Not always cysticercosis
The differential diagnosis of a lesion like this one should include:
- Bovine cysticercosis: First! The appearance of the lesion is compatible with a parasite vesicle. See entry on bovine cysticercosis.
- Other inflammatory lesions: Bacterial or Sarcocystis spp.
- Congenital cysts: Typically located in the valves.
Although the macroscopic image was suggestive of bovine cysticercosis, the histopathological study showed that it was a benign mesenchymal neoplastic proliferation, being in this case the most likely differential diagnosis a myocardial adenomatoid tumor.
