Isolated Solitary Hydatid Cyst of the Left Hemidiaphragm: Case Report and Management Challenge

Abstract

Hydatid disease of the diaphragm caused by Echinococcus granulosus is a rare entity. Its localization poses a diagnostic challenge, especially if the diaphragmatic hydatid cyst is isolated and on the left side. Case presentation: We present a case of a 56-year-old male farmer with a hydatid cyst located in the left copula of the diaphragm. However, the radiological investigations could not accurately determine the location of the cyst. While the ultrasound suggested that it was present within the chest cavity, the computed tomography indicated that it was in the abdominal cavity. Consequently, the patient had to undergo a laparoscopic exploration, which had to be converted to a laparotomy. During the operative intervention, the diaphragmatic seat of the cyst was confirmed, and it was completely excised. The diaphragmatic defect was also repaired successfully, and the postoperative course was unremarkable. The patient was prescribed albendazole after the operation to prevent recurrence. Conclusion: Uncertainty regarding the location of a diaphragmatic hydatid cyst can affect the surgical strategy, and the final diagnosis is often made during surgery.
