An unusual presentation of polyarteritis nodosa: A case report.

Polyarteritis nodosa with gallbladder involvement is a rare condition. Autosomal dominant polycystic kidney disease is also a rare condition and rarely complicated. We describe an extremely rare case of Polyarteritis nodosa, involving gallblader and ureter without obstruction, in a patient with autosomal dominant polycystic kidney disease. To the best of the authors' knowledge, such a case has not been reported previously.
