A 46-year-old man presented to the internal medicine department with a 1-year history of abdominal pain. His medical history was non-obstructive hypertrophic cardiomyopathy. Physical examination was unremarkable. As part of the evaluation, computed tomography of abdomen was performed. Focused assessment with computed tomography confirmed no evidence of ascites, but the left kidney could not be identified. A whole-body computed tomography discovered a pelvic left kidney (Figure 1A). Renal function of the patient was normal with a creatinine level of 0.89 mg per deciliter (77 µmol per liter) (normal range, 0.5 to 1.1 mg per deciliter [48 to 90 µmol per liter]). It is a common incidental finding because the affected persons are commonly asymptomatic. Renal ectopia is commonly caused by failure of mature kidney to reach its natural location in renal fossa
