Adventitious bursitis in the plantar fat pad of forefoot presenting as a tumoral mass

Successful Treatment of Adventitious Bursitis With Marginal Resection in a 23-Year-Old Patient: A Case Report

Adventitious bursitis is an inflammatory condition affecting bursae. Distinct from primary or infectious bursitis, adventitious bursitis typically develops secondary to conditions such as rheumatoid arthritis, gout, or repetitive joint overuse. The resulting inflammation can lead to pain, swelling, and restricted mobility, significantly impacting patients' quality of life. In this paper, we present the case of a 23-year-old patient who reported to our clinic with swelling and pain localized to the right arm. Clinical examination, imaging studies, and histopathological analysis confirmed a preliminary diagnosis of adventitious bursitis associated with osteochondroma, which had exhibited rapid growth. Diagnostic evaluation included ultrasonography and MRI, which identified bursal inflammation and its relation to the underlying osteochondroma. The patient was treated successfully through marginal resection. Postoperative follow-up demonstrated significant symptom relief and restored joint functionality. This case underscores the importance of thorough diagnostic assessment and surgical management in achieving optimal outcomes for patients with adventitious bursitis.

Adventitial bursitis of the dorsal foot presenting as soft tissue masses in patients with autism spectrum disorder

Autism spectrum disorder (ASD) is an increasingly common neurodevelopmental disorder associated with impairments in postural control and repetitive patterns of behavior. Here, we describe two cases of adventitial bursitis of the dorsolateral feet in patients with ASD presenting as mass-like lesions. Both patients habitually sat in the W-position and were treated with ultrasound-guided aspirations with immediate relief of symptoms.

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

Adventitial (adventitious) bursae occur as a pathological condition in areas between soft tissues and bone where abnormal friction arises due to professional, traumatic, or sport activity. An atypical localization of an adventitial bursa was noticed on the ulnar margin of the distal forearm in a woman with a mild bone misalignment, as a professional disorder. The clinical presentation was one of subcutaneous mass with mild pain and no local signs of inflammation. A 1-year follow-up visit noted the degeneration of the bursa into a cystic lesion, as proved with a grayscale sonogram, using a 14 MHz linear transducer. This was an unexpected chronic evolution. A quick literature search found either resolution or a chronic course with complications as fibrosis, infection, and ulceration of adventitial bursitis.
