Vascular anomalies represent a diverse group of tumors and malformations. Those involving the colon and rectum can greatly impact patients' quality of life. Proper workup to ensure the correct diagnosis can vary and may include endoscopic and radiographic studies. These lesions can also be challenging to treat and often require a multidisciplinary approach to ensure the best possible outcome. Treatment can include medical therapy, sclerotherapy, endoscopic, and operative intervention. Many patients will require multimodal therapy. We discuss the workup and management of vascular lesions of the colon and rectum.

A 54-year-old man presented with gait disturbances, urinary incontinence, and headache for 6 months. Head computed tomography indicated several high-density mass lesions in the quadrigeminal cistern, causing occlusive hydrocephalus. Digital subtraction angiography confirmed tentorial dural arteriovenous fistulae (AVF).

Kaposiform lymphangiomatosis (KLA) is a rare and aggressive subtype of complex lymphatic anomalies (CLA), characterized by abnormal lymphatic proliferation leading to distinct clinical manifestations. Despite the complexity of this condition, there is no established standard therapy, and treatment options such as sclerotherapy, laser therapy, and surgery remain variably effective and are limited to symptom management rather than curative. Sirolimus, an mTOR pathway inhibitor, has shown promise as a primary therapy, particularly in patients without a driver mutation.

This study discusses disseminated intravascular coagulation (DIC) associated with solid cancers and various vascular abnormalities, both of which generally exhibit chronic DIC patterns. Solid cancers are among the most significant underlying diseases that induce DIC. However, the severity, bleeding tendency, and progression of DIC vary considerably depending on the type and stage of the cancer, making generalization difficult.

Cerebral arteriovenous malformations (AVMs) are tangles of abnormal vessels with early arteriovenous (AV) shunting that can lead to intracerebral hemorrhage, seizures, neurologic deficit, or headache. To date, only a few cases of carcinomas metastasizing to pre-existing cerebral AVMs have been reported in the literature. However, renal clear cell carcinoma (RCC) brain metastases that exhibit early AV shunting, where AVM pathology is not present, are extremely rare.

Background: The study focuses on vascular compression of the main bronchus in the aortopulmonary space, examining potential contributors within the same axial plane. Its goal is to uncover mechanisms of bronchial compression in patients with intracardiac anomalies and review surgical outcomes, aiming to enhance future results.
Methods: The morphology and topology of structures within the axial plane of the aortopulmonary space were objectively analyzed, including the sternum, ascending aorta, heart, pulmonary artery, descending aorta, and other relevant elements.
