A case of atypical clinical and imaging manifestations of an intracranial dural arteriovenous fistula (DAVF) is reported. A 53-year-old man presented with orthostatic syncope and tingling of the fingertips of both hands, and the initial imaging findings were interpreted as brainstem mass. A catheter angiogram confirmed the presence of an intracranial DAVF with venous drainage around the brainstem and spinal cord. The lesion was treated by endovascular embolization and the patient remains asymptomatic 9 months after treatment.

D008279 Magnetic Resonance Imaging Non-invasive method of demonstrating internal anatomy based on the principle that atomic nuclei in a strong magnetic field absorb pulses of radiofrequency energy and emit them as radiowaves which can be reconstructed into computerized images. The concept includes proton spin tomographic techniques.

D008526 Medulla Oblongata The lower portion of the BRAIN STEM. It is inferior to the PONS and anterior to the CEREBELLUM. Medulla oblongata serves as a relay station between the brain and the spinal cord, and contains centers for regulating respiratory, vasomotor, cardiac, and reflex activities.

D004621 Embolization, Therapeutic A method of hemostasis utilizing various agents such as Gelfoam, silastic, metal, glass, or plastic pellets, autologous clot, fat, and muscle as emboli. It has been used in the treatment of spinal cord and INTRACRANIAL ARTERIOVENOUS MALFORMATIONS, renal arteriovenous fistulas, gastrointestinal bleeding, epistaxis, hypersplenism, certain highly vascular tumors, traumatic rupture of blood vessels, and control of operative hemorrhage.

D015901 Angiography, Digital Subtraction A method of delineating blood vessels by subtracting a tissue background image from an image of tissue plus intravascular contrast material that attenuates the X-ray photons. The background image is determined from a digitized image taken a few moments before injection of the contrast material. The resulting angiogram is a high-contrast image of the vessel. This subtraction technique allows extraction of a high-intensity signal from the superimposed background information. The image is thus the result of the differential absorption of X-rays by different tissues. Digital Subtraction Angiography,Subtraction Angiography, Digital
