Patient with a brain abscess in the left middle frontal gyrus. (a) Location of the lesion as measured from the middle of the orbital rim. (b) Location of the lesion over the 3D model. (c) Simulation of the craniotomy window, skin incision, and superficial brain anatomy. (d) Minimal hair removal and a linear skin incision centered over the estimated position of the lesion. (e and f) The whole brain after skin-and-bone removal. The abscess is located below the Y-shaped dural venous channels. (g) Intraoperative correlation presenting the Y-shaped dural venous channels in the center of the craniotomy. The abscess was removed with full recovery of the patient
