Primary cranial vault lymphoma mimicking meningioma

Primary lymphomas of the cranial vault are rare; only six patients have been described in the literature. We report a 75-year-old woman who was admitted to our hospital after a focal seizure. CT showed a homogeneous mass which, on contrast enhancement, was similar to a meningioma. The tumour was excised and found to be a centroblastic, centrocytic non-Hodgkin's lymphoma. Treatment was completed with radiotherapy and chemotherapy.     

Primary non-Hodgkin's lymphoma of the cranial vault; MRI features before and after treatment

We present a case of a 71-year-old patient who was admitted with a subcutaneous scalp lump. MRI demonstrated a scalp lesion with infiltration of the bony calvarium and thickening of the dura, with irregular contrast enhacement. Biopsy revealed a malignant non-Hodgkin's lymphoma. After daily treatment with systemic chemotherapy and additional steroids over six months, a second MRI showed complete resolution of the mass. Primary non-Hodgkin's lymphoma of the cranial vault is extremely rare; imaging of a solitary and primary cranial vault non-Hodgkin's lymphoma by MRI before and after treatment has never been published before.

Primary malignant lymphoma of the urinary bladder: report of three cases and review of the literature

We report three cases of a primary malignant lymphoma of the urinary bladder. The radiological features revealed a sessile mass of the lateral wall for one case, a circumferential thickening in the second, and two separated masses of the bladder wall in the last case. Primary malignant lymphoma of the urinary bladder is extremely rare. From a review of the literature, the clinical and radiological findings are discussed. In this paper we report the first case of urinary bladder lymphoma presented on CT as multiple masses. Received: 24 June 1999; Revised: 30 November 1999; Accepted: 25 January 1999

儿童骨原发性非霍奇金淋巴瘤三例

儿童原发于骨的非霍奇金氏淋巴瘤（non—Hodgkin lymphoma，NHL）极为少见，临床上很难与其他儿童骨的恶性肿瘤鉴别。现报告3例经病理证实的儿童骨原发性NHL，并分析其影像特征。     

Malignant lymphoma of the cranial vault in an HIV-positive patient: imaging findings

We describe the CT and MR imaging findings in an HIV-positive patient with malignant non-Hodgkin's lymphoma of the cranial vault, a rare site for lymphoma involvement. Autopsy revealed lymphomatous bone lesions, lymphoma in the epidural space, and a large necrotic lymphoma in the soft tissue of the skull.     

Primary lymphoma of the breast: A report of two cases

Primary breast lymphoma (PBL) should be distinguished from secondary breast lymphoma arising in the setting of lymphoma elsewhere in the body. Multimodality imaging is key to diagnosing PBL, and imaging manifestations thereof may indicate PBL and alter the treatment course. Treatment options including chemotherapy, radiation therapy, and/or surgery depend on histology. We report two cases of PBL, illustrating the transformative impact that multimodality imaging may have on clinical management.     

原发性中枢神经系统恶性淋巴瘤(附10例病例报告)

目的：提高对原发性中枢神经系统恶性淋巴瘤(PCNSL)临床特征的认识。方法：回顾性分析经病理证实的10例PCNSL，结合文献对其发病机制、临床表现和治疗方法等进行探讨。结果：10例患者随访3～48个月，中位时间27.4个月。其中除手术外单纯放疗组、化疗加放疗组和干细胞移植治疗组的中位生存时间分别为11．4，39．7和40个月。结论：本病诊断难，病程短，预后差，加强以HD-MTX化疗为主的综合治疗是提高本病疗效的关键。
