PURPOSE: The aim of this study was to document the sonographic appearance and dimensions of the liver and spleen in patients affected by type I glycogen storage disease and to correlate those findings with laboratory data to evaluate the potential role of sonography in diagnosing that disease.
METHODS: Fourteen patients (age range, 3-26 years; 10 patients younger than 18 years) with type I glycogen storage disease proved by liver biopsy were studied prospectively with gray-scale sonography, color Doppler sonography, and spectral analysis. The liver, kidneys, spleen, portal system, hepatic veins, and hepatic arteries were evaluated. Laboratory data were correlated with sonographic findings.
RESULTS: In 13 (93%), of 14 patients, the liver was enlarged, and in 11 patients (79%), hepatic echogenicity was increased. In 9 patients (64%), both kidneys were enlarged, and in 6 cases (43%), the spleen was enlarged. In all patients, flow in the portal, splenic, and superior mesenteric veins was hepatopetal, and flow in the hepatic veins was triphasic. In 5 patients (36%), both triglyceride and total cholesterol levels were higher than normal. No focal hepatic lesions were identified. Analysis found no significant association between sonographic findings and laboratory data.
CONCLUSIONS: The most frequent sonographic findings in patients with type I glycogen storage disease were hepatomegaly, increased hepatic echogenicity, and enlarged kidneys. Sonography may help in the diagnosis of type I glycogen storage disease, but a liver biopsy is required for a definitive diagnosis.
