Patient Data

Age: 50 years
Gender: Male

Aperistaltic tubular blind-ending structure on RLQ, non-compressible, consistent with appendix. Dilated appendix 9 mm in diameter, with signs of slight hyperemia (Power Doppler study).

Small hypoechoic area surrounding the tip of the appendix, indicating fluid. 

Tenderness on ultrasound probe palpation, more prominent when corresponded with the dilated appendix. 

Additional findings are multiple large cysts on both kidneys and small ones on the liver parenchyma, as of autosomal dominant polycystic disease

Case Discussion

The findings were consistent with acute appendicitis

The patient went on an-open-surgery appendectomy directly afterwards, which confirmed the diagnosis of acute appendicitis.
