To determine whether change in size is a characteristic of cavernous hemangioma of the liver.
Twenty-one focal masses in 21 patients were diagnosed as cavernous hemangiomas with imaging-guided percutaneous fine-needle biopsy performed between 2 weeks and 2 months after initial imaging study (computed tomography [CT] or ultrasonography [US]). Follow-up imaging examinations (CT, US, or magnetic resonance imaging plus US) were obtained at 5-84 months in all patients.
The cavernous hemangiomas ranged in size from 1.5 to 13.5 cm. At follow-up imaging, 19 (90%) of 21 lesions had not changed in size; the two remaining lesions increased by 1 and 2 cm over 3 and 10 months, respectively.
The size of the majority of cavernous hemangiomas remains stable for periods of follow-up ranging from 5 to 84 months. Growth of these lesions is not characteristic and, when it occurs, should prompt reassessment of the diagnosis.
确定大小变化是否为肝海绵状血管瘤的一个特征。
21例患者中的21个局灶性肿块经影像学引导下经皮细针穿刺活检诊断为海绵状血管瘤，穿刺活检在初次影像学检查（计算机断层扫描[CT]或超声[US]）后2周2个月进行。所有患者在584个月时进行了随访影像学检查（CT、US或磁共振成像加US）。
海绵状血管瘤大小在1.5至13.5厘米之间。在随访影像学检查中，21个病灶中有19个（90%）大小未变；其余两个病灶在3个月和10个月内分别增大了1厘米和2厘米。
大多数海绵状血管瘤在5至84个月的随访期内大小保持稳定。这些病灶的生长并非其特征性表现，一旦出现生长，应促使重新评估诊断。
