A Wilm’s tumour was suspected. Check the images below, leave your thoughts in the comments section and come back for the answer on Friday.

      with this presentation I would suspect round pneumonia- the opacification is outlined by the transverse fissure pleura.
      Renal abscesses and infections are pretty common and could be complicated with urosepsis and lung lesions or it could be the other way around.

      …polmonite rotonda….

      Paediatric round pneumonia.
      Limited by the lobe. indistinct margin argues against pleural tumour. Wilms tumour seldom mets to lung.

    4. gus says:

      Round pneumonia

    5. magda says:

      round pneumonia in the middle lobe of right lung (bordered by the minor fissure on the bottom side)

    7. vijay says:

      rounded soft tissue mass with ill defined borders in right upper lobe ,.abutting the horizontal fissure
      1.could be round pneumonia..abdominal mass could be infected kidney mass or liver abscess
      2. could be wilms tumour with pulmonary cannonball metastases

      considering the mild fever i would go more in favour of films as septicaemia will cause high grade fever and more debilitated condition of child

    8. Jose Caceres says:

      At this stage of the game I cannot convince anybody that the child doesn’t have a round pneumonia!
      Good for you!
