Trichinellosis develops after ingestion of cysts in pork meat. It is one of the most important parasitic human pathogens in the world. It is, however, underreported in part because none of the clinical manifestations are pathognomonic. The primary mode of transmission is ingestion of raw meat. Among the symptoms are muscle pain, swelling, and myopathy. High-grade fever and other systemic symptoms are not unusual. The hallmarks are ophthalmic and musculoskeletal manifestations, particularly conjunctival haemorrhage with periorbital edema and subungual splinter haemorrhage. Although the majority of infections are mild and asymptomatic, severe infections can result in enteritis, periorbital edema, and myositis. . A 14-year-old male patient from Oromia Region, Arsi Zone, West Arsi Zone, Bishan Guracha area, which is almost completely encircled by mountains, presented with a complaint of worsening easy fatigability and asymmetric right thigh enlargement lasting one month. The pertinent physical examinations on presentation were puffy face and eyes, and there was a 4 cm by 5 cm mass on the right lateral thigh with no overlying skin colour change, on-tender, and no discharge. Eosinophilia of 14% was noticed on the complete blood count. The definitive diagnosis of trichinellosis was made by muscle biopsy. He was then managed with albendazole and prednisolone and improved.
Patients with periorbital edema, myositis, or eosinophilia should be evaluated for trichinellosis. Individuals who have these symptoms and a history of eating pork meat should be suspected of having trichinellosis. Before eating raw pork meat, it is recommended that it be cooked properly.
旋毛虫病是在摄入猪肉中的包囊后发病。它是世界上最重要的人类寄生虫病原体之一。然而,部分病例报告不足,因为其临床表现均无特异性。主要传播途径是摄入生肉。症状包括肌肉疼痛、肿胀和肌病。高热及其他全身症状并不少见。其特征为眼部和肌肉骨骼表现,尤其是结膜出血伴眶周水肿和甲下裂片状出血。虽然大多数感染症状轻微或无症状,但严重感染可导致肠炎、眶周水肿和肌炎。一名来自奥罗米亚州阿尔西地区西部阿尔西区比山古拉查地区(该地区几乎完全被山脉环绕)的14岁男性患者,主诉易疲劳加重且右大腿不对称肿大持续1个月。就诊时相关体格检查发现面部和眼部肿胀,右侧大腿外侧有一个4厘米×5厘米的肿块,皮肤颜色无改变,无压痛,无渗液。血常规检查发现嗜酸性粒细胞增多14%。通过肌肉活检确诊为旋毛虫病。随后给予阿苯达唑和泼尼松龙治疗,病情好转。
对于有眶周水肿、肌炎或嗜酸性粒细胞增多的患者,应评估是否患有旋毛虫病。有这些症状且有食用猪肉史的个体应怀疑患有旋毛虫病。建议在食用生猪肉前将其充分煮熟。
