Mimickers of soft tissue tumours in the hand and wrist are more frequent than true neoplastic lesions. Pseudotumours belong to a large and heterogeneous group of disorders, varying from normal anatomical variants, cystic lesions, post-traumatic lesions, skin lesions, inflammatory and infectious lesions, non-neoplastic vascular lesions, metabolic disorders (crystal deposition disease and amyloidosis) and miscellaneous disorders. Although the imaging approach to pseudotumoural lesions is often very similar to the approach to "true" soft tissue tumoral counterparts, further management of these lesions is different. Biopsy should be performed only in doubtful cases, when the diagnosis is unclear. Therefore, the radiologist plays a pivotal role in the diagnosis of these lesions. Awareness of the normal anatomy and existence and common imaging presentation of these diseases, in combination with relevant clinical findings (clinical history, age, location and skin changes), enables the radiologist to make the correct diagnosis in most cases, thereby limiting the need for invasive procedures.
手部和腕部软组织肿瘤的模仿者比真正的肿瘤性病变更为常见。假瘤属于一大类异质性疾病，包括正常解剖变异、囊性病变、创伤后病变、皮肤病变、炎症和感染性病变、非肿瘤性血管病变、代谢紊乱（晶体沉积病和淀粉样变性）以及其他杂类疾病。尽管对假瘤性病变的影像学检查方法通常与对“真正的”软组织肿瘤相似，但这些病变的进一步处理有所不同。仅在诊断不明确的可疑病例中才应进行活检。因此，放射科医生在这些病变的诊断中起着关键作用。了解正常解剖结构以及这些疾病的存在和常见影像学表现，并结合相关临床发现（临床病史、年龄、部位和皮肤变化），使放射科医生能够在大多数情况下做出正确诊断，从而减少侵入性检查的必要性。
