The patients described in this article presented the “Modified Dandy criteria” (<a class="elsevierStyleCrossRef" href="#tbl0005">Table 1</a>) on the MRI.

Nonetheless, the patient did not show pre-surgical symptoms or signs of high ICP (neither visual alterations, nor ventricular dilatation or indirect sings in the MRI). The fact that the patient did not present any symptoms or signs of high ICP after the surgery supports the suspicion that the patient did not suffer from high ICP.

Therefore, it is recommended adequate dural and bony closure for all intracranial surgery, particularly in the posterior fossa surgeries and in high-risk patients. Since the late 1960s, authors have also demonstrated a correlation between obesity and increases in intracranial pressure. Increased intra-abdominal pressure creates a cascade of events that decreases venous return from the brain, leading to a non pathological increase of the intracranial pressure.
