Intraoperative air leak test was useful for the detection of a small biliary fistula: A rare case of non-parasitic hepatic cysts with biliary communication

Doubly complicated: A case of massive non-parasitic liver cyst presenting with dyspnea and inferior vena cava compression: A rare case report

INTRODUCTION AND IMPORTANCE

Simple hepatic cysts, common benign liver conditions, are increasingly detected incidentally due to advancements in imaging technologies. While typically asymptomatic, complications such as compression of neighboring structures can arise, presenting unique diagnostic and management challenges. We present a doubly complicated case of a massive non-parasitic liver cyst in a 61-year-old female patient, manifesting with dyspnea and compression of the inferior vena cava.

CASE PRESENTATION

A 61-year-old female with a history of treated hypertension presented with worsening dyspnea over six months. Physical examination revealed a large, painless abdominal mass, and imaging confirmed a 20 cm cystic liver mass compressing the inferior vena cava and exerting a mass effect on the diaphragm. Surgical exploration and deroofing of the cyst led to successful resolution.

CLINICAL DISCUSSION

The presentation of dyspnea in non-parasitic liver cysts is rare but notable, highlighting the importance of considering hepatic etiologies in respiratory symptoms. Imaging modalities such as ultrasound and CT play crucial roles in diagnosis, while MRI aids in ruling out biliary-cystic fistulas. Surgical management, particularly subcostal laparotomy, remains a viable option for complex cases.

CONCLUSION

This case underscores the need for heightened awareness of atypical presentations of non-parasitic liver cysts and the significance of imaging in diagnosis. Subcostal laparotomy, though associated with limitations, remains valuable in select cases. Further research comparing surgical approaches is warranted to optimize management strategies for symptomatic non-parasitic liver cysts.

Spontaneously ruptured hepatic cyst treated with laparoscopic deroofing and cystobiliary communication closure: A case report

The rupture of a nonparasitic hepatic cyst with biliary communication is rare. We report the case of a patient with a hepatic cyst with biliary communication that spontaneously ruptured and was successfully treated by laparoscopic deroofing and closure of the communication. A 61-year-old woman presented at our hospital with a chief complaint of right upper abdominal pain. Enhanced abdominal CT showed a collapsed hepatic cyst and fluid collection. Drip infusion CT cholangiography showed contrast medium pooling in the collapsed cyst. Therefore, hepatic cyst rupture with biliary communication was diagnosed, and laparoscopic deroofing and closure of the communication were performed. The postoperative course was uneventful, and the patient was discharged on postoperative day 6. In cases of hepatic cyst rupture, even in the presence of biliary communication, laparoscopic deroofing and closure of the communication should be recommended as the first-choice treatment.
