An adult female, wild North American porcupine (Erethizon dorsatum) presented with bilateral cataracts and naso-ocular discharge. A pregnancy was identified by radiography with a near-full-term fetus, which was delivered stillborn 4 wk later with hard, developed quills. At that time, a repeated examination and further imaging, including computed tomography, demonstrated a uterine mass that was identified as a choriocarcinoma following ovariohysterectomy. Additionally, numerous exfoliated quills were discovered throughout the abdomen, most of which were removed during the surgical procedure. Ultimately, development of peritonitis despite medical care led to the porcupine's death. Necropsy confirmed a wide migration of the quills with extensive serosal adhesions and granulomas affecting liver, lungs, urinary bladder, kidneys, and gastrointestinal tract.
一只成年雌性野生北美豪猪（北美豪猪属）出现双侧白内障和鼻眼分泌物。通过X光检查发现其怀有身孕，胎儿已近足月，4周后产出死胎，体表有坚硬且已发育的刺。当时，经过反复检查和包括计算机断层扫描在内的进一步影像学检查，发现子宫有肿物，卵巢子宫切除术后确诊为绒毛膜癌。此外，在整个腹部发现了大量脱落的刺，大部分在手术过程中被取出。最终，尽管进行了医疗护理，豪猪还是因腹膜炎发展而死亡。尸检证实刺广泛迁移，伴有广泛的浆膜粘连和肉芽肿，影响肝脏、肺、膀胱、肾脏和胃肠道。
