Background: Crossed fused renal ectopia (CFRE) is a common congenital anomaly where one kidney is positioned abnormally on the opposite side of the midline, often fused with the other kidney. However, single ureter draining crossed fused renal ectopia is a rare occurrence.
Case Report: Here, we report a case of crossed fused renal ectopia with a single ureter in a 46-year-old Nepali male who presented with history of lithuria.
Key Clinical Message: Foreign body aspiration is common in old age, sometimes lodged in unusual locations like the left upper lobe bronchus when aspiration happens in a recumbent position. Computed tomography is the preferred diagnostic tool, while flexible bronchoscopy is effective for removing the foreign body.
Abstract: Tracheo-bronchial foreign body aspiration (FBA) is common in children and elderly, but often goes unnoticed due to vague symptoms and atypical imaging findings.
