A 60-year-old man in Spain presented with headaches and behavioral changes, leading doctors to initially suspect metastatic brain cancer due to multiple lesions seen on CT scans. After ruling out malignancy through extensive testing, an MRI revealed the lesions were actually encapsulated tapeworm larvae, highlighting the diagnostic challenge of parasitic infections mimicking tumors.
Background
