What is the CPA in the brain?
What is the CPA in the brain?
Cerebellopontine angle tumors (CPAs) occur between the lower part of the brain and the brain stem. Most CPAs are benign, but can cause nerve damage or compress the brain stem if not treated. About 90 percent of the time, the first symptom is hearing loss in one ear, accompanied by tinnitus, ringing in the ears.
What causes lesions on the cerebellum?
Brain lesions can be caused by injury, infection, exposure to certain chemicals, problems with the immune system, and more. Typically, their cause is unknown.
What types of problems may result when lesions occur in the cerebellum?
Damage to the cerebellum can lead to: 1) loss of coordination of motor movement (asynergia), 2) the inability to judge distance and when to stop (dysmetria), 3) the inability to perform rapid alternating movements (adiadochokinesia), 4) movement tremors (intention tremor), 5) staggering, wide based walking (ataxic gait …
Which nerve can be affected by the Cerebellopontine Tumour?
The most common presenting symptoms of lesions involving the CPA include hearing loss, tinnitus, dizziness, vertigo, headaches, and gait dysfunction. Hearing loss is mostly unilateral sensorineural and is due to the involvement of the cochlear nerve.
What causes a lesion on the cerebellum to slow worsen?
The slow worsening suggests that the cause of the lesion is not vascular but is probably due to a tumor. The papilledema suggests a space taking phenomenon which also explains the headache and vomiting. A cerebellar hemangioblastoma was discovered and removed.
What are the signs and symptoms of cerebellar disease?
The abnormal reflexes and tone are consistent with cerebellar disease. Intention tremor, abnormal finger-to-nose/heel-to-shin tests and broad-based gait on the right all indicate a right cerebellar lesion. Neurological signs appear on the same side as the lesion since the cerebellum functions largely ipsilaterally.
