Abstract

Solid pseudopapillary tumor (SPT) is a rare low-grade malignant neoplasm originating predominantly in the pancreas. Extra-pancreatic SPTs are exceedingly rare clinical entities. The 18 F-FDG PET/CT imaging features of extra-pancreatic SPTs remain poorly characterized in the current literature. We present a diagnostically challenging case of left adrenal SPT demonstrating MRI and 18 F-FDG PET/CT features indistinguishable from adrenocortical carcinoma, ultimately resulting in preoperative misdiagnosis.

模拟肾上腺皮质癌的实性假乳头状肿瘤的PET/CT表现。

实性假乳头状瘤是一种罕见的低级别恶性肿瘤，主要发源于胰腺。胰腺外spt在临床上极为罕见。在目前的文献中，胰腺外spt的18F-FDG PET/CT成像特征仍然很差。我们报告了一个诊断具有挑战性的左肾上腺SPT病例，其MRI和18F-FDG PET/CT特征与肾上腺皮质癌难以区分，最终导致术前误诊。
