Clinical features of intracranial giant lymph node hyperplasia / 肿瘤

ABSTRACT

Objective: To investigate the clinical features of intracranial Castleman's disease, and to improve the understanding of the disease. Methods: The clinical features of one case of intracranial mixed type Castleman's disease, who was diagnosed in Department of Neurosurgery, Zhujiang Hospital, Southern Medical University in February 9, 2017, were retrospectively analyzed, and the relevant literatures about intracranial Castleman's disease were reviewed. The PubMed, Embase, Ovid, Cochrane, Wanfang Database and China Journal Full-text Database were searched using the keywords including "Castleman", "Intracranial"and "Central nervous system" for related literatures published between January 1, 1980 and January 31, 2017. Results: A 32-year old female was admitted because of headache for one month. CT examination showed an irregular and well-defined hyperdense lesion in the right temporo-parietal area with surrounding extensive edema and this mass was markedly contrast enhanced. Laboratory examination revealed anemia and hyperimmunoglobulinemia. The mass was removed completely by surgical resection. Postoperative pathology examination revealed mixed type Castleman's disease in the right temporo-parietal area. MRI was performed 3 months after the surgery. No residual tumor and recurrence were demonstrated. Seventeen related case reports were retrieved and 20 cases of intracranial Castleman's disease were reported. Among total 21 cases, there were 7 males and 14 females, ranging from 8 to 82 years old, and the median age was 47 years old. The mass arised from the dura matter or leptomeninges, and the most common sites of origin were located at the cerebral convexity and the parafalcine. The most common clinical features were seizures and headache. Radiographically, the previously reported cases presented as a homogeneously enhanced extra-axial well-defined mass with a marked peritumoral edema. Conclusion: Intracranial Castleman's disease is a rare clinical condition. The diagnosis can be made in combination with clinical findings and the laboratory examination.
