Primary Paraspinal Hydatid Cyst in a Patient Presenting with Low Back Pain: A Case Report

Area of Science:

• Medical imaging
• Parasitology
• Spinal surgery

Background:

• Primary paraspinal hydatidosis is an uncommon parasitic infection.
• Low back pain with red-flag symptoms warrants a broad differential diagnosis.

Observation:

• A 54-year-old man presented with low back pain and fever, with a palpable lumbar mass.
• Normal radiographs contrasted with MRI findings of a multicystic mass at L2-L4.
• Surgical excision confirmed the diagnosis of a hydatid cyst.

Findings:

• The case highlights a rare instance of primary paraspinal hydatidosis.
• Diagnostic imaging, particularly MRI, was crucial in identifying the cystic mass.
• Surgical confirmation is definitive for hydatid cyst diagnosis.

Implications:

• Clinicians should consider primary paraspinal hydatidosis in patients with suggestive symptoms, especially in endemic regions.
• Increased awareness can lead to earlier diagnosis and appropriate management of this rare condition.
• This case underscores the importance of considering parasitic infections in spinal pathology.
