Article Abstract
Objective: Mature extragonadal teratomas, particularly at the pelvic extraperitoneal site, are rare. Herein, we report a case of paravaginal teratoma and fistula formation five years post-operation.
Case Report: A 23-year-old woman (G4P3A1) presented with a left paravaginal cystic tumor. After transvaginal tumor excision, histopathology revealed a paravaginal dermoid cyst. Five years post-operation, she returned with recurrent symptoms, including fever and perineal pain. Pelvic magnetic resonance imaging showed abscess at the surgical site, with tract-like extensions through the levator ani and vaginal wall. Treatment was administered without surgical intervention. Seven years post-operation, the patient underwent debridement of the left paravaginal abscess via the left perineal route. The patient was diagnosed with an abscess and an epidermal keratinous cyst with a vaginoperineal fistula. No recurrent abscess or fistula formation was encountered four years after debridement and fistulectomy.
Conclusion: Preoperative and postoperative counseling should be conducted with long-term follow-up for such patients.

BACKGROUND Non-traumatic bladder rupture, a rare yet potentially life-threatening condition, can stem from diverse factors such as malignancies, bladder inflammation, or bladder diverticulum rupture. Pelvic radiotherapy, in extremely rare instances, can lead to radiation cystitis and subsequent bladder fistula formation. Patients with such conditions often present with abdominal pain, hematuria, oliguria, and urinary ascites.

Background: Hereditary Hemorrhagic Telangiectasia (HHT) is an autosomal dominant disorder characterized by abnormal vascular formations across multiple organ systems, including the brain. While arteriovenous malformations (AVMs) are well recognized in HHT, non-AVM cerebrovascular malformations remain underreported and poorly understood manifestations of the disease.
Methods: A systematic review was conducted using multiple databases, applying a two-step screening process to exclude studies with insufficient, irrelevant, or incomplete data.
Intraoperative Pneumatocele Formation during Liver Transplantation for Polycystic Liver Disease: Successful Non-Operative Management.

Department of Hepato-Biliary-Pancreatic Surgery and Transplantation, Kanazawa University, Kanazawa, Ishikawa, Japan.
Introduction: Liver transplantation for polycystic liver disease (PLD) poses significant intraoperative risks due to the presence of a massively enlarged liver. We report a rare case of intraoperative pneumothorax and pneumatocele formation during total hepatectomy, which was successfully managed with a non-operative approach.
Case Presentation: A female patient in her 40s with a history of autosomal dominant polycystic kidney disease presented with progressive liver cyst enlargement (Gigot type III, Qian classification Grade 4), which led to decreased activities of daily living and intracystic hemorrhage.
Endoscopic vacuum therapy (EVT) offers an effective alternative for the treatment of anastomotic leakage. Current treatment options for leakage include conservative treatment, stent placement, or reoperation. However, conservative treatment often results in slow recovery and is frequently ineffective in severe cases.
