Summary
This study reports the first documented case of cardiac cavernous hemangioma coexisting with multiple pulmonary cavernous hemangiomas, highlighting a rare vascular anomaly in both the heart and lungs.
Area of Science:
- Cardiovascular Pathology
- Pulmonary Medicine
- Oncology
Background:
- Cavernous hemangiomas are benign vascular tumors typically found in the liver or skin.
- Cardiac and pulmonary cavernous hemangiomas are exceptionally rare, with limited case reports.
Observation:
- A patient presented with symptoms suggestive of cardiac and pulmonary disease.
- Imaging studies revealed bilateral pulmonary nodules, pericardial effusion, and a pericardial neoplasm.
- Pathological examination confirmed large, blood-filled vascular spaces consistent with cavernous hemangiomas in both the heart and lungs.
Findings:
- The cardiac tumor and pulmonary nodules exhibited characteristic features of cavernous hemangiomas.
- Immunohistochemical markers (CD31, FLI1, FVIII, CD34) confirmed endothelial cell origin.
- This represents the first reported instance of coexisting cardiac and multiple pulmonary cavernous hemangiomas.
Implications:
- This case expands the known spectrum of cavernous hemangioma presentation.
- Highlights the importance of considering rare vascular tumors in differential diagnoses for cardiac and pulmonary lesions.
- Further research may elucidate the underlying mechanisms and potential genetic factors of multifocal cavernous hemangiomas.

805
Hypertrophic cardiomyopathy, or HCM, is an autosomal dominant genetic disorder characterized by asymmetric left ventricular hypertrophy without ventricular dilation. It is more common in men and is typically diagnosed in young, athletic adults.EtiologyHCM is primarily genetic and is caused by mutations in genes encoding sarcomeric proteins. Researchers have identified over 1400 mutations across at least 11 different genes. Among these, the most frequently occurring mutations are found in the...

01:22Portal Hypertension
50
Portal hypertension is an increase in blood pressure within the portal venous system. Normally, this pressure is less than 5 mmHg. It is considered clinically significant when it rises above 10 mmHg. At this threshold, complications from altered blood flow and venous congestion emerge.EtiologyPortal hypertension arises from conditions that impede blood flow through the liver. The most common cause is cirrhosis, in which chronic liver injury leads to fibrotic scarring. This fibrosis narrows or...

826
Cardiomyopathy, or CMP, is a group of diseases affecting the myocardial structure, impairing its ability to pump blood effectively. This condition can lead to arrhythmias, heart failure, or sudden cardiac death.Cardiomyopathies are classified into primary and secondary categories:Primary Cardiomyopathy refers to conditions involving only the heart muscle that are often idiopathic (of unknown cause) or genetic. They primarily affect the myocardium without the involvement of other systemic...

01:23Mitral Stenosis II: Clinical features and Diagnostic Tests
557
Mitral stenosis is a heart condition in which the mitral valve, which allows blood to flow from the left atrium to the left ventricle, becomes narrowed or stenotic. This narrowing hinders blood flow and leads to clinical symptoms requiring specific medical evaluations and management strategies. The following overview outlines the clinical symptoms, assessments, diagnostic findings, prevention methods, and treatments for mitral stenosis.Clinical ManifestationsDyspnea (shortness of breath): This...

906
Pulmonary hypertension (PH) is a severe health condition in which the mean pulmonary arterial pressure increases to 25 mmHg or more, even when the body is at rest. This high pressure in the blood vessels that transport blood from the heart to the lungs can cause various symptoms, including shortness of breath, can lead to right heart failure, and significantly affect the overall quality of life.
There are various classifications for PH, each relating to different underlying causes and also...

790
Dilated cardiomyopathy, or DCM, is a progressive myocardial disorder characterized by ventricular chamber dilation and contractile dysfunction.EtiologyVarious factors can cause DCM, including hypertension and heavy alcohol intake, which contribute to the weakening and enlargement of the heart muscle. Viral infections, such as Coxsackievirus B, adenoviruses, and influenza, can lead to DCM by causing inflammation and damage to heart tissue. Certain chemotherapeutic agents, including daunorubicin,...
