Abstrakt:	Objective: To report one case of bilateral kidney pseudotumor due to sarcoidosis in a 75 year-old man with prostatic carcinoma and hypertrophic pachymeningitis. Methods: Renal Doppler, body CT, CT-guided renal biopsy, blood analysis including angiotensin converting enzyme (ACE), blood levels and test-treatment (corticosteroid response) were performed. Results: The radiological studies performed showed bilateral kidney masses and pulmonary calcified hilar adenopathies. Blood analysis showed renal failure and increased ACE levels. Renal biopsy showed non-caseating granulomas. Neurological symptoms and renal failure improved with corticosteroid therapy. Conclusion: Bilateral kidney pseudotumor due to sarcoidosis is a rare pathology. Sarcoidosis must be included in the differential diagnosis work up of patients with inflammatory or autoimmune disease and bilateral kidney pseudotumors. Radiological findings of kidney sarcoidosis are quite unspecific. Histological diagnosis with CT guided biopsy or US guided biopsy of kidney masses may be performed.
