Pulmonary tumor thrombotic microangiopathy (PTTM) is a rare but fatal complication of cancer and causes pulmonary hypertension and acute/subacute right heart failure. PTTM is most commonly associated with gastric cancer and more rarely associated with pancreatic cancer. We report a case of progressive right heart failure associated with clinically diagnosed pancreatic cancer, suggesting PTTM.
Mid-aortic syndrome (MAS) is a rare condition characterized by stenosis of the distal thoracic and/or abdominal aorta. Williams-Beuren syndrome (WBS) is a relatively rare cause of MAS. We report a case of incidentally diagnosed MAS caused by WBS without typical manifestations caused by an atypical small-sized deletion in chromosome 7q11.23, which was initially misdiagnosed as Takayasu arteritis.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
