ABSTRACT

Hepatocellular carcinoma (HCC) is usually diagnosed at an advanced stage, when little remedy could be offered. There is a need for relatively affordable, available and noninvasive tests for diagnosis, staging and detection of metastasis among individuals at risk. A clinical, chest radiographic (CXR) and abdominal ultrasonographic examination was carried out to detect and evaluate the pattern of metastasis among 53 untreated patients. One patient had clinical paraparesis with no outward evidence of metastasis. CXR revealed lung metastasis in 11 (20.8%), with multifocal deposits and bilateral involvement in 10 (18.8%), and unilateral single deposit in one. Two (3.8%) patients had perihilar lymphadenopathy and consolidation, respectively, while 18 (34%) patients had elevated right hemidiaphragm and four (7.5%) had pleural effusion. One had right basal pneumonitis, multiple cavitatory lesions in the lung fields and soft-tissue wasting. No abnormality was seen in 17 (32.1%) cases.
