To evaluate differences in clinical and radiologic features of small and large pheochromocytomas.
This study included 39 patients with adrenal pheochromocytomas. Several clinical and radiologic features were statistically analyzed and compared between small and large pheochromocytomas.
No significant differences were found in clinical features between them. Small pheochromocytomas had more relatively homogeneous attenuation although large pheochromocytomas had more cystic or necrotic changes.
Pheochromocytomas tend to have different CT imaging features mimicking other tumors according to the size of the tumors. However, clinical features, CT imaging characteristics, and radioisotope activity are not different between small and large pheochromocytomas.
评估小嗜铬细胞瘤与大嗜铬细胞瘤在临床和影像学特征上的差异。
本研究纳入39例肾上腺嗜铬细胞瘤患者。对小嗜铬细胞瘤和大嗜铬细胞瘤的多项临床和影像学特征进行了统计学分析和比较。
两者在临床特征上未发现显著差异。小嗜铬细胞瘤的密度相对更均匀，而大嗜铬细胞瘤有更多的囊性或坏死改变。
嗜铬细胞瘤根据肿瘤大小往往具有不同的CT成像特征，类似其他肿瘤。然而，小嗜铬细胞瘤和大嗜铬细胞瘤在临床特征、CT成像特点及放射性核素活性方面并无差异。
