A Case of Suprasellar, Intrasellar, and Infrasellar Meningioma Presenting as a Visual Field Defect in an Obese Female

Abstract

Bitemporal hemianopia is the most common visual field defect encountered in suprasellar meningiomas compressing the optic chiasma and its vascular supply. It is hard to distinguish between meningioma and tumors that arise from suprasellar, intrasellar, and infrasellar extensions. Clinical findings, hormonal levels, and radiological findings could help in labeling it as meningioma. A 53-year-old obese woman with a history of blurred vision more in the right eye, loss of smell, and a headache was diagnosed with meningioma having suprasellar, intrasellar, and infrasellar extension on neuroimaging. She developed bitemporal hemianopia, which gradually worsened over the course of six months with concomitant headaches and dizziness that was treated with analgesics leading to a delayed diagnosis. As she was symptomatic, it was decided to resect her tumor. The patient underwent an endoscopic transsphenoidal approach for tumor resection. Successful excision of the tumor was accomplished. Postoperatively on further evaluation, the patient's anosmia and the visual deficit were resolved. This instance shows that meningioma located in the sella can cause symptoms like anosmia and visual field loss, which should not be neglected. It also underlines the significance of visual field evaluation on a regular basis as this might predict radiological and symptomatic progression.

Trigeminal Neuralgia Triggering Recurrent Attacks of Migraine in a Chronic Migraineur: A Hidden Etiology Between the Lines

“…Conversely, migraine episodes last from four to 72 hours and are usually one-sided, pulsatile headaches along with vomiting, photophobia, and phonophobia. Notably, a majority of migraines occur without aura, although a subset of patients experience a prodromal sensory or visual disturbance [ 11 ]. The pathophysiology involves cerebral vascular changes and the release of vasoactive neuropeptides, influenced by a variety of environmental and physiological factors [ 12 ].…”

World Health Organization (WHO) Grade 1 Astrocytoma in a Female From Rural India: A Case Report

“…When located in the hypothalamus, the tumors may cause endocrine disturbances and might lead to diabetes insipidus, precocious puberty, or electrolyte imbalance. When present in the optic pathways, the tumor may cause loss of visual acuity or field abnormalities [ 4 ]. Optic nerve tumors are reported to be linked to radiotherapy, while brainstem tumors are related to chemotherapy [ 5 ].…”
