Melanoma to the heart - PMC
Magnetic resonance imaging (MRI) of the brain and spine revealed a mass on the conus medullaris and multiple intraparenchymal lesions in the cerebral hemispheres bilaterally. Computed tomography (CT) of the chest, abdomen, and pelvis performed for staging purposes demonstrated an intracardiac mass (Figure).
Cardiac Metastatic Melanoma Investigated by Magnetic …
1998年1月1日 · This report describes four cases with different clinical presentations of MM cardiac involvement that were investigated by magnetic resonance imaging (MRI). The MM cardiac involvement was asymptomatic in one case, detected because of a superior vena cava syndrome in a second, and because a tamponade in the remaining two cases.
Metastatic melanoma of the heart: A systematic review.
2020年5月25日 · Background: Melanomas are highly aggressive tumors that can metastasize to a wide array of organs, including the heart. Cardiac metastasis is rare and most often diagnosed post-mortem. Here, we perform a systematic review evaluating patient demographics, characteristics, management, and outcomes of cardiac melanoma metastases.
Metastatic Melanoma to the Heart - ScienceDirect
2012年9月1日 · Melanoma is a common neoplasm with a propensity to metastasize to the heart. Although cardiac metastasis is rarely diagnosed ante mortem, using a multimodality approach, several imaging findings may be seen. Echocardiography is often the initial imaging method used to detect cardiac metastases and their complications.
Cardiac metastases of melanoma as first manifestation of the …
Findings on MRI imaging: T1w, T2w and LGE sequences: anatomic definition and tissue characterization. Cine sequences: functional impact. We expect melanoma to be T1 hyperintense and T2 hypointense, but only a small percentage of melanoma metastasis have these classic findings. Amelanotic melanoma may be T1 iso- and hypo-intense
MYOCARDIAL METASTATIC MELANOMA - Journal of the …
Cardiac MRI was pursued due its ability to provide detailed tissue characterization, revealing two thrombi in the right atrium, thrombus on the tricuspid valve, bright T1 tissue measuring 40x23mm above the anterior wall of the LV (D), and a hyperintense mass on the RV free wall (E) consistent with metastatic melanoma.
Cardiac metastatic melanoma: Imaging diagnostic clues
2015年8月1日 · Cardiac metastases often remain silent, being an autoptic finding; when symptomatic they can mimic all forms of cardiac disease, ranging from dyspnea, to atrial and ventricular arrhythmias, to chest pain, and represent an insidious diagnostic challenge. Melanoma is the solid tumor with the highest propensity to hematogenous spread to the heart.

2005年9月9日 · Magnetic resonance imaging (MRI) was performed and revealed a large oval mass emanating from the anteroseptal wall of the left ventricle within the apex. On fat-suppressed double inversion recovery imaging (c), the left ventricular mass was noted to have homogeneous bright signal consistent with a malignant melanoma metastasis. Although the ...
Imaging characteristics of cardiac metastases in patients with ...
2017年7月1日 · While malignant melanoma frequently involves the heart, the diagnosis of cardiac metastases is often late due to the lack of specific clinical signs and limited sensitivity of routine cardiac examinations . Follow up-imaging of malignant melanoma is important for the assessment of therapy response and for the detection of new metastases ...
