Reninoma presenting as cardiac syncope.

Tak SI, Wani ML, Khan KA, Alai MS, Shera AH, Ahangar AG, Khan YB - Ann Pediatr Cardiol (2011)

Bottom Line: Reninoma, a renin-secreting tumor of the juxta-glomerular cells of the kidney, is a rare but surgically treatable cause of secondary hypertension in children.We report a case of reninoma presenting as cardiac syncope with long QTc on electrocardiogram due to hypokalemia.

Figure 3: Computed tomography picture showing renal mass lesion

Mentions: Echocardiography revealed concentric left ventricular hypertrophy and mild mitral regurgitation. There was no evidence of left ventricular outflow tract obstructive disease. The patient initially received intravenous magnesium and potassium, nitroglycerine, oral beta blockers and angiotensin receptor antagonists. His QTc normalized, premature ventricular ectopics disappeared, blood pressure got controlled and the patient became asymptomatic. Renal ultrasound Doppler was suggestive of replacement of left kidney by a necrotic mass (5 cm × 4.8 cm), with invasion of the left renal artery with normal vascular flow profile. A contrast enhanced computed tomography scan of the abdomen confirmed a cystic mass replacing the left kidney and compressing the left renal vein, with normal adrenal glands. A differential diagnosis of Bosnaik type IV cyst and Wilm's tumor were considered [Figure 3].
