Question

Differentiate between Toxoplasmosis, CNS lymphoma, and PML in HIV patients.

a) Toxoplasmosis: Ring-enhancing lesions; CNS lymphoma: Solitary mass lesion; PML: White matter lesions
b) Toxoplasmosis: White matter lesions; CNS lymphoma: Solitary mass lesion; PML: Ring-enhancing lesions
c) Toxoplasmosis: Solitary mass lesion; CNS lymphoma: White matter lesions; PML: Ring-enhancing lesions
d) Toxoplasmosis: White matter lesions; CNS lymphoma: Ring-enhancing lesions; PML: Solitary mass lesion

Answer 1

Toxoplasmosis, CNS lymphoma, and PML are conditions that can occur in HIV patients. Toxoplasmosis is characterized by ring-enhancing lesions, CNS lymphoma presents as a solitary mass lesion, and PML is associated with white matter lesions.

Step-by-step explanation:

Toxoplasmosis, CNS lymphoma, and PML are all conditions that can occur in HIV patients. Here is the differentiation between the three:

1. Toxoplasmosis: It is characterized by ring-enhancing lesions in the central nervous system (CNS). These lesions are seen on imaging techniques like CT or MRI.
2. CNS lymphoma: It presents as a solitary mass lesion in the CNS. This means that there is a single mass or tumor-like growth in the brain or spinal cord.
3. PML: PML stands for progressive multifocal leukoencephalopathy. It is associated with white matter lesions in the brain. These lesions appear as areas of abnormal tissue in the brain's white matter.
