Phlebectasia of left Internal Jugular vein

The left internal jugular vein appears moderately dilatated as seen in these B mode and color Doppler images of the neck. This is a not so uncommon finding during routine ultrasound imaging of the neck usually for thyroid related conditions. At 16 mm. maximal diameter the left IJV appears moderately distended. The patients in such cases are usually asymptomatic.

Hidden VUJ calculus

This male patient reveals the difficulties the radiologist often faces when trying to discover the location of a ureteric calculus. At first the patient complained of pain in the left iliac region suggested a case of mid ureteric calculus. However, despite the hydronephrosis of the left kidney and a mild hydroureter on the left side, it was very difficult to locate a calculus which was actually located at its distal end, namely the left vesico-ureteric junction. a lot of factors were unfavourable to locate this calculus at the left vesicoureteric junction. First, the patient had a rather hyper distended bladder. Also, the left hydroureter was mild. Besides, the patient also had significant bowel gas. finally, the calculus itself was rather small at 6.5 mm.
