Chickenpox and an Abdominal Mass

A 1 10/12-year-old girl was brought to our ER with a bellyache and one-time vomiting at home. The mother also mentioned a swollen mass in the right upper quadrant of the abdomen. Fever up to 39°C and nausea. The mother noticed the painful mass in the right upper quadrant of the abdomen by accident, but it did not seem alarming to her, because of the chickenpox the girl had a week prior to presentation.

Decreased general condition, tachycardia of 164 bpm, SpO2 98%, T 37.8°C, fluctuating swollen mass in the upper right quadrant of the abdomen, 3cm in diameter, slightly red and warm, painful to the touch. Remaining examination was normal.
