Role of Diffusion MRI Tractography in Endoscopic Endonasal Skull Base Surgery
Published on: July 5, 2021
Abstract:
Investigations were carried out on 27 cases of cranial eosinophilic granuloma: 16 males (59%) and 11 females (41%). The mean age was 25 years, the extremes being 2 years and 65 years. The location in 21 cases (80%) was exclusively in the calvarium (9 frontal, 8 parietal, three occipital and 1 temporal), orbital in two cases, fronto-orbital one case, base of the skull in the left parasellar region one case, left frontal subdural with chronic subdural haematoma one case and one case left occipital and petrosal bone. All the cases were diagnosed histologically. In 18 cases the tumour was removed at operation. Recurrences occurred in four of these cases (15%), three of whom died (11-5%). Four of the patients received steroid therapy and four steroid therapy combined with X-ray therapy. The evolution was favourable in all these cases.

Cranial Bones: Lateral View
The temporal bone forms the lower lateral side of the skull. The temporal bone is subdivided into several regions. The flattened upper portion is the squamous portion of the temporal bone. Below this area and projecting anteriorly is the zygomatic process of the temporal bone, which forms the posterior portion of the zygomatic arch. Posteriorly is the mastoid portion of the temporal bone. Projecting...
