Mr. A. H., age 44, had a generalized tonic-clonic seizure unexpectedly at work_ He had no history of seizures, trauma, infection, or other illness. Investigation revealed a tumor in the right parietal lobe. This was removed surgically, although the diffuse nature of the malignant mass prevented its complete elimination. Follow-up radiation treatment was recommended. After surgery, Mr. A. H. demonstrated considerable weakness and sensory loss on his left side. A few days after surgery, Mr. A. H. developed a bacterial infection at the operative site. The infection was eradicated quickly with treatment, but the tumor did not respond to radiation and chemotherapy. As a result, several tumors in the brain grew relatively large during the next 2 months.
Mr. A. H. developed severe headaches and diplopia and became increasingly lethargic, and his seizures increased in frequency despite anticonvulsant medication. He was given medication to reduce the frequency of vomiting.
Explain the specific rationale for each of his manifestations.

a tumor is a growth of abnormal cells in the brain tissue, in this case they are malignant cancer cells since their growth is very fast, some are primary that start directly in the brain and other metastatic that start in another part of the body, in the case of Mister AH always had primary symptoms.

Tumors in the brain can show various symptoms. These are some of the most common:

Headaches, usually in the morning

Nausea and vomiting

Changes in the ability to speak, hear or see

Balance or walking problems

Problems with thinking or memory

Weakness or longing to sleep

Changes in mood or behavior

Seizures

tumors can destroy brain cells which can cause inflammation and damage to parts of the body depending on where in the brain this is exerted, this also aggravates the symptoms.

Radiation therapy used to treat brain cancers increases the risk of brain tumors up to 20 to 30 years later.

In this case, he was causing this same reaction to Mr. AH, which may also have another type of tumor such as

Meningiomas and schwanomas are two other types of brain tumor. These tumors:

They occur in most cases between the ages of 40 and 70.

They are not usually cancerous, but they can still cause serious complications and death due to their size or location. Some are cancerous and aggressive.

the correct answer is b
