OBJECTIVE
To report that an unruptured arteriovenous malformation without hydrocephalus may manifest with bilateral optic disk edema and macular exudates.
METHODS
We examined an 11-year-old girl with an unruptured frontal lobe arteriovenous malformation who had decreased visual acuity, bilateral
A case of neurogenic pulmonary edema (NPE) associated with a ruptured spinal cord arteriovenous malformation (AVM) is presented. The mechanisms involved in the development of NPE are discussed briefly. The possible role of preganglionic sympathetic fibers in the spinal cord in the etiology of NPE is
The authors present the case of a 22-year-old man with an unruptured arteriovenous malformation (AVM) in which an intranidal aneurysm had grown in the course of 3 months and was complicated by perifocal brain edema. A left parietal AVM was incidentally diagnosed on magnetic resonance (MR) imaging.
A 16-year-old female patient with headache was admitted to our hospital. Radiological examination showed a Spetzler-Martin Grade III arteriovenous malformation (AVM) located at the left frontal lobe. Volume-staged stereotactic radiosurgery (SRS) treatment performed in two fractions at three-month
We report a case of unruptured arteriovenous malformation in which an extensive zone of increased signal intensity in the brain parenchyma adjacent to the nidus is demonstrated on T2-weighted MR. This area of perilesional hyperintense signal exerts a compressive effect, suggesting that it represents
We report the case of a 27-year-old pregnant woman in whom isolated mild fetal cardiomegaly, diagnosed prenatally on sonographic examination at 22 weeks' menstrual age, was the first sign of development of an arteriovenous malformation of the vein of Galen. The arteriovenous malformation was
It is generally considered that perinidal edema in an arteriovenous malformation (AVM) is caused by a concomitant intracerebral hematoma. We report a rare case of AVM with perinidal massive edema which was possibly not due to hemorrhage, and discuss the pathophysiological mechanisms of such edema
Bilateral thalamic dysfunction secondary to venous congestion may result from either venous sinus thrombosis or high flow arteriovenous malformations or a combination of both. We present a case of bilateral thalamic edema resulting from concomitant choroid plexus arteriovenous malformation (AVM) and
Bilateral thalamic dysfunction secondary to venous congestion may result from either venous sinus thrombosis or high flow arteriovenous malformations or a combination of both. We present a case of bilateral thalamic edema resulting from concomitant choroid plexus arteriovenous malformation (AVM) and
BACKGROUND
Brain edema in unruptured brain arteriovenous malformations (AVMs) is rare; this study examines (1) its frequency and clinical presentation, (2) imaging findings with emphasis on venous drainage abnormalities, and (3) implications of these findings on natural history and
A 29-year-old woman, who had undergone stereotactic radiosurgery for a pontine arteriovenous malformation, experienced sudden onset of facial nerve palsy with trigeminal nerve disturbance 19 months after irradiation. Magnetic resonance imaging revealed significant radiation-induced edema surrounding
Purpose: Today, stereotactic surgery (SRS) is among the treatment options for many intracranial lesions including vascular pathologies. One of the most common late complications of SRS is perilesional edema which can be treated with steroids. In addition to steroids, some new medical
Retinal racemose hemangiomas (RRH) are vascular malformations comprising of direct arteriovenous communications in the retina. Exudation and neurosensory detachment are some of the complications which may cause decreased visual acuity. Herein, we describe a case of a 38-year-old male presenting with
The authors present a case of an arteriovenous malformation of the central sulcus treated with Gamma Knife surgery. The patient developed perilesional edema 9 months after treatment and experienced severe headache and hemiparesis. Her symptoms were refractory to corticosteroid therapy and pain
Brain edema due to venous thrombosis following stereotactic radiosurgery for a cerebral arteriovenous malformation (AVM) has rarely been reported. We report a patient with a large AVM in the eloquent area, and brain edema developed in this area after repeat Gamma knife stereotactic radiosurgery
