Abstract
Acute renal infarction usually occurs in patients with severe atherosclerosis or valvular heart disease. We here report a 42-year Saudi male who presented with severe abdominal pain nausea and vomiting associated with hematuria, after heavy smoking of marijuana. Computed tomography abdomen revealed bilateral renal infarction. Serum anti phospholipids antibody and anti-cardio lipid antibody were positive. To the best of our knowledge, the association between marijuana and secondary lupus anticoagulant-induced renal infarction has not been reported previously.
