FIGURE 1: Presence of cystic lesions in both cerebral hemispheres, the largest of which is 2 cm in size, without multivesicular contrast enhancement. A 46-year-old male patient presented with a headache that persisted for 1 year. Physical examination revealed no abnormalities. Contrast-enhanced cranial computed tomography (CT), requested with a provisional diagnosis of a mass, revealed cystic lesions in both cerebral hemispheres, the largest of which was 2 cm in size, without contrast enhancement (Figure 1). Magnetic resonance imaging of the patient's brain revealed multiple round, multivesicular T1-hypointense and T2-hyperintense lesions in both cerebral hemispheres (Figure 2). These findings were significant with respect to hydatid cysts. Non-contrast thoracic CT was performed during the patient's general physical examination. A 22 × 10 mm hyperdense, septate cystic lesion was noted in the right teres major muscle (Figure 3). Postoperatively, a hydatid cyst was confirmed pathologically.
