A, Anterior-posterior DSM demonstrates a CSF-venous fistula (BMI = 46.9 kg/m2, weight 149 kg, height = 178 cm). B, Lateral DSM demonstrates a CSF-venous fistula (BMI = 40.6 kg/m2, weight = 94.5 kg, height = 152 cm). C, Anterior-posterior DSM demonstrates a CSF-venous fistula (BMI = 40.2 kg/m2, weight = 113 kg, height = 167 cm). D, Anterior-posterior DSM demonstrates a CSF-venous fistula (BMI = 53.7 kg/m2, weight = 151 kg, height = 167 cm). E, Anterior-posterior DSM demonstrates a CSF-venous fistula (BMI = 41 kg/m2, weight = 137 kg, height = 183 cm). F, Anterior-posterior DSM demonstrates a CSF-venous fistula (BMI = 45.4 kg/m2, weight = 161 kg, height = 188 cm). In 2 other patients (BMI = 56.3 kg/m2, weight = 149 kg, height = 163 cm and BMI = 41.8 kg/m2, weight = 140 kg, height = 182 cm, respectively), DSM failed to demonstrate a CSF-venous fistula. Arrows indicates CSF-venous fistulas.
