We report a case of ruptured low-grade appendiceal mucinous neoplasm with an impressive toy puffer ball-like appearance on magnetic resonance imaging. A 79-year-old woman with lower abdominal pain underwent computed tomography scanning, revealing a 6-cm mass in the right lower abdomen. T2-weighted images showed a radial low-signal structure in the central area of the mass, which was presumed to be fibrotic. Pathology confirmed ruptured low-grade appendiceal mucinous neoplasm. The rupture point was at the tip of the appendix, coinciding with the center of radial fibrosis. The unique morphology of the puffer ball-like appearance in this case may be a characteristic of low-grade appendiceal mucinous neoplasms.
我们报告一例低度阑尾黏液性肿瘤破裂病例，该病例在磁共振成像上呈现出令人印象深刻的玩具河豚球状外观。一名79岁下腹部疼痛的女性接受了计算机断层扫描，结果显示右下腹有一个6厘米的肿块。T2加权图像显示肿块中心区域有一个放射状低信号结构，推测为纤维化。病理证实为低度阑尾黏液性肿瘤破裂。破裂点位于阑尾尖端，与放射状纤维化的中心重合。该病例中独特的河豚球状外观形态可能是低度阑尾黏液性肿瘤的一个特征。
