Suprasellar meningioma and blindness: a unique experience in Saudi Arabia.

BACKGROUND

The natural history of intracranial meningioma is no different in the Arabian peninsula than in other countries. The extent of the total loss of vision in one or both eyes, however, is unique to this area.

METHODS

A retrospective study was conducted at King Faisal Specialist Hospital and Research Centre, a tertiary care institution in Saudi Arabia, on all cases of intracranial meningioma seen over a period of 9 years. The following data were collated: clinical presentation, site and size of tumor, radiologic features, surgical methods, and preoperative and postoperative visual status.

RESULTS

Seventy of 232 cases (30.1%) of intracranial meningioma presented in the suprasellar area; the majority of these were more than 5 cm in diameter. Because of the large size it was not always possible to identify the exact point of origin or to achieve complete tumor removal. Deteriorating vision was the cardinal presenting feature and the incidence of blindness in one or both eyes at presentation was high (42.2%); 12.8% were totally blind on admission. None of these patients showed improvement after surgery (complete or subtotal removal of tumor).

CONCLUSION

Lack of understanding of the symptoms and cultural influences are direct contributing factors to this complication of a benign intracranial lesion. This represents a serious public health concern in the Arabian peninsula.
