A Case of Ruptured Pulmonary Hydatid Cyst of the Liver and Review of the Literature

Pulmonary Cystic Echinococcosis: A Ruptured and Infected Cyst Presenting As Pyopneumothorax

In this report, a case of 62-year-old female is described who came to the hospital with chief complaints of breathlessness and productive cough with salty whitish expectoration, which she had for two months, along with fever and right-sided chest pain, for three days. The case was identified as a ruptured pulmonary hydatid cyst with pyopneumothorax using contrast-enhanced computed tomography and chest X-ray. This was further supported by the Echinococcus antibody IgG test. Right thoracostomy, the placement of an intercoastal drain, and four days of continuous aspiration of 750 ml of serous fluid were used for managing the case. Following this, oral albendazole was used as a conservative measure.

Acquired right-sided diaphragmatic hernia in a patient with retroperitoneal hydatidosis: a case report and review of the literature

Background

Diaphragmatic hernia is primarily congenital in origin and has potentially devastating pulmonary complications. Acquired diaphragmatic hernia as a complication of hydatid disease remains a rare clinical entity. Retroperitoneal hydatidosis, in particular is an exceptionally rare cause behind a similar presentation. This paper aims to present the first case of acquired diaphragmatic hernia likely caused by eroding retroperitoneal hydatid cysts and provide a succinct literature review regarding the causative association between hydatid disease and diaphragmatic defects.

Case presentation

A 71-year-old Saudi man, with a history of hydatid disease involving several areas including the retroperitoneum, presented with multiple episodes of shortness of breath and abdominal pain of 10 months’ duration. Computed tomography scans of the chest and abdomen demonstrated the presence of a large diaphragmatic defect, with herniation of bowel loops into the chest cavity. Initially, the patient underwent a diagnostic laparoscopy which was then converted to a posterolateral thoracotomy to repair the defect.

Conclusions

The ability of hydatid disease to involve several body organs makes diagnosis and management of resultant complications a challenge in some cases, like ours. Knowledge about a reported rare complication could enable early detection and management to avoid serious complications, including abdominal viscera incarceration and strangulation.
