Chronic granulomatous disease: value of the newer imaging modalities

Clinical and imaging considerations in primary immunodeficiency disorders: an update

Primary immunodeficiencies are a group of genetically determined disorders with diverse presentations. The purpose of this review is to provide a practical and brief description of a select number of these diseases and to discuss the important role the radiologist can have in making an early diagnosis and in detecting and following disease complications. The role of diagnostic imaging and informed performance and interpretation are vital in the diagnosis, surveillance and management of all primary immunodeficiency disorders.

Evaluation of the gastrointestinal tract in the child: CT, MRI, and isotopic studies

The gastrointestinal radiologist no longer has to rely on indirect signs of extraluminal and solid organ pathology. With the use of the newer imaging modalities, including computed tomography, magnetic resonance imaging, and isotopic techniques, the entire abdomen and its contents can be directly visualized. Pathology, its extent and its effect on adjacent structures, can be readily appreciated.

Hepatic abscesses in the immunocompromised patient: role of CT in detection, diagnosis, management, and follow-up

Newer cytotoxic and immunosuppressive agents and more aggressive oncologic treatment protocols have resulted in an increased incidence of opportunistic infections in the immunocompromised host. Clinical symptoms and laboratory data are often nonspecific and definitive diagnosis may be difficult to establish. The role of CT in the detection, diagnosis, management, and follow-up of various hepatic opportunistic infections in 9 immunocompromised hosts is presented. In 5 of 6 patients, CT-guided needle aspiration resulted in definitive diagnosis. In 3 patients, surgical intervention was obviated by abscess drainage using CT guidance. There is clearly a role for CT not only in the detection but also in the definitive diagnosis, treatment, and follow-up of abscesses in the immunocompromised host.
