"Haemorrhage is demonstrated as a region of hyperdensity in the basal ganglia. If there is no intraventricular extension, the haemorrhage volume may be estimated by ABC/2 and related formulas, which may have neurosurgical and prognostic implications."

"The presentation will vary widely depending on the patient's medical history and the size of the haemorrhage. There is a strong association between basal ganglia haemorrhage and lacunar syndromes, for example, haematomas involving the posterior limb of the internal capsule will lead to contralateral motor deficits 7,8. Patients can present with an ipsilateral deviation of the eyes due to descending capsular pathways from the frontal eye field."
"There are many predictors of haematoma expansion potentially evident on CT, which are discussed in depth in the main intracerebral haemorrhage article."
