Failure of computerized axial tomography to demonstrate a chronic subdural hematoma. 1976

A B Dublin, and J M Rennick, and S Sivalingam

A chronic subdural hematoma may present in a computerized axial tomography (CAT) scan with the same density as normal brain tissue. The presence of a lesion may be suggested only by its mass effect. The lack of contrast enhancement or edema may help to differentiate a chronic subdural hematoma for a neoplasm or a cerebrovascular accident.

D002908	Chronic Disease	Diseases which have one or more of the following characteristics: they are permanent, leave residual disability, are caused by nonreversible pathological alteration, require special training of the patient for rehabilitation, or may be expected to require a long period of supervision, observation, or care (Dictionary of Health Services Management, 2d ed).

D006408	Hematoma, Subdural	Accumulation of blood in the SUBDURAL SPACE between the DURA MATER and the arachnoidal layer of the MENINGES. This condition primarily occurs over the surface of a CEREBRAL HEMISPHERE, but may develop in the spinal canal (HEMATOMA, SUBDURAL, SPINAL). Subdural hematoma can be classified as the acute or the chronic form, with immediate or delayed symptom onset, respectively. Symptoms may include loss of consciousness, severe HEADACHE, and deteriorating mental status.
