CT and MRI are helpful for localizing and defining the morphologic features of hydatid cysts. Specific signs include calcification of the cyst wall, presence of daughter cysts, and membrane detachment. CT best shows wall calcification, whereas MRI depicts the exact anatomic location and nature of the internal and external structures.

MDCT exhibited various sternal variations and anomalies. Sternal foramen is a frequent minor anomaly and generally associated with sternal sclerotic bands. Early manubriosternal and sternoxiphoidal fusions can be seen in early adulthood without osteodegeneration. Double-ended xiphoid process and single xiphoidal foramen are frequent sternal variations. Awareness of MDCT appearances of sternal variations and anomalies provides a better differential diagnosis with pathologic conditions.
