IntroductionThe occurrence of pulmonary artery dissection is extremely rare in patients without pulmonary hypertension, congenital cardiac abnormalities or cardiac intervention. A diagnosis of pulmonary artery dissection is rarely made during life because it generally leads to cardiogenic shock and sudden death. The progression or natural course of pulmonary artery dissection is not known and the optimum management is not defined because of the paucity of cases in the literature.Case presentationWe report a rare case of a 51-year-old female patient, without pulmonary hypertension or other cardiac abnormalities, who presented with acute chest pain and was found to have a pulmonary artery dissection.. The diagnosis of pulmonary artery dissection was confirmed by computed tomography scan of the chest and cardiac magnetic resonance imaging. The patient declined surgical intervention and was followed up closely with medical therapy. At almost a year after her initial presentation, the patient is stable with no complications.ConclusionsTo our knowledge, there are no similar cases reported in the literature of people with pulmonary artery dissection who have been followed up and who have not had surgical intervention. We review the etiology, pathophysiology, clinical associations, diagnosis and management of patients with pulmonary artery dissection.

Three cases of portal venous system wall calcifications demonstrated by computed tomography are presented. The clinical features, possible pathogenesis, differential diagnosis, and therapeutic significance of this condition are reviewed.
