['Histrionic personality disorder with regression and conversion': a meningioma]

Area of Science:

• Neuroscience
• Neurology
• Psychiatry

Background:

• Meningiomas are tumors arising from the meninges.
• They can present with diverse neurological and psychiatric symptoms.

Observation:

• A 47-year-old woman initially diagnosed with histrionic personality disorder was found to have a frontal meningioma.
• Her psychiatric symptoms preceded overt neurological signs.

Findings:

• Meningiomas can manifest primarily with psychiatric disturbances, complicating diagnosis.
• Delayed diagnosis is common due to misleading symptoms and established psychiatric diagnoses.

Implications:

• This case highlights the importance of considering organic brain lesions in psychiatric patients.
• Characteristic signs of meningioma and indications for brain imaging in psychiatric patients warrant discussion.
