Bilateral Spontaneous Perirenal Hemorrhage due to Initial Presentation of Polyarteritis Nodosa

Abstract

Spontaneous perirenal hemorrhage (SPH) is uncommon but can be a life-threatening condition which is associated with flank or abdominal pain and hypovolemia. The etiologies of SPH include tumor, vascular disease, and infection. Among the vascular diseases, polyarteritis nodosa (PAN) is common cause of the SPH. However, patients with PAN usually complain of nonspecific symptoms and the incidence of PAN is relatively rare. So, diagnosis is difficult even though tissue biopsy and angiography help to confirm the PAN. Particularly bilateral perirenal hemorrhage is very rare complication in patients with PAN. We reported a case of bilateral perirenal hemorrhage in the patients with PAN who have continued to take exogenous sex hormone.

Spontaneous perirenal hemorrhage in a pregnant woman due to the rupture of a simple renal cyst

“…Simple renal cysts are the most common cystic lesions found in adults and may be symptomatic at any time (3). Cysts are incidentally discovered in children and adults by ultrasonography, CT scan, or urography (4), but can be formed after abdominal mass pain, hematuria secondary to rupture into the pyelocalyceal system, segmental ischemia, and following spontaneous perinatal hemorrhage (SPH) in rare cases (5).…”

Spontaneous bilateral perirenal and splenic haematoma in childhood onset polyarteritis nodosa

“…In 1908, Schmidt4 first described perirenal haematoma by ruptured of microaneurysm in PAN. In a meta-analysis, only five cases of perirenal haematoma due to PAN has been described 1 5 6…”
