REASON FOR VISIT: , The patient is a 74-year-old woman who presents for neurological consultation referred by Dr. X.  She is accompanied to the appointment by her husband and together they give her history.,HISTORY OF PRESENT ILLNESS: , The patient is a lovely 74-year-old woman who presents with possible adult hydrocephalus.  Danish is her native language, but she has been in the United States for many many years and speaks fluent English, as does her husband.,With respect to her walking and balance, she states "I think I walk funny."  Her husband has noticed over the last six months or so that she has broadened her base and become more stooped in her pasture.

She has very mild kyphosis, but no scoliosis.,SKIN:  There are no neurocutaneous stigmata.,CARDIOVASCULAR EXAM:  Regular rate and rhythm.  No carotid bruits.  No edema.  No murmur.  Peripheral pulses are good.  Lungs are clear.,MENTAL STATUS:  Assessed for recent and remote memory, attention span, concentration, and fund of knowledge.

There was no drift or tremor.,SENSORY EXAM:  Intact for pinprick and proprioception.,COORDINATION:  Normal for finger-to-nose.,REFLEXES:  Are 2+ throughout.,GAIT:  Assessed using the Tinetti assessment tool.  She was fairly quick, but had some unsteadiness and a widened base.  She did not need an assistive device.  I gave her a score of 13/16 for balance and 9/12 for gait for a total score of 22/28.,REVIEW OF X-RAYS: , MRI was reviewed from June 26, 2008.  It shows mild ventriculomegaly with a trace expansion into the temporal horns.  The frontal horn span at the level of foramen of Munro is 3.8 cm with a flat 3rd ventricular contour and a 3rd ventricular span of 11 mm.  The sylvian aqueduct is patent.  There is no pulsation artifact.  Her corpus callosum is bowed and effaced.  She has a couple of small T2 signal abnormalities, but no significant periventricular signal change.,ASSESSMENT:  ,The patient is a 74-year-old woman who presents with mild progressive gait impairment and possible slowing of her cognition in the setting of ventriculomegaly suggesting possible adult hydrocephalus.,PROBLEMS/DIAGNOSES:,1.  Possible adult hydrocephalus (331.5).,2.  Mild gait impairment (781.2).,3.  Mild cognitive slowing (290.0).,PLAN: , I had a long discussion with the patient her husband.,I think it is possible that the patient is developing symptomatic adult hydrocephalus.  At this point, her symptoms are fairly mild.  I explained to them the two methods of testing with CSF drainage.  It is possible that a large volume lumbar puncture would reveal whether she is likely to respond to shunt and I described that test.  About 30% of my patients with walking impairment in a setting of possible adult hydrocephalus can be diagnosed with a large volume lumbar puncture.  Alternatively, I could bring her into the hospital for four days of CSF drainage to determine whether she is likely to respond to shunt surgery.  This procedure carries a 2% to 3% risk of meningitis.  I also explained that it would be reasonable to start with an outpatient lumbar puncture and if that is not sufficient we could proceed with admission for the spinal catheter protocol.
