On physical examination, a 5 x 10-cm abdominal mass was found in an eight-year-old female rhesus macaque. Radiography revealed an opaque mass in the cranial portion of the abdomen, displacing the stomach craniad. Percutaneous biopsy obtained hair with little tissue, confirming a diagnosis of trichobezoar. Initially, the hairball was medically managed by oral administration of lubricants. Medical management proved unsuccessful, the macaque began to lose weight, and two gastric trichobezoars were subsequently removed surgically. Normal appetite and activity were regained within one week. Gastric trichobezoars may lead to severe clinical illness, and should be considered in the differential diagnosis for anorexia and/or weight loss in any nonhuman primate. Trichobezoars may also be detected and treated prior to development of illness.
体格检查时，在一只8岁雌性恒河猴身上发现一个5×10厘米的腹部肿块。放射检查显示腹部颅侧有一个不透光的肿块，将胃向颅侧推移。经皮活检获取的毛发多而组织少，确诊为毛粪石。最初，通过口服润滑剂对毛球进行药物治疗。药物治疗未成功，猕猴开始体重减轻，随后通过手术切除了两个胃毛粪石。一周内恢复了正常食欲和活动。胃毛粪石可能导致严重的临床疾病，在任何非人灵长类动物出现厌食和/或体重减轻的鉴别诊断中都应考虑到。毛粪石也可在疾病发展之前被检测和治疗。
