Abstract

Neuropsychiatric sequelae are the predominant long-term disability after traumatic brain injury (TBI). This study reports a case of late-onset social anxiety disorder (SAD) following TBI. A patient that was spontaneous and extroverted up to 18-years-old started to exhibit significant social anxiety symptoms. These symptoms became progressively worse and he sought treatment at age 21. He had a previous history of traumatic brain injury (TBI) at age 17. Neuroimaging investigations (CT, SPECT and MRI) showed a bony protuberance on the left frontal bone, with mass effect on the left frontal lobe. He had no neurological signs or symptoms. The patient underwent neurosurgery with gross total resection of the lesion and the pathological examination was compatible with intradiploic haematoma. Psychiatric symptoms may be the only findings in the initial manifestation of slowly growing extra-axial space-occupying lesions that compress the frontal lobe from the outside. Focal neurological symptoms may occur only when the lesion becomes large. This case report underscores the need for careful exclusion of general medical conditions and TBI history in cases of late-onset SAD and may also contribute to the elucidation of the neurobiology of t...Continue Reading
