ABSTRACT
Pseudokidney sign (PKS) is a characteristic sonographic finding of an abnormal mass with a reniform appearance, and a hyperechoic central region surrounded by a hypoechoic area. It has been seldom documented in gastric cancer. A 75-year-old male patient presented with a palpable abdominal resistance in the left upper abdominal quadrant and ultrasound evaluation revealed a well-vascularized mass presenting with PKS. Regional lymphadenopathy was also found, and the working diagnosis of gastric cancer was established. The suspected diagnosis was later verified endoscopically and on pathohistological examinations as gastric adenocarcinoma. Computed tomography staging also revealed distant metastases to the lungs, liver, and adrenal glands and abdominal lymphadenopathy. The PKS often indicates gastrointestinal pathology, and it may be seen in benign and malignant conditions due to gastrointestinal wall thickening. Therefore, additional diagnostic examinations are advised for a more definite diagnosis.
