Right ventricular thrombus in Wegner's granulomatosis

A 14 year-old boy presented with frank haematuria following two weeks of fever, coryzal symptoms and epistaxis. Renal biopsy and serology confirmed Wegner’s granulomatosis. This case illustrates the need for vigilance for signs of thrombosis in children with Wegner’s granulomatosis, particularly in those with additional risk factors such as heavy proteinuria, reduced mobility and an indwelling central venous catheter.
