RationaleRice bodies are usually found in several nonspecific chronic inflammatory diseases that are symptomatically dominated by primary disease and local compression symptoms. Rice bodies are usually detected by magnetic resonance imaging; however, some remote areas and areas with poor economic conditions do not have access to magnetic resonance imaging examination, which leads to delayed diagnosis of the disease.Patient ConcernsWe report the case of a 62-year-old man with pain in the metacarpophalangeal joint of his right middle finger and limited flexion activity of his middle finger.DiagnosesThe mass was 1 cm, well-circumscribed, soft, and painless. Ultrasound showed stenosing tenosynovitis with rice body formation.InterventionsThe patient underwent tenosynovectomy with synovectomy of the right middle finger tendon sheath under plexus block anesthesia.OutcomesNo postoperative complications were noted. A 6-month follow-up showed no recurrence. The activity of the patient's middle finger improved significantly.LessonsStenosing tenosynovitis with rice body formation is a very rare condition, and we use ultrasound for diagnosis. Ultrasound is convenient, rapid, inexpensive, and can obtain blood flow information, facilitate disease follow-up, and even allow ultrasound localization in advance for guided needle biopsy.Copyright © 2022 the Author(s).
