“…According to our review about the coexistence of multiple types of spinal vascular lesions, the collected data in this review included demographic data (i.e., patient gender and age), symptoms and signs, type with location of each fistula, synchronous or metachronous occurrence of these fistulas, the presence of sharing the same venous drainage, treatment, and neurological outcome of the patients [ Table 2 ]. [ 2 , 4 - 7 , 9 , 10 , 12 , 13 , 15 , 16 , 19 , 20 ] Our search found 18 cases including our case with 36 spinal vascular lesions. There were 13 men (72.2%) and 5 women (27.8%).…”

“…In addition, Rosi et al . [ 19 ] reported five cases of concomitant conus AVM or AVF and sacral DAVF and assumed that the concurrent lesions are the pathophysiological linked. Most dural fistulas were found in the area in which the venous drainage of the conus lesions ended.…”

Background: Cauda equina arteriovenous fistulas (AVFs) fed by the proximal radicular artery are exceedingly rare. Spinal dural arteriovenous fistulas (DAVFs) in the sacral region are rare and usually misdiagnosed. We report a case of a cauda equina AVF with concomitant sacral DAVF. We also review the coexistence of multiple types of spinal vascular malformations in a single patient. Case Description: A 54-year-old man presented with progressive weakness of the lower extremities for 1 month. Magnetic resonance imaging (MRI) of the lumbosacral and thoracic spine showed spinal cord congestion, extending from the conus medullaris to the level of T7, and abnormal tortuous and dilated flow void, running from the level of L5 to T12 along anterior surface of the spinal cord. Spinal angiography demonstrated the fistula at the level of L2 below the conus medullaris. Based on intraoperative findings, the cauda equina AVF supplied by the proximal radicular artery with cranial drainage through the enlarged radicular vein was confirmed and successfully obliterated. Another enlarged arterialized radicular vein running parallel to another cauda equina nerve root is observed with unknown origin. After the operation, the patient showed mild improvement of his symptoms. Follow-up MRI and contrast-enhanced MR angiography revealed an another sacral DAVF vascularized by the lateral sacral artery. Conclusion: The coexistence of different spinal vascular malformations in a same patient is extremely rare. Most authors of several studies hypothesized that venous hypertension and thrombosis due to the presence or treatment of the first spinal vascular lesion may produce a second DAVF.

“…The co-existence of different types of spinal cord arteriovenous shunts is very rare. 60 Concomitant existence of spinal lipoma and acquired spinal AVF is also very rare. The lipoma releases angiogenic factors that are involved in the development of the spinal AVF.…”

Tracheoesophageal fistula and esophageal atresia are rare congenital abnormalities which represent two components of VACTERL association of anomalies. They are frequently associated with laryngeal cleft. Congenital umbilical fistulas result from failure of obliteration of the fetal vitellointestinal duct or urachus. Vitellointestinal duct abnormalities are rare and they include Meckel's diverticulum, vitelline cyst and vitellointestinal fistula. Urachal anomalies are very rare, and they include diverticula, cysts, sinuses and fistulas. Ultrasonography and fistulography are helpful investigations for the diagnosis of urachal fistulas; the fistula is surgically excised together with the adjoining apex of the urinary bladder. Congenital prepubic sinuses and urethroperineal fistulas are other rare anomalies. Congenital coronary artery fistulas may be also discovered between the coronary arteries and the four cardiac chambers or the great vessels of the heart. Coronary arteriovenous fistulas and absent ductus venosus with abnormal venous circulation could occur as rare congenital anomalies. Other rare congenital arteriovenous fistulas could exist in the thorax, abdomen, pelvis, and cranial and spinal meninges.

“…Through beautiful case illustrations, Rosi and colleagues describe the rare association between conus medullaris arteriovenous shunts and lumbosacral dural arteriovenous fistulas (DAVFs) 10. In the event of a thoracolumbar AVM with caudal venous drainage, the authors recommend further investigation to rule out an associated lumbosacral DAVF.…”
