Multiple ring enhancing lesions on CT in HIV pt can be what two things

Answer 1

Multiple ring enhancing lesions on CT in an HIV patient can be indicative of Toxoplasmosis and Primary Central Nervous System Lymphoma (PCNSL).

Step-by-step explanation:

In an HIV patient, multiple ring enhancing lesions on a CT scan can be indicative of two conditions: Toxoplasmosis and Primary Central Nervous System Lymphoma (PCNSL).

Toxoplasmosis is an opportunistic infection caused by a parasite called Toxoplasma gondii. It commonly affects individuals with weakened immune systems, such as those with HIV. Ring enhancing lesions on CT scans are a characteristic feature of brain toxoplasmosis.

PCNSL is a type of non-Hodgkin lymphoma that primarily affects the central nervous system. It can occur in HIV patients and is also associated with ring enhancing lesions on imaging studies.
