Abstract:
BACKGROUND:Testicular microlithiasis (TM) is characterized by calcium deposits within the seminiferous tubules and is associated with benign and malign conditions. AIM:To determine TM prevalence in patients with congenital adrenal hyperplasia (CAH) and its association with testicular adrenal rest tumors (TART). PATIENTS AND METHODS:Scrotal ultrasound using a high-frequency linear transducer (12 MHz) was performed in 41 patients aged 12.1 +/- 4.7 (range 3.5-23.3) years and 49 healthy similarly aged controls. TM was classified with respect to the number of microliths per ultrasound field as limited (LTM, <5 microliths) and classic (CTM, > or = 5 microliths). CTM was graded as grade 1 (5-10 microliths), grade 2 (11-20 microliths), and grade 3 (>20 microliths). RESULTS:TM was detected bilaterally in 9 (21.9%) patients and 2 (4.1%) control cases (1 bilateral, 1 unilateral). Four patients had LTM, one evaluated as grade 1, one as grade 2, and three as grade 3. There were 9 patients with TART. Four patients had TM and TART concomitantly. CONCLUSION:Because TM is frequently found in patients with CAH and may also exist concomitantly with TART, we recommend that these patients be followed annually by testicular ultrasound.
