A Cavrnous Hemangioma is an abnormal tangle of tightly packed thin walled capillaries that are probe to bleeding.

Sclerosing hemangioma of the lung is a rare and mostly benign lung tumor, which affects especially Asian middle-age women (median age of 48 years). We report the case of a 27-year-old woman in which, a premarital routine chest X-ray investigation revealed a 2 cm well-defined opaque nodule in the lower left pulmonary lobe, confirmed by CT scan. Microscopically, the surgically enucleoresected nod...

Background: Intracranial capillary hemangiomas are rare, particularly in adults, and diagnosis can be challenging. The literature lacks visualization of intracranial hemangioma growth over time. Here we document a de novo hemangioma, initially interpreted radiologically as glioma. Methods: We report case 64 year old male with history HIV, recent Lyme disease unconfirmed prior COVID-19 infection...

OBJECTIVE The mechanism of neovascularization during the proliferative phase of infantile hemangioma is poorly understood. It is known that circulating bone marrow-derived endothelial progenitor cells (EPCs) form new blood vessels in ischemic tissues using mediators regulated by the transcription factor, HIF-1alpha. Mobilization of EPCs is enhanced by VEGF-A, matrix metalloproteinase (MMP)-9, a...

With the advent of high-resolution CT, criteria for the diagnosis of intraspinal hemangiomas have been established . These consist of the presence of intracanalicular soft-tissue masses of mild to moderately hyperdense attenuation with variable degrees of contrast enhancement, primarily in association with vertebral hemangioma [1-6]. The presence of calcification in the intraspinal soft-tissue ...

In infants, the embolization of liver hemangiomas with congestive heart failure demonstrates therapeutic efficiency by the rapid resolution of heart failure. This is because of the collaterals between the hepatic artery and the hepatic veins. In adults, heart failure due to a giant hemangioma is very rare and the most common indication in adults is a kind of pain in the trunk. The expectation f...

A 48-year-old man presented with a 2-week history of progressive gait disturbance. Neurological examinations showed mild weakness in his lower extremities and depreciation of deep sensation. Magnetic resonance (MR) imaging showed an intradural extramedullary enhanced lesion at the levels of the T10 and T11 vertebrae. Laminectomy of the T10 and T11 vertebrae was performed, and the vascular tumor...

Infantile hemangiomas are composed of endothelial cells (ECs), endothelial progenitor cells (EPCs), as well as perivascular and hematopoietic cells. Our hypothesis is that hemangioma-derived EPCs (HemEPCs) differentiate into the mature ECs that comprise the major compartment of the tumor. To test this, we isolated EPCs (CD133 /Ulex europeus– I ) and mature ECs (CD133 /Ulex europeus– I ) from pr...

We present a case of cardiac capillary hemangioma in a patient who presented with a history of recurrent episodes of syncope. Cardiovascular magnetic resonance played an important role in the diagnosis of cardiac hemangioma in our patient.

Hemangioma of the azygos venous arch is an exceedingly rare incident. This is a case of a thoracoscopic complete resection of a hemangioma of the azygos venous arch in a 37-year-old woman.
