副神经节细胞瘤是发生在腹膜后间隙的肿瘤,属原发性腹膜后肿瘤,十分少见,常被误诊为“高血压病”及“消化道其他脏器的肿瘤”.我院遇到二例,开始的诊断均发生误诊.而此病主要的治疗方法是手术切除,所以如何早期发现,及早治疗,对疾病预后十分重要.现将二例总结如下.例1,男性,38岁.因阵发性头晕、头痛、心悸、多汗、乏力二十余年,伴右上腹、左颈部肿物 Paraganglioma is a tumor that occurs in the retroperitoneal space. It is a primary retroperitoneal tumor and is very rare. It is often misdiagnosed as “hypertension” and “tumors of other organs in the digestive tract.” The hospital encountered two cases. The initial diagnosis was misdiagnosed. The main treatment for the disease was surgical resection. Therefore, how to detect early and treat early is very important for the prognosis of the disease. Two cases are summarized as follows. Example 1, male, 38 years old. With paroxysmal dizziness, headache, palpitations, excessive sweating, fatigue for more than 20 years, with right upper quadrant and left neck masses.
