RESUMO
BACKGROUND: Surgical procedures may alter normal anatomy, confounding the interpretation of cross-sectional imaging studies. This problem is greater if neither a relevant history nor previous comparison studies are available. CASE OUTLINE: In a 29-year-old woman submitted to radical hysterectomy for cervical carcinoma, one ovary was surgically repositioned into the right paracolic gutter out of the radiation field. This ovary simulated a hepatic metastasis on subsequent CT examinations. History was obscure, adding to the interpretive challenge. DISCUSSION: Clues to establishing the correct diagnosis are presented. The availability of an adequate history and previous radiological images are important to prevent diagnostic error.

A patient had both the clinical presentations and the ventilation-perfusion scan that simulated pulmonary embolism so closely that anticoagulant therapy was administered. Computed tomography of the chest and Ga-67 citrate scintigraphy identified hilar adenopathy due to sarcoidosis as the cause of a ventilation-perfusion mismatch.
