The imaging diagnostic criteria of AIDS-related cerebral toxoplasmosis in China

Abstract

The high mortality of aquired immune deficiency syndrome (AIDS)-related cerebral toxoplasmosis is one of the serious complications affecting the survival and prognosis of AIDS patients. The most important reason is the difficulty to diagnose. The gold standard for diagnosis of the disease is biopsy of brain tissue. However, this method is not easy to carry out clinically. The diagnostic efficiency of serum and cerebrospinal fluid antibody titers, polymerase chain reaction (PCR) and other methods are low. Although the imaging manifestations of cerebral toxoplasmosis in AIDS are variable, there are some characteristic features. It is very important to correctly recognize its characteristic imaging features and use related imaging methods to help diagnose this disease. The purpose of this paper is to provide consensus for the imaging characteristics of AIDS-related cerebral toxoplasmosis.
