Different approaches to the anterior third ventricle have been described; among them are the trans-cortical, the subfrontal
, and the interhemispheric transcallosal.
The mean procedure length was 124.5 +-17.9 minutes.In 26 (43.33%) patients bicoronal craniotomy was performed where wide exposure was needed and in 34 (56.67%) unilateral subfrontal
approach was adopted.

PET/CT imaging was unremarkable except for mild subfrontal
increase uptake (possibly leptomeningeal involvement).

It shows that there is arrested general growth but increased breadth in the subfrontal

lamina terminalis approach may be used [22,24].
Fedor Krause (1857-1937) proposed a subfrontal

Subsequent magnetic resonance imaging (MRI) identified an enhancing mass involving the left subfrontal
area of the brain with contiguous involvement of the left ethmoid air cell and intracranial extension (figure 1).
