Occlusion of the carotid artery as presenting symptom of acute promyelocytic leukemia.

In a 44-year-old female acute promyelocytic leukemia (APL) presented with abrupt onset of right hemiplegia and aphasia due to occlusion of the left carotid artery at bifurcatio. There was laboratory evidence of disseminated intravascular coagulation (DIC). Thrombotic complications are unusual in APL, even in cases with evidence of DIC. This report aims at underlying the important implication of a correct timely diagnosis in young patients presenting with stroke.

[Comparison of the results obtained using 99mTc HM-PAO tomoscintigraphy and computer tomography in ischemic lesions of the brain].

Fifty patients suffering from cerebral ischemic attacks, transient or not, were studied with both 99mTc HM-PAO single photon emission computed tomography (SPECT) and computed tomography (CT). In 31 patients both SPECT and CT showed pathologic areas, the max diameters of which were measured on CT images and SPECT orbitomeatal reconstructed sections, and then compared. We observed that: only SPECT images are positive for pathologic conditions in transient ischemic attacks and in the very early phases of infarctions; in recent infarctions (less than 15 days earlier) both SPECT and CT scans are positive but SPECT lesion areas are greater than CT ones; pathologic areas, with clear-cut outlines, having the same dimensions on both CT and SPECT images, are supposed to result from old static infarctions. A persistent perilesional hypoactive area on SPECT images means, in our opinion, a hypoperfusional area liable to new vascular troubles; in which case, medical/surgical therapy seems necessary.

Isolated aspergillosis of the sphenoid sinus. Case report.

The Authors report a rare case of isolated sphenoid sinus aspergillosis in a 69-year-old man. The patient had a complete recovery. The preoperative CT-scans and the preoperative and postoperative MRI are shown. The incidence, the pathology, the various clinical presentations, the prognosis and the management of this disease are debated.

Solid supratentorial haemangioblastoma. Case report.

A rare case of solid supratentorial haemangioblastoma presenting in a 67-year-old female with psyco-motory lowering, dysphasia and mild haemiparesis is reported and the pertinent literature is reviewed. The distinction between angioblastic meningioma and haemangioblastoma with the non specific radiological findings of this supratentorial uncommon tumour in are also debated.

Associated cervical schwannoma and dorsal meningioma. Case report and review of the literature.

The association between spinal meningiomas and neurinomas without clinical signs of neurofibromatosis is very rare with only four cases reported in literature. A case of 70-year-old woman with a history of progressive paraparesis is presented. A cervico-dorsal magnetic resonance with contrast showed two tumors with different enhancement. The patient had examination negative for neurofibromatosis. At histological examination cervical schwannoma and a dorsal meningioma were found. The Authors debate the rarity of this association, the possible pathogenesis and the MR findings.

Surgical approaches to the clivus and upper cervical spine.

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.

Intraventricular subependymoma presenting as subarachnoid hemorrhage. Case report.

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.

Dysphagia due to anterior cervical osteophyte. Case report.

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.

Treatment and long-term follow-up results of prolactin secreting pituitary adenomas.

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.

Drainage of Aspergillus "primitive" brain abscess with long-term survival. Case report.

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.
