Teacher:Given an abstract, indicate which of the provided candidate titles (Option1 and Option2) best describes it (respond with the text of the title, not option1/2).
Teacher: Now, understand the problem? Solve this instance: Abstract: An exceptional form of hepatic alveolar echinococcosis with metastasis of the right atrium is reported. This cardiac location of the parasitosis was revealed by attacks of pulmonary embolism which produced secondary pulmonary lesions. This case suggests that pulmonary metastases of alveolar echinococcosis of the liver might be due to the migration of parasitic clots from the hepatic veins.
Which is the apt title for the abstract? option1: Pulmonary embolism from a parasitic cardiac clot secondary to hepatic alveolar echinococcosis. option2: Sphenoid sinus mucocele masquerading as a skull base malignancy.
Student:
Pulmonary embolism from a parasitic cardiac clot secondary to hepatic alveolar echinococcosis.
