A case of spinal epidural AVM with unusual clinical course was presented. A 28-year-old male had repeated episodes of paraparesis and complete recovery in several hours. Metrizamide myelography revealed the dorsal epidural mass at the level of L2 and L3. Accidental epidurogram during the procedure indicated extradural angioma. Surgical intervention proved solitary spinal epidural AVM. Ninety-nine cases in literature were reviewed. Among them, 14 cases of spinal epidural hematoma were due to ruptured angioma which were verified histologically. Others were unknown causes. Age distribution was discussed. It was suggested that the younger patients in the group of unknown causes might have angiomas. It was emphasized that it should not be overlooked even the insignificant transient symptoms and should schedule the extensive radiological examination in such cases.

Combined intrathecal metrizamide and arterial injection of contrast medium during dynamic computed tomography scanning was used to define the morphology and topographic aspects of a thoracic arteriovenous malformation. The information obtained from this new technique was decisive in establishing the operability of the lesion.

Metrizamide (Amipaque) is a new water-soluble contrast medium for myelography. It differs from the conventional contrast media in that, because of its lower toxicity, it can be used also for cervical and thoracic myelography. The method of examination in myelography with water-soluble contrast media differs in some respects from that in myelography with oil-soluble contrast media. For the thoracic region, tomography is highly recommendable. After a description of the method of examination used, some examples of the abnormalities found are presented.

A very simple procedure is described which leads to adequate visualization of the structures in the craniocervical area that are otherwise often very insufficiently investigated during myelography routinely performed with metrizamide.
