The ingestion or accidental insertion of foreign bodies is extremely rare before 6 months of age. We report the case of a 3-month-old infant with a sewing needle into the right hepatic lobe, without symptoms. The extraction was performed through laparotomy. The issue is revisited, and the decision making tree is discussed.

Synovial sarcoma is an uncommon fibroblastic soft tissue neoplasm, commonly arising near, but not necessarily from, the synovium of joint capsules, bursae or tendon sheaths. The radiological diagnosis is difficult. We present a case of synovial sarcoma studied with plain film radiography, CT, and pathology that had an unusual extensive calcification, which complicated its radiological diagnosis.
