Sarcoidosis presenting with hearing loss and granulomatous interstitial nephritis in an adolescent

Abstract: Granulomatous interstitial nephritis is an uncommon finding in a kidney biopsy. The differential diagnosis is broad and includes infections, drug exposure, and sarcoidosis. Sarcoidosis, a systemic disorder of unknown etiology characterized by the presence of noncaseating granulomata in affected organs, is rare in children. We discuss an adolescent boy with the unusual presentation of granulomatous interstitial nephritis and acute deafness. Sarcoidosis should be considered as part of the differential diagnosis … Show more

“…While granulomas appear to be the exception in cases of TINU, they are the defining lesion in sarcoidosis. Sarcoidosis commonly affects the eye, and approximately 20% of patients with systemic sarcoidosis will develop granulomatous interstitial nephritis [25,26]. Thus when biopsies identify renal granulomas, and particularly if there is evidence of other systemic granulomatous disease, sarcoidosis rather than TINU is the preferred diagnosis.…”

“…For example, another recent case report of a 22 year-old male with a bilateral, granulomatous, and hypertensive anterior uveitis, resulted in the diagnosis of TINU despite the presence of numerous non-caseating granulomas associated with interstitial nephritis on renal biopsy [28]. These cases highlight two important points: TINU is a diagnosis of exclusion, and that renal biopsy can help provide diagnostic clarity in challenging cases [26,29,30]. …”

“…After multiple debates, the question that nephrocalcinosis and/or GIN might have a better prognosis remains uncertain. In Table S1 , we have summarized all the studies of sarcoidosis with renal involvement in children that were the basis of this review [ 53 , 54 , 55 , 56 , 57 , 58 , 59 , 60 , 61 , 62 , 63 , 64 , 65 , 66 ].…”

“…5 While about 80% to 90% of cases of neurosarcoidosis involve the cranial nerves, the presentation of sudden hearing loss has been reported in about 30 pediatric cases in the reviewed literature. 6,7 This presentation can be very insidious; however, the clinician should have a low threshold for suspicion for an autoimmune disease so that appropriate immunosuppressive therapy can be initiated early in the course of disease. As in systemic disease, corticosteroid therapy can decrease the inflammation and thus reverse the hearing loss.…”
