Three cases of intracerebral venous angioma, a rare vascular malformation, were studied by radionuclide brain scan, transmission computed tomography (TCT) and angiography. In each case, the radionuclide flow study demonstrated a typical area of abnormal increase in activity during the venous phase; in two of the cases the arterial phase was also abnormal. Each contrast angiogram demonstrated a normal arterial distribution and a characteristic network of abnormal veins that converged to a large transcerebral draining vein. The TCT scans showed enhancing, curvilinear densities; while not specific, this finding should suggest the possibility of venous angioma in the brain.

Background: Blue rubber bleb nevus syndrome (BRBNS) is a rare venous malformation disorder. Currently, there is no standard therapy for this disease. However, lauromacrogol, a sclerosant extensively utilized in the management of vascular malformations, has been applied in the treatment of BRBNS.

Arteriovenous Malformations (AVM) can present themselves in an ample clinical spectrum. They worsen over time, creating local complications such as ulceration, destruction, infection, pain, and severe bleeding. Small focal AVMs can effectively be cured by surgery and/or endovascular techniques, whereas larger ones are of difficult management.

Fetal and neonatal cardiac tumors are rare and often benign. Clinical presentation is primarily related to mass effect, pericardial effusion or arrhythmia. Prenatal detection can assist with risk assessment and inform optimal delivery plan and postnatal management.

Background: Cavernous hemangiomas can occur in various internal organs like the liver, kidney, bladder, and skin, or even in subcutaneous tissues. However, they rarely occur in the lungs, making pulmonary cavernous hemangiomas (PCH) an uncommon finding. Herein, we report a rare case of pulmonary cavernous hemangioma that was surgically resected.

Vascular anomalies are broadly classified into 2 categories: vascular tumors and vascular malformations. Vascular anomalies frequently present as cutaneous lesions in infants. This review summarizes vascular anomalies that most commonly present as dermatologic lesions in the neonatal period, with a focus on the clinical findings, pathophysiology and histology, relevant radiographic findings, and management of common vascular anomalies such as infantile hemangiomas, congenital hemangiomas, and Kaposiform hemangioendothelioma, along with vascular malformations, including capillary, lymphatic, venous, and arteriovenous malformations.
