Ultrasound in the diagnosis of granulomatous liver disease

Abstract

Ultrasound is a widely used method of assessing the liver for space occupying lesions and, more recently, parenchymal liver disease. We have reviewed the ultrasound scans and reports of 11 patients with biopsy proven granulomatous liver disease. Multiple echogenic lesions 3-5 mm in diameter, each surrounded by an hypoechoic halo, were seen in the liver of all the patients and in the spleens of three patients. A specific diagnosis of granulomatous hepatitis was suggested at the time of scanning in seven patients. An abnormal liver was noted in the other four patients but no specific diagnosis was suggested. We believe that granulomata in the liver can be detected using ultrasound and, if the above appearances are seen during an ultrasound scan, a diagnosis of granulomatous hepatitis should be considered.
