Articular nodular fasciitis in the glenohumeral joint

Abstract

We describe a case of multiple intra-articular masses in the glenohumeral joint of a 15-year-old patient. The patient was treated with arthroscopic excision of the masses and synovectomy. Histological and immunohistochemical studies were consistent with those of a nodular fasciitis. Follow-up examination did not reveal recurrence at 6 months. In this article we report the first case of articular nodular fasciitis in the glenohumeral joint with unusual imaging findings.

Intra-articular nodular fasciitis of the knee: a rare cause of recurrent hemarthrosis

“…During the preoperative follow-up period, the patient underwent sequential MRI studies and no enlargement of the mass was demonstrated. These clinical findings are consistent with the characteristic features of intra-articular nodular fasciitis previously reported [2][3][4][5][6][7].…”

“…The prognosis of the condition is excellent and local recurrence of the lesion has never been seen among previously reported cases [2][3][4][5][6][7].…”

“…Intra-articular nodular fasciitis is very rare, and a search of the English-language literature revealed only 15 reported cases [2][3][4][5][6][7]. In the previous 15 cases, 10 tumors arose in the knee, 2 in the hand, 1 in the ankle, 1 in the shoulder, and 1 in the temporomandibular joint [2][3][4][5][6][7].…”

“…In the previous 15 cases, 10 tumors arose in the knee, 2 in the hand, 1 in the ankle, 1 in the shoulder, and 1 in the temporomandibular joint [2][3][4][5][6][7]. Patients with intra-articular nodular fasciitis typically complain of pain, swelling, restriction of joint motion, and a palpable mass around the joint [2][3][4][5][6][7]. Our patient had a nodular fasciitis within the knee and presented with a unique clinical manifestation of recurrent hemarthrosis.…”

Intra-Articular Nodular Fasciitis of the Knee: A Case Report of MRI Findings

“…Although information on imaging studies for intra-articular nodular fasciitis is limited, the current case showed nonspecific findings on MRI images, with homogeneous iso to low signal intensity on T1-weighted images and a heterogeneous, low to high signal intensity on T2-weighted images as reported previously (3)(4)(5)(6)(7). In this present case, conventional MRI with no contrast study showed nonspecific signal intensity of the lesion similar to previous reports, resulting in difficulty in making a precise pre-operative diagnosis on MRI.…”
