Remission of obsessive-compulsive symptoms following temporoparietal haemorrhage: a case report

Many etiological factors have been implicated in the pathophysiology of obsessive-compulsive disorder (OCD). The non-invasive neuroimaging studies regarding the pathophysiology of OCD indicate the abnormalities in distinct brain regions. Cortico-striato-thalamo-cortical (CSTC) tracts are proposed to be involved in OCD symptomatology. Reports of OCD cases after a brain injury including cerebrovascular accident (CVA) also support the involvement of CSTC pathways in OCD. Moreover, a few cases of OCD whose OC symptoms displayed an improvement after CVA in the brain regions related CSTC tracts. These reports will guide the surgical interventions in OCD. Here, we present a case of OCD whose symptoms resolved within a few days after a haemorrhage in the left temporo-parieto-occipital lobes. In this case, we supposed that the compression of the subcortical striatal tissues which is known to be involved in the OCD pathophysiology might be associated with the resolution of OCD symptoms.
