A rare case of intramedullary cervical cavernoma with complete neuroradiological examination is described. The Authors debate about clinical course, radiological examination and surgical indications.
The surgical approach to the lesions of the craniocervical junction raises important problems about the choice of the access. The authors debate the advantages and the disadvantages of the principal approaches, presenting their clinical experience of 8 operated patients and discerning between intradural approaches and extradural submucosal or transmucosal approaches.
The Authors describe the case of an intraventricular subependymoma presenting as subarachnoid hemorrhage in a 42-year-old woman. The preoperative and postoperative CT-scans and Magnetic Resonance Images of this rare benign neoplasm are presented. The pathology, the clinical findings and the prognosis of this tumour are discussed.
A case of 61-year-old man with a 2-year history of progressive difficulty in swallowing solid foods is presented. CT-scan and barium swallow test demonstrated an anterior osteophyte at C6. Resection of the osteophyte resolved the dysphagia. The rarity in the neurosurgical literature, the pathogenesis and the management of this condition are discussed.
The authors have reported data on a retrospective study, carried out in order to evaluate the short- and the long-term follow-up results of transsphenoidal microsurgery for prolactin-secreting pituitary adenomas; and to point out the indications for an eventual additional bromocriptine treatment. Prior to surgery, the patients were tested according to the study protocol. Patients were grouped differently according to their adenoma size. We found a good correlation between adenoma size and hormonal values. The surgical treatment led to an immediate endocrine cure in 47 patients (48.9%), with the majority occurring in microprolactinomas. Post-operatively, the cure rate was maintained in 45 patients. The Authors deem the transphenoidal microsurgery the therapy of first choice for microadenoma and mesoadenoma treatment, especially whenever there is bromocriptine intolerance. On the contrary, in invasive macroadenomas, bromocriptine is a necessary additional therapy both to shrink large tumors sufficiently for subsequent transsphenoidal approach and in incompletely removed tumors or persistent hyperprolactinemia.
Aspergillus species are second only to Candidosis as the most common cause of fungal infections of the central nervous system in immunocompromised patients. Very rare is the sole abscessual cerebral localization in nonimmunocompromised patients. Successful treatment of Aspergillus brain abscess has been reported only few times. A case of Aspergillus "primitive" brain abscess treated by surgical therapy associated with local and general mirated antifungal therapy is described. The long-term survival with complete clinical and radiological recovery is reported.
