Lymphangioma of the gallbladder in adults: review of the literature and a case report

A comprehensive exploration of gallbladder health: from common to rare imaging findings

This comprehensive review explores a wide range of imaging findings associated with the gallbladder (GB), from anatomic variants to rare diseases. Through an in-depth review of diagnostic modalities including ultrasound, magnetic resonance cholangiopancreatography, CT, and MRI, we aim to highlight the crucial role of imaging techniques in diagnosing GB disorders, as congenital anomalies, inflammatory diseases, neoplasms, and surgical complications. Employing a detailed analysis and comparison of imaging findings across various modalities, this review seeks to improve diagnostic accuracy for GB-related pathologies, facilitating optimal patient management.

Gallbladder fossa lymphangioma encasing the common bile duct: a case report and review of the literature

Introduction

Lymphangiomas are rare low-flow lymphatic vessel malformations mostly diagnosed in childhood. Among the abdominal lymphangiomas, the gallbladder lymphangioma is a rare presentation, and only a few cases have been reported till date, of which majority were cystic lymphangiomas.

Case presentation

The authors present a case of a 48-year-old female with abdominal pain and normal physical examination and laboratory findings. On the performed imaging, a multiloculated cystic lesion, located in the gallbladder fossa, was found. The patient underwent open cholecystectomy, and surprisingly, the cyst extended to the common bile duct, which was separated cautiously. The cyst was resected, and the histopathological findings confirmed cystic lymphangioma.

Conclusion

The cystic lymphangioma of the gallbladder can be asymptomatic, although most of the literature has reported abdominal pain. The diagnosis of lymphangioma is complicated, especially when intra-cystic hemorrhage happens. Ultrasonography, computed tomography, and magnetic resonance imaging are usually performed. The surgical excision of the cyst and the gallbladder is the treatment of choice. Although bile duct involvement is extremely rare, it should be considered during the surgery.

Gallbladder lymphangioma simulating liver hydatid cyst: A case report

Introduction and importance

Gallbladder lymphangiomas are very-rare, yet benign tumors that start developing in early life. Those tumors often go unnoticed until adulthood as they grow into a larger size or a complication happens. Despite its rarity, suspicion for the diagnosis should be maintained by the physicians.

Case presentation

A 14-year-old female patient presented to the hospital complaining of right upper quadrant abdominal pain of one month duration. Physical examination showed mild upper quadrant tenderness. Serology testing for the patient only showed eosinophilia. Computed tomography showed a large non-enhancing cystic lesion attached to the gallbladder. Presumptive diagnosis of hydatid cyst was made, and the patient was treated accordingly. Histological analysis of mass showed dilated lymphatic vessels, hence the shift in diagnosis towards a lymphangioma was made.

Clinical discussion

Gallbladder lymphangioma are usually asymptomatic, but they can present with pain, nausea and vomiting. Multiple complications had been reported including compression of the nearby structures, intra-abdominal infection, rupture, torsion or hemorrhagic transformation. Surgical removal of the mass is the treatment of choice.

Conclusions

Right upper quadrant pain can be the presenting symptom of liver pathology. Histological assessment is needed to confirm the diagnosis which will show dilated lymphatic vessels.

•

Gallbladder lymphangioma is a very-rare tumor which is often misdiagnosed by a more common pathology.

•

Oral and Intravenous contrast computed tomography will show a non-enhancing cystic lesion.

•

Surgery is the treatment of choice, and histological assessment will show dilated lymphatic vessels.

•

To our best knowledge, this is the first reported case in Palestine, among the 10 other cases reported world-wide.

Laparoscopic excision of a lymphangioma of the cystic duct

Lymphangiomas are benign tumors that originate from malformations of the lymphatic vessels. They are rarely seen in adults and are extremely rare in the cystic duct. Herein, we report the case of a 48-year-old woman who presented with a cystic lymphangioma that originated in the cystic duct and was excised laparoscopically. Preoperative imaging revealed the cystic and benign nature of the lesion. Laparoscopic abdominal exploration and excision of the 10-cm cystic lymphangioma were performed. Four trocar sites were used, and the excision was achieved using clips and electrocautery. The laparoscopic excision of these benign masses is safe and efficacious in experienced hands. This procedure requires preoperative planning and must be individualized.
