|April 29, 2021
Summary
Developmental venous anomalies (DVAs) are usually benign brain variations. Rarely, a DVA alone can cause intracranial hemorrhage, as seen in this case report of a cerebellar DVA with associated hemorrhage and cavernoma.
Area of Science:
- Neurology
- Neuroradiology
- Vascular Neurology
Background:
- Developmental venous anomalies (DVAs) are common, typically benign variations of cerebral venous drainage.
- Isolated DVAs are usually incidental findings and not clinically significant.
- Intracranial hemorrhage from an isolated DVA is a rare occurrence.
Observation:
- A 58-year-old woman presented with cerebellar syndrome.
- Imaging revealed a cerebellar DVA and associated intracranial hemorrhage.
- Follow-up imaging demonstrated an additional cavernoma.
Findings:
- The case presents a rare instance of intracranial hemorrhage attributed solely to a developmental venous anomaly.
- The co-occurrence of a DVA and a cavernoma was noted.
- Conservative management was chosen for the patient.
Implications:
- This case underscores the potential, albeit rare, for DVAs to cause significant intracranial hemorrhage.
- It highlights the importance of thorough neuroimaging evaluation in suspected DVA-related hemorrhages.
- Further research into DVA-associated pathologies and hemorrhage risk is warranted.

01:19Veins of Head and Neck
3.8K
The blood drainage from the head and neck is primarily managed by three pairs of veins: the external jugular, internal jugular, and vertebral veins. The external jugular veins drain superficial scalp and face structures, passing over the sternocleidomastoid muscles to empty into the subclavian veins.
On the other hand, the vertebral veins, unlike their arterial counterparts, are not primarily responsible for brain drainage. Instead, they drain the cervical vertebrae, spinal cord, and some small...

01:20Venous Thrombosis II: Clinical Manifestations and Diagnostic Studies
90
The key difference between Superficial Vein Thrombosis (SVT) and Deep Vein Thrombosis (DVT) lies in their location and severity.Clinical ManifestationsSVT typically presents with localized pain, tenderness, and redness along the course of a superficial vein, often accompanied by a palpable, cord-like structure under the skin. This condition is usually less dangerous than DVT but can be uncomfortable and may lead to complications such as cellulitis or, rarely, a clot extension into the deep...

01:18Anatomy of the Brain: Ventricles
6.1K
There are hollow fluid-filled cavities known as ventricles deep inside the human brain. There are two lateral ventricles, one in each cerebral hemisphere, and each has three different projections — the anterior, inferior, and posterior horns visible from the lateral side. A thin membrane called the septum pellucidum separates the two lateral ventricles. The slender third ventricle in the diencephalon is connected to each lateral ventricle via a channel called the interventricular foramen.

103
Venous thrombosis, the most common disorder of the veins, involves the formation of a thrombus or blood clot associated with vein inflammation. It can be classified as either superficial vein thrombosis or deep vein thrombosis.Superficial Vein Thrombosis: This involves the formation of a thrombus in a superficial vein, usually the greater or lesser saphenous vein. Though less severe than deep vein thrombosis (DVT), SVT can lead to complications if untreated.Deep Vein Thrombosis (DVT): This...

01:24Esophageal Varices-I: Introduction
584
Esophageal varices are dilated, tortuous veins which are found mainly in the submucosa of the lower esophagus but which may also appear higher up or extend into the stomach. They develop due to increased pressure in the portal venous system, often as a result of liver cirrhosis. This condition scars and damages the liver, impeding normal blood flow through the portal vein. To compensate, blood seeks alternative pathways, forming fragile new vessels (varices) in the esophagus and stomach. These...

01:10The Arch of Aorta
1.2K
The coronary arteries, originating from the ascending aorta, bifurcate from two sinuses located within the ascending aorta. Positioned just above the aortic semilunar valve, these sinuses house essential aortic baroreceptors and chemoreceptors, crucial for maintaining cardiac function. The left coronary artery and the right coronary artery branch off from the left posterior and anterior aortic sinuses, respectively.
