| internal hydrocephalus | Hydrocephalus in which the accumulation of fluid is confined to the ventricles; also occurs as an autosomal recessive condition in the Hereford and Holstein breeds of cattle. (05 Mar 2000) |
| obstructive hydrocephalus | Hydrocephalus secondary to a block in cerebrospinal fluid flow in the ventricular system or between the ventricular system and spinal canal. Synonym: noncommunicating hydrocephalus. (05 Mar 2000) |
| occult hydrocephalus | <neurology> A brain disorder caused by blockage of the flow of cerebrospinal fluid (CSF), with enlargement of the ventricles of the brain (keep the pressure normal) and compression of brain tissue. Brain atrophy is the result. In this condition the CSF is produced normally but not reabsorbed. Symptom onset is gradual. A key feature is dementia. Treatment is surgical (VP shunt). (13 Nov 1997) |

| thrombotic hydrocephalus | Increase in cerebrospinal fluid and of intracranial pressure following thrombosis of the cerebral veins or sinuses; caused by septic infection, dehydration, tuberculosis, typhoid, leukaemia, and other conditions. (05 Mar 2000) |
| toxic hydrocephalus | Thrombotic hydrocephalus associated with some general infection or toxic state. (05 Mar 2000) |
| external hydrocephalus | Accumulation of fluid in the subarachnoid spaces of the brain, accumulation of fluid in the subdural space owing to a persistent communication between the subarachnoid and subdural spaces. (05 Mar 2000) |

| Abadie's sign of tabes dorsalis | Insensibility to pressure over the tendo achillis. (05 Mar 2000) |
| Abrahams' sign | <clinical sign> An obsolete sign: Rales and other adventitious sounds, changes in the respiratory murmurs, and increase in the whispered sound can be heard on auscultation over the acromial end of the clavicle some time before they become audible at the apex; heard primarily in pulmonary tuberculosis affecting the apical portion of the lung, a dull-flat note, i.e., one between the normal dullness at the right apex and absolute flatness, heard on percussion in that region, indicating progress from incipient to advanced tuberculosis. (05 Mar 2000) |
| accessory sign | <clinical sign> A finding frequently but not consistently present in a disease. Synonym: assident sign. (05 Mar 2000) |
| Allis' sign | <clinical sign> In fracture of the neck of the femur, the trochanter rides up, relaxing the fascia lata, so that the finger can be sunk deeply between the great trochanter and the iliac crest. (05 Mar 2000) |
| Amoss' sign | <clinical sign> In painful flexion of the spine, it is necessary to support a sitting position by extending the arms behind the torso with the weight placed on the hands. (05 Mar 2000) |
