The pulmonary embolism detected in our case may probably have resulted, on the one hand, from the accidental injury to the case's inferior vena cava during earlier liver surgery which may have allowed the spread of daughter cysts within systemic circulation.
These nonenhancing multiloculations had low signal intensity on T1-weighted and high signal intensity on T2-weighted images compatible with daughter cysts. Intercystic spaces were filled with material, which was isointense with muscle tissue on T1-weighted and hyperintense on T2-weighted images, suggesting hydatid sand.
