摘要:

OBJECTIVE AND IMPORTANCE:The preservation of oculomotor nerves is one of the most significant issues regarding the resection of meningiomas around the cavernous sinus.CLINICAL PRESENTATION:We report the case of a patient whose oculomotor nerve was fenestrated, caused by a large meningioma around the cavernous sinus. The nerve function remained intact until surgery.INTERVENTION:During surgery, one trunk of the fenestrated nerve behind the tumor was sacrificed. The fenestrated shape of the nerve led us to the misjudgment that the preserved other trunk located along the upper margin of the tumor was the whole nerve.CONCLUSION:Although fenestrated oculomotor nerves may be rare, their possibility should be kept in mind during surgery around the cavernous sinus.

摘要:

OBJECTIVE AND IMPORTANCE:The intradural extension of a sacrococcygeal teratoma is rare and has been reported previously in only two cases. We present a case of a sacrococcygeal teratoma with an intradural and extramedullary extension.CLINICAL PRESENTATION:The patient was a full-term female infant, born with a sacral mass. Ultrasonography, computed tomography, and magnetic resonance imaging showed an intraspinal extension.INTERVENTION:The operation confirmed the extension of the mass up to the T4 level, and total tumor removal was achieved. The pathological examination showed a mature teratoma.CONCLUSION:The postoperative course was uneventful, and at the 3-year follow-up examination, the patient had experienced normal growth without deficit in the lower limbs but had a neurogenic bladder. Magnetic resonance imaging disclosed no tumor recurrence. This case represents the third case in the literature of an intradural extension of a sacrococcygeal teratoma and the first one with an extramedullary component so extensive.

摘要:

OBJECTIVE AND IMPORTANCE:Considered benign and malformative in nature, enterogenous cysts are predominantly spinal lesions. Although recurrences have been reported, especially in the rare intracranial examples, craniospinal dissemination has never been described.CLINICAL PRESENTATION:We report a 63-year-old woman who presented 16 years previously with a histologically typical enterogenous cyst of the cerebellum. Fourteen years after its incomplete excision, numerous supratentorial, infratentorial, and spinal subarachnoid cysts were detected. A histological examination revealed multiple enterogenous cysts without evidence of malignancy. Ki-67 (MIB-1) proliferative indices were less than 1% in all except one specimen, wherein it was 4%; immunohistochemistry demonstrated rare p53 protein overexpression.INTERVENTION:During the last 2 years, four subtotal resections of spinal enterogenous cysts have been performed for progressive paraplegia, pain, paresthesia, and bladder dysfunction. Considering the multiple recurrences and progressive neurological deficits, craniospinal radiation therapy was given.CONCLUSION:To our knowledge, this is the first report of widespread craniospinal dissemination associated with the incomplete resection of an enterogenous cyst. Although a rare complication, it emphasizes the advantages of early, aggressive surgery.

摘要:

OBJECTIVE:Angiosarcoma is a rare neoplasm that uncommonly involves the cranium. We report the second case in the literature of a primary right spheno-orbital malignant angiosarcoma.CLINICAL PRESENTATION:This 43-year-old man experienced a 3-month history of rapid growing temporal mass. The results of his neurological examination were normal. Neuroimaging revealed an intensively enhanced right spheno-orbital lesion, with destruction of the greater wing of the sphenoid bone and extension into the orbit, the infratemporal fossa, and the temporal fossa with infiltration of the dura mater but without parenchymal abnormality.INTERVENTION:The tumor was first biopsied and then totally removed, with exenteration of the right eye. The histological features were typical of angiosarcoma with immunohistochemical evidence of Factor VIII-related antigen produced by tumor cells. Neither radiotherapy nor chemotherapy was performed. The patient remained well during 16 months of follow-up, without evidence of recurrence on magnetic resonance images.CONCLUSION:We emphasize the benefit of wide surgical resection without systematic complementary treatment (radiotherapy and/or chemotherapy) in a case of primary angiosarcoma of the cranium. The literature is reviewed.
