Embolization of blood-supply artery followed by surgery for treatment of mesorectal Castleman's disease: case report and literature review

Preoperative Direct Puncture Embolization of Castleman Disease of the Parotid Gland: A Case Report

BACKGROUND

Castleman disease (CD) is an uncommon benign lymphoproliferative disease characterized by hypervascular lymphoid hyperplasia. We present a unique case of unicentric CD of the parotid gland treated by preoperative direct puncture embolization.

CASE PRESENTATION

A 27-year-old female patient was admitted for a right neck mass. Ultrasound examination and MRI scan documented a hypervascular mass within the right parotid gland. Preoperative embolization was performed by direct puncture technique: a needle was inserted into the core of the mass under both ultrasound and fluoroscopic guidance and SQUID 12 was injected into the mass under fluoroscopic control, achieving a total devascularization.

CONCLUSION

Preoperative direct puncture embolization was safe and effective and provides excellent hemostatic control during the surgical operation, limiting the amount of intraoperative bleeding.

Castleman disease: Report of a case and review of literature on role of preoperative embolization

Introduction

Castleman disease, which was first described by Dr. Castleman in 1954, is relatively rare and represents a spectrum of heterogeneous lymphoproliferative disorders with characteristic histological features on biopsy. It is classified based on body location and histology with variable clinical presentations. Its treatment depends on the subtype, and preoperative embolization for Castleman disease has rarely been discussed in the literature.

Presentation of case

A 22-year old man presented to the ENT clinic with a four-week history of a mass on the left side of the neck, which was associated initially with headache, fever, and fatigue for 2 days. Contrast tomography and magnetic resonance imaging revealed a hypervascular mass located at levels two and three of the left side of the neck with feeding vessels from the external carotid artery. Preoperative embolization was planned; however, the neurointerventionist considered it a lymph node that did not need embolization. Surgical excision was performed with relatively increased operative time and bleeding. A biopsy confirmed a hyaline-vascular type Castleman disease.

Discussion

We reviewed the evidence-based management of CD. We reviewed the available literature on the role of preoperative embolization in management.

Conclusion

Based on published articles and the hypervascular nature of the disease, we believe that preoperative embolization helps decrease morbidity.

•

Castleman disease is an angiofollicular lymph node hyperplasia and a form of lymphoproliferative disorder

•

Different disease types have different clinical presentation and management

•

Main treatment of unicentric castleman disease is surgical excision

•

Castleman disease lymph nodes are highly vascular and are prone to intraoperative bleeding and need for blood transfusion

•

Preoperative embolization can help reduce operation time and complications

Combinatorial treatment for unresectable unicentric Castleman disease

Unresectable, symptomatic unicentric Castleman disease (UCD) can represent a formidable therapeutic challenge. UCD masses are often highly vascularized offering the opportunity for therapeutic embolization. Herein, we report on 6 patients in which therapeutic embolization was combined with other medical interventions including surgery (n = 3), rituximab (n = 6), cryoablation (n = 2), and chemotherapy (n = 3). Five patients had significant tumor volume reductions (median: 83.2%; range: 76.7-100). All five responding patients had resolution of symptomatology. There were no serious complications in the patients who received embolization and proceeded to surgery. In conclusion, effective disease and symptom control can be obtained in patients with symptomatic, unresectable UCD by combining different therapeutic interventions.

Surgical resection for pelvic retroperitoneal Castleman's disease: A case report and review literature

Castleman's disease (CD) is a rare atypical lymphoproliferation disorder first reported in 1954. Clinically, CD is classified as unicentric or multicentric CD based on anatomical distribution. Unicentric CD primarily affects the mediastinum, and rarely affects the retroperitoneal location. The standard treatment for unicentric CD is complete surgical resection; however, this can be complicated by a high degree of attachment with other organs or hypervascularity. Preoperative angiography and embolization of the arteries that feed the problematic mass can reduce intraoperative bleeding in cases of CD with hypervascularity. In the present case report, a 44-year-old man who was found to have a pelvic retroperitoneal mass with calcification based on abdominal imaging results is discussed. Due to the hypervascularity of the mass, preoperative embolization was performed. The mass was completely resected without any complications. Additionally, a review of the literature on pelvic CD and preoperative embolization of CD was performed to provide an up-to-date reference on the management and outcomes of patients with CD.
