Question: Brain Lesions some with enhancement?


 cjs - Tue Oct 13, 2009 9:45 pm

My son was having ringing in his ears, that progressed to some equilbrium problems and vision problems. The vision problems were with the right side. We had MRI after about 3 weeks. Found 10-12 brian lesions some with enhancment. The largest was about 1.4 cm in the vicinity of the afementioned right occipital lobe with a couple simial lesions are seen in immediate vicinity and one addiotnal simila lesion is een in the frontal lobe on the left near the midline. We went to hosp and had biopsy of the frontal lobe. This is do show anything definte. We have since repeated MRI in July 09 showed basicaly the same. stated 1.5 cm rounded lesion with peripheral ring enhancement remains in the rt frontal lobe. Then proceded to Spinal tap. This came back negative... Should we continue with MRI now to see if the lesions are still there... My son passed on 10/11 and went to the ER only thing out of Range WBC 15800? Left ER with no reason why he passed out.. He had been drinking the night before BAC was less than 10, neg drug screen, CMP all normal...

User avatar Hi,
There are a number of lesions that reportedly show enhancement ('ring enhancement ') on a MRI brain scan.

- Gliomas, lymphomas,

- Brain Metastases,

- Abscesses (pyogenic and abscess caused by atypical organisms, such as Rhodococcus,Mycobacteria, Listeria,Nocardia, Actinomyces, etc ),

- Abscesses due to Fungi(Cryptococci, Histoplasma,zygomycosis, Aspergillus,Coccidioides, etc ),

- Certain parasitic infections (amoebiasis,neurocystircercosis,echinococcosis)

- cerebral Infarction

- brain Contusions

- Demyelination disorders(acute encephalomyelitis,multiple sclerosis) and

- Resolving hematomas.

* In an immunocompetent patients, Toxoplasma encephalitis is to be considered as a priority.
* in an immunocompromised patients, metastatic deposits(secondaries) assume priority.

A high total WBC count suggests an abscess.

I hope this information may be of use to you.
Good day!
