Experienced One and Novice Two and Three. Conclusion: Both experienced and novice researchers attained a clinically significant ICC when compared to Experienced One. An accurate and reliable measurement of the medial knee joint gap maybe useful for further studies and help with diagnosis of joint pathologies. Level of study: IIB

Lipoma arborescens is a rare synovial lesion characterized by villous proliferation of the synovial membrane and replacement of subsynovial tissue with mature fat cells. The knee joint is the most frequently affected site, particularly in the suprapatellar pouch. However, there have been few reports regarding shoulder involvement, including the glenohumeral joint and subacromial subdeltoid bursa, associated with rotator cuff tear. This article reviews the case of a 67-year-old man who presented with lipoma arborescens of the left shoulder, associated with a rotator cuff tear. Sonography revealed a fluid collection with thickening of the synovial membrane with hyperechoic villous proliferation, located in the subdeltoid bursa. An arthroscopic synovectomy and rotator cuff repair were performed. Arthroscopic findings included yellow frond-like synovial proliferation of the synovium. Postoperatively, the patient was asymptomatic, and the lesion did not recur. Although magnetic resonance imaging is the first-line imaging modality for diagnosis of this lesion, sonography may be used initially for evaluation of chronic joint swelling. In addition, it can be useful for detection of recurrence after synovectomy. This case illustrates the typical sonographic features of lipoma arborescens.
