A primary spinal hydatid cyst.

Area of Science:

• Medicine
• Parasitology
• Neurosurgery

Background:

• Hydatid disease, caused by Echinococcus granulosus, is typically acquired through fecal-oral contamination.
• Spinal hydatid cysts are rare, accounting for less than 1% of all hydatid disease cases, and often lead to poor prognoses due to neural compression.
• Management of vertebral hydatidosis is challenging due to high recurrence rates and the need for effective eradication strategies.

Observation:

• A case of primary extradural and paraspinal hydatid cyst (HC) was diagnosed preoperatively using magnetic resonance imaging (MRI) in an otherwise healthy patient.
• Histopathology confirmed the diagnosis postoperatively.
• The patient underwent surgical removal of the cyst followed by anthelminthic medication.

Findings:

• Initial surgical removal and anthelminthic treatment led to satisfactory recovery but were followed by recurrence after one year.
• A second surgery and a prolonged course of anthelminthic medication resulted in a recurrence-free period of one year.

Implications:

• This case underscores the complex management of spinal hydatid cysts, emphasizing the potential for recurrence even after seemingly complete treatment.
• The study suggests that prolonged anthelminthic therapy may be crucial in preventing recurrence.
• Further research is needed to establish the definitive efficacy of anthelminthic use post-surgery for spinal hydatid disease.
