Sarcoid pyelonephritis is a rare form of kidney inflammation associated with sarcoidosis, a systemic granulomatous disease characterized by the formation of non-caseating granulomas in various organs. In this condition, the kidneys may become involved, leading to pyelonephritis, which is an infection or inflammation of the renal pelvis and kidney tissue. Patients may present with symptoms such as flank pain, fever, and dysuria, although some may be asymptomatic. The diagnosis is often confirmed through imaging studies, such as ultrasound or CT scans, which may reveal renal enlargement or other abnormalities. Laboratory tests may show elevated serum creatinine levels, indicating impaired renal function. The management of sarcoid pyelonephritis typically involves corticosteroids to reduce inflammation and immunosuppressive therapy in more severe cases. Close monitoring of renal function is essential, as the condition can lead to chronic kidney disease if not adequately addressed. Given its association with systemic sarcoidosis, a comprehensive evaluation of the patient’s overall health and potential organ involvement is crucial.
