Occipital lobe meningioma in a patient with multiple chemical sensitivities
1University of Utah, Rocky Mountain Center for Occupational and Environmental Health, Department of Family and Preventive Medicine, Salt Lake City, UT 84112-5120, USA.
Background:
The concurrent diagnosis of meningioma with increased intracranial pressure has not been reported previously in a patient who meets diagnostic criteria for multiple chemical sensitivities (MCS).
Methods:
A patient who had been evaluated in an occupational medicine practice, and by several other physicians for sensitivity to chemical odors was found to have papilledema and a visual field deficit. The patient met the clinical criteria set forth by Cullen in 1987 for MCS. A magnetic resonance imaging (MRI) scan was performed.
Results:
The MRI revealed a large occipital lobe meningioma, which was surgically resected. Removal of the meningioma had little effect on the patient's symptoms. She has been unable to return to her job as a custodian.
Discussion:
The etiology of MCS has been disputed and is currently unresolved. Those who evaluate patients with MCS are reminded that meningiomas and other intracranial mass lesions can affect olfaction, and that patients with MCS can have treatable intracranial abnormalities.
Insights
A rare case report details a patient with multiple chemical sensitivities (MCS) diagnosed with an intracranial meningioma. Surgical removal of the tumor did not resolve the patient's MCS symptoms, highlighting the need for further investigation.
Area of Science:
- Neurology
- Occupational Medicine
- Oncology
Background:
- Multiple Chemical Sensitivities (MCS) diagnosis remains controversial.
- Concurrent diagnosis of meningioma and MCS with increased intracranial pressure is unprecedented.
- Patient presented with symptoms evaluated by multiple physicians for chemical sensitivities.
Observation:
- The patient exhibited papilledema and visual field deficits.
- Magnetic Resonance Imaging (MRI) revealed a large occipital lobe meningioma.
- The patient met Cullen's 1987 diagnostic criteria for MCS.
Findings:
- Surgical resection of the meningioma was performed.
- Tumor removal had minimal impact on the patient's reported MCS symptoms.
- The patient was unable to return to her custodial work.
Implications:
- Intracranial mass lesions, such as meningiomas, can impact olfactory function.
- Clinicians evaluating MCS patients should consider and rule out treatable intracranial abnormalities.
- This case underscores the complexity of MCS and potential neurological underpinnings.
