    Notes: Abstract. Retention of surgical sponges is rare. They cause either an aseptic reaction without significant symptoms or an exudative reaction which results in early but nonspecific symptoms. Computed tomography is very useful for recognition of retained sponges. The appearance of retained sponges is widely variable. Air trapping into a surgical sponge results in the spongiform pattern which is characteristic but unfortunately uncommon. A low-density, high-density, or complex mass is found in the majority of cases, but these patterns are not specific. Sometimes, a thin high-density capsule may be seen. Rim or internal calcification is a rare finding. Finally, a radiopaque marker is not a reliable sign. Differentiation from abscess and hematoma is sometimes difficult.

    MRI of abdominal hydatid disease (1994)
    Springer
    Abdominal imaging 19 (1994), S. 489-494

    Notes: Abstract Seventy hydatid cysts in 30 patients were studied with magnetic resonance imaging (MRI) and computed tomography (CT); all cases were confirmed surgically. MRI detected all cysts when confined to solid organs, whereas small-sized cysts (≤2 cm) may be missed when located in the peritoneal cavity. Hydatid cysts of less than 3 cm (noncomplicated) present no specific findings of hydatid disease. MRI findings suggesting hydatid disease demonstrate a relatively thick hydatid cyst wall, daughter cysts, and germinal membrane detachment. T2-weighted images proved to be superior to T1 or PD-weighted images in demonstrating hydatid cyst wall thickness, germinal membrane detachment, and daughter cysts. In all spin-echo sequences, the maternal cystic content presented much higher signal intensities than that of daughter cysts. This difference in signal intensity is more obvious in T2 weighted images, except in complicated, infected cases. CT proved to be superior to MRI in demonstrating wall calcifications.
