The patient underwent brain CT scan again in our centre, which revealed hydropneumocephalus in the frontal parenchyma with midline shift and compression effect on the anterior horn of the lateral ventricles in the right frontal lobe (figure 1).
Magnetic resonance imaging (MRI) with contrast (Axial, coronal and sagittal views) revealed no rim enhancement around the lesion, which ruled out brain abscess and confirmed tension hydropneumocephalus diagnosis
