Segmental infarction of the kidney upper pole as cause of acute back pain.

Renal infarction is a rare condition often misdiagnosed as more common renal disorders due to similar symptoms. This case report highlights a 52-year-old patient who presented with severe lumbago and was diagnosed with segmental renal infarction in the upper pole of the left kidney. The patient's clinical course, diagnostic evaluation, and multidisciplinary management are described. The importance of early diagnosis through imaging techniques, such as computed tomography, is emphasized. Treatment strategies, including anticoagulation and pain management, are discussed. This case underscores the need for a high index of suspicion to ensure timely diagnosis and appropriate management of renal infarction.
