Sexual Abuse and Suicide Attempt in Bipolar Type I Patients

over the previous 2 months. She had no history of alcohol or other drug abuse, and no prior psychiatric history. Blood tests, serologies, drug screening, and electroencephalography (EEG) showed no abnormalities. The patient had been on citalopram 20 mg/day for 1 month as prescribed by her geriatrician. We decided to switch her medication to quetiapine 50 mg/day, and requested a head computed tomography (CT) scan and advice from the neurology service. After 2 weeks, the patient was more communicative and said that her husband had been filming her at home. Head CT showed no abnormalities, and she was discharged from the neurology service. However, we insisted that a magnetic resonance imaging (MRI) scan of the brain should be performed and increased the dose of quetiapine to 100 mg/day. At 1-month follow-up, the patient was asymptomatic and asked: ‘‘How could I believe that my husband wanted to harm me? ’’ MRI showed a small meningioma in the left frontal high convexity (Figure 1A) and she was referred for neurosurgical evaluation, but the neurosurgeon recommended watchful waiting. The patient returned after 1 year, still on regular quetiapine therapy (100 mg/day). Although well, she complained of headaches and memory lapses. There were no signs or symptoms of intracranial hypertension. Blood tests, serologies, and EEG remained normal. Nevertheless, we requested another MRI scan, which showed enlargement of the frontal meningioma and emergence of a new tumor in the cribriform plate of the ethmoid (Figure 1B). Two weeks later, the patient came to evaluation in a very agitated state, asking why we had ‘‘posted what she had told us on Facebook. ’’ After a 30-day course of olanzapine 5 mg/day, the patient improved substantially. Olanzapine was well tolerated and the patient did not experience adverse effects. When last seen in August 2014, she was well and remained on olanzapine 5 mg/day. Meningiomas are benign neoplasms of the central nervous system, highly prevalent among elderly women. Benign cerebral tumors such as these may not cause any symptoms other than psychiatric manifestations until they are quite large. Analyses of correlation between peritumoral edema and coexistence of psychiatric symptoms have indicated that the underlying pathophysiological mechanism is likely related to disruptions in intracerebral pathways rather than with a mass effect of meningioma on intracranial pressure. Indeed, headache, papilledema, and focal neurological signs often arise only when the meningioma has reached an advanced stage. Often, the correct diagnosis is established only after intracranial hypertension has caused irreversible cerebral damage. Meningiomas can cause delusions, especially when located in the cerebral convexities. Based on the case reported herein, a low dose of olanzapine seems to be safe and effective for the treatment of such clinical presentations. When an older adult with no history of mental illness develops psychiatric symptoms, other medical conditions should be considered in the differential diagnosis. Severe diseases may be overlooked if this recommendation is disregarded.
