A 25 year-old man with AIDS presented with lethargy, headaches and numbness involving the left side. |
| Toxoplasmosis Brain Abscess: Axial CT scans with
contrast. Note the ring enhancing lesion in the region of the right
anterior thalamus. Also note that the right lateral ventricle is
trapped at the foramen of Monro, resulting in ipsilateral dilatation
of the anterior and temporal horns of the lateral ventricle.
Toxoplasma gondii is often seen as an opportunistic infection in patients with AIDS and other immunocompromised individuals. The lesions are often located deep in the basal ganglia and thalamus. Note, however, that this CT scan appearance is also consistent with tumor and other infectious etiologies. |
