Pulmonary micro-tumor emboli resulting in paradoxical emboli: a case report
نویسندگان
چکیده
Pulmonary tumor embolism (PTE) is a rare manifestation of cancer. It is characterized by the presence of tumor cell emboli in the pulmonary arterioles and capillaries leading to an elevation of pulmonary vascular resistance. The ante-mortem diagnosis is difficult. We report a case of PTE associated with recurrent breast cancer that presented with neurological symptoms due to paradoxical cerebral embolism.

Our thorough medical literature search showed only 17 reported cases in the course of pregnancy. Myxomas during pregnancy and in the preterm period constitute a serious phenomenon that can mimic an early sign of a life-threatening pathology like severe ...
متن کاملParadoxical Emboli Secondary to Hepatic Pathology: Common or Coincidental?
Paradoxical cerebral emboli from cardiac and pulmonary sources are well described in the peer-reviewed literature. We outline a case with a hepatic etiology and describe diagnostic and management options. Though this paper represents the first documentation of such, we believe that transpulmonary shunting with concurrent paradoxical cerebral microemboli is more prevalent than recognized. We int...

Background & Aims: The most common diagnostic modality for pulmonary emboli is CT angiography (CTA). Because of the availability and inexpensiveness, taking an electrocardiogram (ECG) is the first step in patients suspicious to pulmonary emboli. However, ECG does not provide any sensitive or specific manifestations for diagnosis of pulmonary emboli. We aim to evaluate the correlation between...
متن کاملPulmonary tumor embolism as an initial manifestation of pancreatic adenocarcinoma.
Pulmonary tumor embolism is a rare syndrome caused by migration of tumoral emboli into the pulmonary arteries. These tumor emboli may form a fibrin-platelet thrombi, resulting in pulmonary-artery hypertension and subsequent right-heart failure. Establishing this diagnosis can be very difficult, and most cases are diagnosed during autopsy,1 although a history of cancer may be a predictor. We rep...

Esophageal perforation is one of the most lethal forms of mediastinitis that usually named as disaster, denoting its lethality. The most important factor in patient salvage is early diagnosis. Post emetic rupture or Boerhaaves syndrome is accounted for 10-15 percent of causes. Unfortunately due to its rarity, usually is misdiagnosed as other equally serious but more prevalent pathologies such ...
