Background: Hydatid disease is a zoonosis caused by the larval stage of Echinococcus granulosus, most often affecting the liver and lungs. Disseminated hydatidosis is rare, accounting for <10% of cases. Case Presentation: We present a 28-year-old male with paraplegia and abdominal pain. He was first diagnosed with hydatid disease at a government hospital three years earlier, and presented to us with only an ultrasound (US) report. No serology reports were furnished. He had deferred surgery due to financial constraints. At current presentation, US, computed tomography (CT), and magnetic resonance imaging (MRI) demonstrated multiple cysts across the pelvis, retroperitoneum, spine, mediastinum, neck, and extremities. Imaging morphology was consistent with WHO-IWGE CE1– CE3 hydatid cysts. Differentials including abscess, cysticercosis, necrotic metastases, and lymphangioma were ruled out based on absence of contrast enhancement, calcification pattern, and clinical correlation. Treatment and Outcome: Surgery was advised but declined; PAIR was contraindicated due to multivesicular bone and spinal cysts. The patient was managed with oral albendazole. Follow-up data is currently unavailable. Conclusion: This case highlights disseminated hydatid disease with unusual spinal and soft-tissue involvement. Multimodality imaging was pivotal for diagnosis and treatment planning. Awareness of imaging features is essential for timely recognition and management.
