Objective: To present 2 cases of Parkes Weber syndrome (PWS) with spinal arteriovenous malformation (AVM) and discuss the radiologic features and clinical treatment with literature review.
Methods: Clinical data on 2 patients with PWS with spinal AVM was acquired in a prospective follow-up investigation. Clinical manifestations, radiographic features, procedural results, and follow-up outcome were collected and reviewed together with a literature review.
Results: The first patient presented with limb weakness and urinary dysfunction and the second with repetitive subarachnoid hemorrhage followed by paraplegia. Limb hypertrophy, skin ulceration, and extensive microfistulas in the affected limb were observed in both patients. Spinal AVM was confirmed by digital subtraction angiography and endovascular embolization was performed. The first patient experienced limb amputation at 6-year follow-up as a result of chronic ulceration and the second did not have neurologic improvement. After literature review, 15 cases (male/female ratio, 5:10; mean age, 22±10.4 years) were included. The presentations comprised subarachnoid hemorrhage in 6, radicular pain in 5, myelopathy in 4, and asymptomatic in 1. Embolization was performed in 9 cases, solitary surgery in 2, and combined therapy in 4. Among 10 cases with known follow-up results, 6 achieved neurologic recovery after surgery and 1 died after solitary surgery.
Conclusions: Awareness of the association between spinal AVM and PWS is essential for radiographic screening of spinal lesions with myelopathy or intracranial subarachnoid hemorrhage. Clinical therapeutic strategy should be multidisciplinary and individualized on the basis of vasculature and lesion behavior.

Aim: A rare and diverse set of abnormalities formed by spinal blood arteries known as spinal arteriovenous malformations (AVMs) has a higher risk of hemorrhage and morbidity, causing the shunting of blood from veins with an aberrant capillary bed to arteries. Knowledge of the vascular anatomy of spinal AVMs and the spinal cord's vascular supply is crucial to its therapy. The aim of this study was to report a case of SAVM healing after surgical excision, highlighting the importance of surgical excision in treating these rare lesions.

Article Synopsis
- * Spinal cord hemangioblastomas make up a small percentage (1.1% to 2.4%) of central nervous system tumors, typically presenting as single tumors in adults around their 40s, while they are rare in children, especially those without VHL syndrome.
- * The thoracic spinal cord is the most common location for these tumors, which can lead to serious symptoms like spinal cord compression and bleeding, despite being classified as benign.

Article Synopsis
- * A 60+ year-old male with HHT type 1 experienced severe back pain and recurrent infections, including a serious case of MSSA bacteraemia and spinal issues, despite previous treatments for infections.
- * The patient was successfully treated with intravenous nafcillin and prescribed cefalexin to prevent future infections, highlighting the need for clearer guidelines on preventive treatment for high-risk HHT patients.

Introduction And Importance: Spinal arteriovenous malformations (AVMs) are a rare condition that has a high risk of bleeding and complications. The authors present the case of a spinal arteriovenous malformation in an unusual location and presentation.
Case Presentation: A 67-year-old man with subarachnoid hemorrhage due to a ruptured spinal arteriovenous malformation type IVa, with associated bulbomedullary aneurysm, which was managed conservatively due to the high risk of complications and mortality.

The present report describes a patient with spinal cord arteriovenous malformation (AVM) and an associated anterior spinal artery aneurysm presenting with subarachnoid hemorrhage. Diagnostic spinal angiography revealed an intramedullary AVM, located at the T10-T11 level, and a prenidal saccular aneurysm at the junction of the radiculomedullary artery and the anterior spinal axis, fed by the right T8 segmental artery. The patient underwent successful selective coil embolization of the aneurysm.
