Patient: Female, 39-year-old Final Diagnosis: Intravenous leiomyomatosis Symptoms: Dyspnea • syncope Medication: — Clinical Procedure: — Specialty: Cardiology • Critical Care Medicine • General and Internal Medicine Objective: Rare disease Background: Intravenous leiomyomatosis (IVL) is a rare benign smooth muscle tumor originating in the uterus or in the uterine vessels. It is characterized by continuous intraluminal growth that may extend through iliac veins and inferior vena cava (IVC) to right chambers of the heart and pulmonary vasculature, leading to life-threatening complications. This case report describes an uncommon cause of non-thrombotic pulmonary embolism in young woman caused by extensive IVL. Case Report: A 39-year-old woman was admitted after multiple syncopal episodes. She was initially found to have a bilateral pulmonary embolism and large right atrial mass believed to be a thrombus. After an unsuccessful attempt to remove the thrombus with AngioVac (AngioDynamics, Latham, NY), subsequent sternotomy revealed a large pedunculated mass extending to the infra-hepatic IVC. Further abdominal imaging showed multiple uterine masses, with the largest about 17 cm, infiltrating the parauterine vessels and extending through the right iliac vein and inferior vena cava up to the right atrium. Pathology examination of the atrial mass revealed benign leiomyoma consistent with further pathology findings after hysterectomy. The pulmonary embolism was believed to be caused by tumor tissue, and anticoagulation was abandoned. Pulmonary nodule raised a suspicion of benign pulmonary metastases, but, fortunately, remained stable during follow-up and the patient had a successful recovery. Conclusions: Available information about IVL is scarce. This tumor, although benign and rare, should be included in the differential diagnosis of cardiac tumors and non-thrombotic pulmonary emboli in women with predisposing risk factors, as potential complications are life-threatening.
The use of electronic cigarettes and vaping devices have increased in prevalence since 2007. Aerosolized particles form a vapor by heating a liquid within the device which is then inhaled. Studies of the long term effects of vaping have not been completed due to the novelty of the phenomenon. Known complications include bronchiectasis, eosinophilic pneumonia or hypersensitivity pneumonitis, but rarely is diffuse alveolar hemorrhage (DAH) seen. Here we report a case of a patient with a vaping history admitted for hemoptysis who was found to have DAH.
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.
