A case of gall bladder haematoma observed echographically in a dialysed patient is reported. The observation was probably related to the administration of anticoagulants during dialysis.
The echographic study of the gastrointestinal tract is hampered by the presence of gas that prevents the long-range penetration of the ultrasound beam. However the presence of a mass with a central echogenic region surrounded by a sonolucent wall of over 1.5 cm is characteristic of intestinal pathologies. A study of 23 patients with gastrointestinal disorders in whom echography revealed specific pictures is presented.
Ultrasound during pregnancy is a valid method to determine foetal growth. Occasionally abnormalities are detected. We report a case in which an echographic study showed a placental chorioangioma. We underline ultrasound patterns and examine clinical features.

Sonography is a safe and suitable diagnostic tool; to date it appears to be the most valuable method for detecting renal cystic lesions. In particular ultrasound examination, if a wider district is screened, can demonstrate the coexistence of the cystic disease in different organs. The Authors report a case of renal polycyctic disease in which the sonographic examination was extended to the entire abdomen disclosing simultaneous involvement of the kidneys and the liver.
Gastric leiomyoblastoma is a rare stomach tumour arising in the muscular tunica. Its prevalently oesophytic development makes diagnostic techniques that mainly concentrate on the intestinal lumen (digestive X-ray and endoscopy) of little use. A case is reported in which echography pointed diagnosis in the right direction by analysing a number of typical symptomatological signs.
