There is a cortical cyst in the lower pole of the right kidney measuring 6.1 x 6.1 x 6.1 cm, with the upper thin posterior separation containing calcification 3 mm thick.  This is most probably benign Bosniak 2-2F. No suspicious renal mass, stone or hydronephrosis.  The unopacified renal collection system appears grossly normal.

Neurotoxoplasmosis, brain abscess caused by parasitic protozoan Toxoplasma gondii and close-up view of Toxoplasma gondii in bradyzoite stage, computer illustration. T. gondii is a species of parasitic protozoa that can be carried by all known mammals. It causes toxoplasmosis, a usually minor and self-limiting disease. It can, however, have serious or even fatal effects on an unborn foetus if the mother contracts toxoplasmosis during pregnancy. Also, it can cause abscesses of inner organs and brain in immunocompromised patients, such as in HIV-infected patients.
