The swelling markedly increases in size and was fusiform in shape on performing valsalva maneuver [Figure 1].
Contrast-enhanced computed tomography (CECT) neck showed mildly dilated right Internal jugular vein (IJV) at rest, markedly increasing in size with valsalva maneuver. The focal fusiform swelling on valsalva measured 24 and 35 mm as max. Antero-posterior and transverse diameter respectively (a). The swelling extended from C4 vertebral body level to clavicle for cranio-caudal length of 7 cm (b). However, on performing valsalva maneuver, the entire right IJV (c), ipsilateral sigmoid and transverse sinus (d) were noted to be very prominent, compared to the normal left side. Screening CECT of brain revealed no additional abnormality

AP and transverse diameter respectively [Figure 2a]. The swelling extended from C4 vertebral body level to clavicle for cranio-caudal length of 7 cm [Figure 2b]. However, on performing valsalva maneuver, the entire right IJV [Figure 2c], ipsilateral sigmoid and transverse sinus [Figure 2d] were noted to be very prominent, compared to the normal left side.
