Isolated hydatid cyst of the diaphragm, a case report

INTRODUCTION: Hydatid disease mainly affect lung and liver. We report a very rare case of hydatid cyst of the diaphragm. PATIENT INFORMATION: A 25-year-old female presented with vague right hypochondrial pain for 2 months. Clinical Findings showed mild tenderness at right hypochondrial region, Ultrasound showed segment 7 hepatic cystic lesion of about 5 × 6 × 7 centimeters, relatively thick wall, with eccentrically coarse calcification. Computed tomography showed cystic lesion affecting segment 7 of the liver with rims of calcification, appearance is consistent with hydatid cyst of the liver. At laparascopy the liver was found to be normal with a bulging from the lateral border of the diaphragm. Postero-lateral mini-thoracotomy was performed and cyst was found to be inside. Resection was done with direct repair of the diaphragm. The histopathogical examination confirmed hydatid cyst of the diaphragm. CONCLUSION: Isolated hydatid cyst of the diaphragm is a very rare entity. Pre-operative diagnosis is mandatory to prevent unnecessary excessive incisions.
