A child of 4 years old with suspected appendicitis came to emergency department of city children hospital and is sent for an abdomen ultrasound scan.
At ultrasound, the appendix was not visualized, but in the lower right quadrant (RLQ) of the abdomen the tubular convoluted structure was visualized, which I initially interpreted as mesadenitis, on the CFM(DPD) the picture changed, the structure uniformly colored, in the spectral Doppler mode the monophasic blood flow (by venous type) upto 16 cm / sec - presumably phlebectasia/ congenital anomalous blood vessel - external link
