Abstract

Purpose: To highlight the clinical and neuro-imaging patterns of Meningiomas of
visual pathway.
Materials and Methods: It was a descriptive retrospective study conducted
during 2007 to 2013. 94 patients with intra cranial Meningiomas affecting the
visual pathway were selected for study. Clinical data included history, ocular and
systemic examinations and neuro-imaging reports. Special attention was given
to the neurological data, which was the only source available to us for
diagnosing Meningiomas. Histological confirmation of Meningioma was available
in 9.6% cases (n = 9).
Results: Ninety – four patients, 51 females and 43 males (female: male ratio,
1.19:1) were included in the study. Mean age was 48.23 years. The commonest
type of Meningioma affecting visual pathway was Meningioma of inner table of
occipital bone causing mass effects on the occipital lobe (30.85%, n = 29). Other
Meningiomas were Parasellar (21.3%, n = 20) and supra sellar Meningiomas
(18.1%, n = 17) pressing upon optic chiasma. Tumor size ranged from 0.7 cm to
8.5 cm in smallest and largest dimensions respectively. Only one patient in our
series had neurofibromatosis type 1 and one patient had neurofibromatosis type
2.
Conclusion: Neuro-imaging including conventional radiology plays a pivotal role
in non-interventional diagnosis of intracranial Meningiomas. Owing to the benign
nature of Meningioma, it should be differentiated from other aggressive tumors
which need to be diagnosed and treated at the earliest.
Key words: Parasellar Meningiomas, Supra sellar Meningiomas, visual
pathway, Dural tail sign, Neuro-imaging
