A 66-year-old woman with urinary and fecal incontinence, headache, and worsening of pre-existing left hemiparesis consulted preoperatively for progressive behavioral changes ongoing for 10 months. While she was a person displaying contextually appropriate behaviors and participating in daily activities; she gradually became detached, devoid of self-generated behavior, also was irritable and behaved inappropriately. She was even indifferent to her urinary and fecal incontinence. On occasion, she exhibited disinhibition and impulsivity,3 characterized by uncontrollable swearing and throwing of objects. Furthermore, seemingly unable to suppress the urge, she consumed food whenever presented, despite the fact that she had just eaten a full meal (namely, utilization behavior).3 Motor examination revealed left-sided weakness, more prominent in the arm (MRC: 2/5). Brain imaging demonstrated a midline subfrontal meningioma of 30×10×25-mm size, compressing predominantly the right lobe. The day after consultation, the mass was excised totally, and pathology demonstrated a transitional meningioma. Three months after surgery, the dysexecutive syndrome3 fully recovered; however, left hemiparesis persisted. Interestingly, at age 38, she had undergone a decompression surgery for a subfrontal meningioma, as well. Reportedly, she displayed ongoing antisocial behavior3 characterized by emotional disengagement, reduced goal-directed behavior, and unpredictable aggressive outbursts for 1 year. Aforementioned dysexecutive symptoms3 preceded a left hemiparesis, which occurred 2 months before total excision. In the follow-up, although dysexecutive syndrome3 had recovered entirely, left hemiparesis persisted, with incomplete recovery, until further deterioration due to recurrence.
