Epidural Extramedullary Plasmacytoma Successfully Treated with Surgical Excision and Bortezomib, Cyclophosphamide and Dexamethasone.

Plasma cell neoplasms are common, accounting for more than 1% of all malignancies. Its most common form is multiple myeloma, but others, such as extramedullary plasmacytoma (EMP), exist. Spinal cord compression secondary to these pathologies is not uncommon, however, adjacent bone involvement is usually present. Spinal cord compression caused by isolated epidural EMP is extremely rare, with only one case reported to date. We describe the case of a 75-year-old female patient that presented with paraparesis, due to an isolated epidural EMP associated with light chain amyloidosis. She was treated with surgical decompression and neoadjuvant chemotherapy, and is currently with a 15-month disease-free period.

Melanoma Originating from the Dura-Mater: A Case Report and Review of the Literature.

Melanomas originating from the dura-mater are extremely rare tumors. The diagnosis is complex, and usually only made after excluding other entities. The prognosis is poor, with average free-disease survival of 20 months, after treatment with complete surgical excision and adjuvant therapy. We report the case of a 41-year-old asymptomatic patient, presenting with a subcutaneous mass in the left parieto-occipital region, later diagnosed as a primary dura mater melanoma. Treatment included complete microsurgical excision, radiotherapy and adjuvant immunotherapy. Therefore, due to the rare nature of the disease and its high lethality, correct diagnosis and treatment are medical challenges.

Primary central nervous system lymphoma in elderly: An illustrative case of the new role of surgery and integrative medical management.

Background: Primary central nervous system lymphoma (PCNSL) is a rare, aggressive non-Hodgkin lymphoproliferative neoplasm. Surgery is traditionally limited to biopsy due to past studies, but recent strong evidence continues to challenge this status quo in selected patients. Here, the authors characterize a case to illustrate the potential role of surgery and foster research on integrative medical management approaches for this disease. Case Description: A 73-year-old woman was admitted to the hospital with aphasia and confusion. Neuroimaging suggested a lymphoproliferative process. The patient underwent cytoreductive surgery to resect the lesion. Microscopically, large infiltrating lymphoid cells that induced brain tissue damage were observed, and a diagnosis of diffuse large B-cell lymphoma was made based on immunohistochemistry. The patient evolved clinically post surgery. A complete response to further chemotherapy maintained the patient's clinical recovery. Conclusion: This rare case highlights the potential of surgical intervention in the management of selected patients with PCNSL. The authors also underscore the recent, meta-analytic evidence on surgery followed by combined chemotherapy for the management of specific cases. The reported recovery in an elderly patient is noteworthy and adds to the literature on this rare subtype of brain tumors. Future research should consider investigating a potential profile of candidates for resection and combined chemotherapy in PCNSL.

Transorbital Cavernous Sinus Direct Puncture : Alternative to treat dural arteriovenous fistula.

INTRODUCTION: The authors present a retrospective series of their clinical experience in the treatment of cavernous dural arteriovenous fistulas (DAVF) by direct transorbital puncture of the cavernous sinus as an alternative to the endovascular approach. METHODS: Between October 2012 and September 2014, eight patients harboring cavernous DAVF underwent percutaneous treatment by direct transorbital puncture of the cavernous sinus at three institutions. All patients presented with ocular symptoms. Standard endovascular approaches, including transvenous and transarterial routes, were primarily attempted without success in all cases. Direct puncture was performed through two different approaches, namely inferolateral and superomedial. The entry point was the inferior and superior eyelid, respectively. Embolization was performed with coils or Onyx (Covidien, Irvine, CA). Immediate and late angiographies were used to evaluate the occlusion of the fistula. RESULTS: Of the patients seven had complete occlusion of the cavernous DAVFs noted on the immediate and follow-up angiograms and one patient had residual filling but reduction of the shunt resulted in clinical improvement. None of the patients had worsening of neurological function. One case was complicated by inadvertent internal carotid puncture but without clinical manifestations. One patient experienced postoperative superior ophthalmic vein thrombosis. CONCLUSION: In very specific cases, when endovascular access is not possible or fails to occlude cavernous DAVF, direct transorbital puncture of the cavernous sinus was shown to be feasible, safe and very effective.
