Parietal wall hydatid cyst presenting as a primary lesion

Area of Science:

• Parasitology
• Abdominal Imaging
• Surgical Pathology

Background:

• Hydatid cyst (echinococcosis) is a parasitic disease typically affecting the liver and lungs, prevalent in sheep-rearing regions.
• While common in specific areas, hydatid disease can manifest anywhere in the body, including unusual intramuscular locations.

Observation:

• A 54-year-old female farmer presented with a painless, growing mass in her left iliac fossa over six months.
• Initial ultrasound suggested a hydatid cyst; subsequent surgical excision was performed, preserving the cyst's integrity.
• Histo-pathological examination confirmed the diagnosis of a primary hydatid cyst in the abdominal intramuscular region.

Findings:

• The case highlights an uncommon presentation of hydatidosis in the abdominal wall musculature.
• Complete surgical excision of the intact cyst is essential for successful treatment.
• Postoperative albendazole administration is recommended to prevent recurrence.

Implications:

• Hydatid cysts should be considered in the differential diagnosis of cystic lesions, even in atypical locations.
• This case underscores the importance of thorough diagnostic workup and complete surgical intervention for hydatid disease.
• Effective management involves both surgical removal and appropriate medical therapy to minimize relapse risk.
