“…However this is an invasive technique and has an associated morbidity. As a screening tool, myelography 11 , contrast enhanced dynamic CT scan 12,13 and magnetic resonance imaging (MRI) scan 14,15 have each been successfully utilized to identify these lesions. Our patient underwent a contrast enhanced dynamic CT scan on the advice of our radiology department.…”

A 27-year-old female with Klippel-Trenaunay Syndrome presented for reconstructive surgery of the deep venous system of the right leg. Contrast enhanced dynamic computed tomography was performed to exclude the presence of arteriovenous malformation of the lumbosacral spine. A combined spinal-epidural technique supplemented with light general anaesthesia was performed. The patient's condition was stable throughout the three hours of surgery and postoperative analgesia was maintained successfully for three days.

“…Gaiser et al 7 made use of a MRI scan. Although it is reported that MRI scan may define the anatomy of spinal AVM more accurately than a contrast enhanced dynamic CT scan, both may be used as screening tools [12][13][14][15] .…”

“…Myelography and standard MRI have the sensitivity to establish the diagnosis of SAVM as a possibility. [7][8][9] Multidetector CT-angiography and MR angiography can provide excellent anatomic definition for some SAVMs but not in all the cases and certainly the size of feeding vessels to these malformations is sometimes beyond the resolution of these modalities. 1,2,4,10 Three-dimensional rotational spinal angiography can be another safe and effective method for evaluation of SAVMs.…”

Objectives: Presenting 4 cases of spinal arteriovenous malformations (SAVMs) with typical spinal magnetic resonance imaging (MRI) and myelogram, but negative complete selective spinal angiography (SAG) and a ''hard to explain'' postoperative course.Materials and Methods: All were male patients of 40 to 50 year of age presenting with progressive paraparesis and sphincter disturbance. MRI, spinal myelography, multislice spinal computed tomographic angiography, and digital subtraction selective SAG was performed. The surgical treatment is described and the videos of 2 cases are demonstrated. Even though all the patients had slow and acceptable improvement in the short postoperative course but in longer follow-up, the clinical improvement continued slowly in 1 case, plateaued in 1 case, and paraplegia recurred in 2 cases.Results: Low intensity intramedullary ellipsoid shadow in T1-weighted spin echo MRI, turning to a homogenous bright high signal intensity lesion in T2-weighted sequence with flow void serpentine images located in the dorsal aspect of the spinal cord in multiple levels were the typical findings. Ill-defined filling defects visualized in myelography was present in all 4 cases. Digital subtracted selective SAG did not show any abnormal vessels in any of the cases.Conclusions: (a) There are still unusual variants of SAVMs that neurosurgeons should recognize, (b) there should be an acceptable explanation for the lesions being angiographically invisible, and (c) the natural course and outcome of the angiographically occult SAVM is not known and unexpected events can be anticipated in long-term follow-up of similar cases.
