Spontaneous isolated superior mesenteric artery dissection is a very rare vascular disease that involves the superior mesenteric artery or its branches, with an incidence as low as 0.08%. The majority of cases occur in patients of Asian descent. Due to advances in imaging modalities, particularly abdominal computed tomography angiography, the diagnosis of this disease has been increasing. Herein, we present a rare case of spontaneous isolated superior mesenteric artery dissection with thrombosis in a young male patient with no past medical history. The importance of this disease as a differential diagnosis for acute abdominal pain is emphasized., (© 2022 The Authors.)

Hydatid liver disease (HLD) is the most common form of hydatid disease, and it is caused by a zoonotic infection with a tape worm. It is endemic mostly in sheep-farming countries and rare in the United States. Liver involvement is usually asymptomatic, but symptoms develop upon growth of the cyst leading to many complications, most common of which is intra-biliary rupture, and less likely biliary obstruction. Diagnosis is clinical, serologic and radiologic. Therapeutic approaches to HLD include surgery, anthelminthic medications and medico-surgical procedures. Here we present a case of HLD that presented in advanced stage leading to grave consequences, complicated course and difficult therapeutic options. Given the rarity of hydatid disease in Northern America, physicians have to keep high index of suspicion especially in a patient with history of travel to endemic areas, as early diagnosis and treatment is important to avoid high morbidity and mortality., Competing Interests: None to declare., (Copyright 2021, Alameri et al.)
