本文分析 24例经病理证实的嗜铬细胞瘤CT表现,并与B超手术结果进行了对照,旨在探讨 CT对该病定位、定性诊断价值和对临床治疗的指导作用。24例中,男11例,女13例。起源于肾上腺的肿瘤19例,异位嗜铬细胞瘤5例。CT扫描发现嗜铬细胞瘤具有一些特点:肿块一般较大、密度多不均匀、可伴有液化、坏死、钙化或囊变,增强时肿瘤实质明显强化,而坏死区无或略有强化。结果表明,CT对该病的定位率（95.8％）、定性率（87.5％）均高于B超（定位率83.3％,定性率62.5％）,提示CT是目前嗜铬细胞瘤影像诊断的主要方法。根据肿瘤的CT特点并结合典型的临床表现和生化异常,可进一步提高对嗜铬细胞瘤的诊断率。
This article analyzes the CT manifestations of 24 cases of pathologically confirmed pheochromocytoma and compares it with the results of B-surgery. The aim is to investigate the role of CT in the localization, qualitative diagnosis, and clinical treatment of this disease. In 24 cases, there were 11 males and 13 females. There were 19 cases of tumor originated from the adrenal gland and 5 cases of ectopic pheochromocytoma. CT scans showed that pheochromocytoma has some characteristics: the mass is generally larger, the density is more uneven, may be accompanied by liquefaction, necrosis, calcification, or cystic changes, and the enhancement of tumor parenchyma is markedly enhanced, while the necrosis area has no or slight enhancement. The results showed that the CT localization rate (95.8%) and the qualitative rate (87.5%) were higher than B ultrasound (positioning rate 83.3%, qualitative rate 62.5%), suggesting that CT is currently the main diagnostic imaging for pheochromocytoma method. According to the CT features of the tumor combined with typical clinical manifestations and biochemical abnormalities, the diagnostic rate for pheochromocytoma can be further improved.
