Two subjects with cerebral embolism were found at autopsy to have marantic (nonbacterial thrombotic) endocarditis (NBTE) and an unsuspected carcinoma. A additional 16 subjects with marantic endocarditis and cancer were found on reviewing the autopsy records of 22 subjects with NBTE. Of these 18 subjects with NBTE and cancer, eight developed a stroke during their illness, in five as the initial manifestation of cancer. Although the association of cancer and marantic endocarditis is generally well recognized, cerebral embolism from this source should be more seriously considered as one of the "remote effects" of cancer on the nervous system.

Nonbacterial thrombotic endocarditis is the most prevalent endocarditis at autopsy. It is a clinically important cause of arterial embolisation. Often it is observed in association with malignancy (mainly gastrointestinal adenocarcinomata), severe infections and other fulminant acute disease processes. A deranged or damaged valvular surface and clotting disorders are important pathogenic factors. The valvular vegetations are pathologically characterized by a bland, fibrin-platelet thrombus; they usually affect the mitral and aortic valve. Neurologic events are the most common clinical manifestations, but any organ may be involved by emboli. The association of venous and arterial thromboses and pulmonary thromboembolism underscores the pathogenetic role of hypercoagulability in the development of nonbacterial thrombotic endocarditis. The clinician must be a vigilant observer in order to make the antemortem diagnosis. If possible, the underlying process should be treated; anticoagulation therapy with heparin sometimes is helpful.

Nonbacterial thrombotic endocarditis is an uncommon, but well-described, complication of bone marrow transplantation. We describe a case of nonbacterial thrombotic endocarditis following autologous bone marrow transplantation that was marked by weight gain, hepatomegaly, ascites, and extreme hyperbilirubinemia leading to a clinical diagnosis of hepatic veno-occlusive disease. Autopsy revealed nonbacterial thrombotic endocarditis of the tricuspid and pulmonic valves, and passive congestion of the liver, but there was no evidence of veno-occlusive disease. We discuss the pathophysiology and clinical features of nonbacterial thrombotic endocarditis and review its occurrence in association with bone marrow transplantation. Nonbacterial thrombotic endocarditis is often difficult to detect clinically and should be a diagnostic consideration in patients who develop systemic emboli or congestive heart failure after bone marrow transplantation.

Nonbacterial thrombotic endocarditis is the most common form of endocarditis found at autopsy. Systemic embolization may complicate this condition in patients with mitral valve prolapse. The authors report a case of mitral valve prolapse and nonbacterial thrombotic endocarditis in which the presenting feature was Parinaud's syndrome.

This paper details the simultaneous occurrence of a severe leukemoid reaction, non-bacterial thrombotic endocarditis (NBTE) (marantic endocarditis), and a consumptive thrombocytopathy without signs of micro-angiopathic hemolysis on peripheral blood smear in a patient with terminal metastatic, undifferentiated, large cell bronchogenic carcinoma. The case is presented and the condition is discussed in detail.

Sudden neurological deterioration suggesting embolism in a patient with a history of cancer should alert the physician to the possibility of a non-metastatic, and therefore potentially reversible, cause of cerebral embolism before cerebral metastasis is implicated. During a four year period, we have observed eight cases of acute cerebral embolism among 3000 cancer patients seen in a department of medical oncology. Five patients had features post mortem of non-bacterial thrombotic endocarditis, and in one, the diagnosis had been made antemortem, but treatment with heparin did not prevent further emboli. Two patients had radiation related carotid vascular disease, and one patient post lymphangiographic embolism. The literature reporting these uncommon causes of cerebral embolism is reviewed. Post-lymphangiographic embolism carries a uniformly good prognosis. In selected cases of post-irradiation cerebral embolism, surgical intervention may prevent a neurological catastrophe. Non-bacterial thrombotic endocarditis and mucin embolism are of uncertain aetiology and natural history; long-term survival is uncommon, and treatment does not appear to influence the clinical course or outcome.

Non-bacterial thrombotic endocarditis (NBTE) was frequently identified in early post-mortem studies of patients with HIV infection, but has not been reported since 1989. The reason for this apparent decline is not clear, but it is possible that the prevalence of the condition was overestimated in the past. We have found no evidence of NBTE in our series of 110 autopsies on subjects from all major risk groups and at various stages of immune deficiency [intravenous drug user (IVDU)-AIDS 35% (39/110), IVDU-pre AIDS 36% (40/110), homosexual-AIDS 25% (28/110), blood product recipients-AIDS 1.8% 2/110), African 0.9% (1/110)]. Infective endocarditis (IE) in HIV infection occurs almost exclusively in intravenous drug users and is rare in other HIV-positive patients. However, asymptomatic HIV infection appears to have little effect on the susceptibility to or the mortality from endocarditis and it is, therefore, appropriate to institute antimicrobial treatment in these cases. The majority (54.4%) of the 960 HIV-positive individuals in the Lothian region of Scotland are young adults who contracted the virus through IVDU around 1983. However, a prospective echocardiological study of 269 patients over four years (IVDU 69%, homosexual 18%, heterosexual 8%, bisexual 3%, multiple risk factors 1%) has demonstrated only four cases of infective endocarditis. We believe this reflects the prevalence of current parenteral drug use in our cohort which has fallen with the introduction of an oral drug replacement programme.(ABSTRACT TRUNCATED AT 250 WORDS)

A fifty-four-year-old woman died from multiple brain infarction and hemorrhage in the bilateral cerebrum, cerebellum, and brainstem, with renal infarction. She developed hematuria and transient blindness sixteen days before admission. Low-grade fever, heart murmur, and aortic valve vegetation on ultrasonic cardiography suggested infectious endocarditis. Autopsy study revealed occult adenocarcinoma in the lung and nonbacterial thrombotic endocarditis, but infective endocarditis was not histologically confirmed. The patient was considered to be a rare case of nonbacterial thrombotic endocarditis who developed multiple small infarctions mainly in the brainstem and cerebellum. Nonbacterial thrombotic endocarditis seems to be still an important disease as the embolic source, even if cryptic, of systemic thromboembolism.

A descriptive term nonbacterial thrombotic endocarditis (NBTE) is used currently instead of the former name marantic endocarditis. The study describes 171 cases of NBTE encountered in autopsies over a period of 22 years (an incidence of 0.93% in adults). Malignancy was present in 59% of cases. Tumors relatively most frequently associated with NBTE were carcinomas of the ovaries, biliary system, pancreas, lung, and stomach. The vegetations were located mostly on the left-sided valves (mitral 64%, aortic 24%, both 9%). The involved valves were otherwise normal in 82%, and they were previously damaged in 18%. Systemic emboli from valvular vegetations occurred in 41% of patients, with splenic, cerebral, and renal circulations being most frequently affected. Pulmonary embolism was noted in 43%. The state of nutrition at autopsy was within normal limits in 35%; there was undernourishment or cachexia in 40%, and overweight or obesity in 22% of patients. The main pathogenetic factor in NBTE seems to be a state of hypercoagulation.

Marantic or non-bacterial thrombotic endocarditis is a common complication of terminal malignancy, usually discovered at autopsy. The authors report a case of marantic endocarditis as a presenting sign of pancreatic carcinoma in which the diagnosis was made ante-mortem by transoesophageal echocardiography.
