A 69-year-old right-handed man who exhibited unilateral spatial neglect in
association with a chronic subdural haematoma, presented with mild left arm
and leg weakness first noted 4 weeks prior to admission. Neurologic examin
ation on admission revealed a mild left hemiparesis, including the face. Ne
uropsychologic examination revealed left unilateral spatial neglect, but no
language disturbance. Minimal support was necessary to maintain activities
of daily living. Computed tomography revealed a large right temporoparieta
l, extraaxial hypodense fluid collection containing scattered hypodense foc
i. The haematoma was evacuated via a right parietal burr hole. Following su
rgery, the patient dramatically improved neurologically and neuropsychologi
cally, as well as in independent performance of daily activities. It is sug
gested that the improvement in ADL provides a behavioural correlate of impr
ovement in the latter, represented a behavioural correlate of improved cere
bral function, and that either direct compression by the chronic subdural h
aematoma or an interhemispheric pressure difference had caused unilateral s
patial neglect. Such neglect is an unusual consequence of chronic subdural
haematoma.
