The anatomy, pathophysiology nad treatment of the pineal region tumors are presented. The authors stress the role of stereotactic biopsy in the diagnosis and correct management. Based on the literature and their experiences the risk of complications and incorrect diagnosis is discussed.

[The significance of stereotactic biopsy in the diagnosis and treatment of central nervous system lymphomas].

The paper presents seven cases of central nervous system lymphomas diagnosed in Department of Neurosurgery of Military Clinical Hospital in Bydgoszcz. The role of stereotactic biopsy in the management of this entity is underlined. Clinical, radiological and pathological symptoms met in PCNSL (Primary Central Nervous System Lymphoma) are briefly described.

[Pathomorphological evaluation in stereotactic brain tumor biopsy].

The method is described of multistep pathomorphological examination of biopsy material obtained by stereotactic procedures from brain tumours. In the analysis of 260 biopsies the possibility was assessed of intraoperative cytological examinations confronting the results of these examinations with those of final histological and immunohistochemical investigations. Attention is called to the difficulties in the evaluation of material derived from stereotactic biopsies and to the cause of possible diagnostic errors. It is concluded that the combination of the results of cytological examination of smears and histological examination of paraffin slides makes possible establishing of full pathomorphological diagnosis with determination of tumour type and its malignancy degree in 90.7% of cases. On most cases cytological intraoperative examination had the greatest influence on therapeutic management. In the confrontation of these examinations with histological examinations a high proportion of correct cytological examinations was found (76.6%). Owing to the possibility of application of all techniques of morphological diagnosis, stereotactic biopsy is a reliable method in the diagnosis of brain tumours.

[Stereotactic biopsy of polylmorphic tumors and brain tumors invisible in CT image].

The authors present the possibilities of obtaining tissue samples with stereotactic biopsy basing on three examples of intracranial polymorphic and invisible in CT tumours. CT scans of these tumours make a serious problem with proper targeting and tissue sampling from proper sites. Stereotactic serial biopsy directed by CT/MRI fusion is the best way of obtaining tissue material in order to establish correct diagnosis.

[Cerebral blood flow changes after mild head trauma imaging with SPECT HMPAO. Preliminary report].

The authors present 3 cases of mild head trauma diagnosed by CT, EEG and SPECT. The results showed that CT scan was negative in all cases while SPECT was positive. EEG recording showed changes which seemed to agree with the changes of regional cerebral blood flow presented by SPECT. This initial results indicate that SPECT HM-PAO within the first two-three days is more sensitive than CT scan and detects brain perfusion abnormalities.

[Thoracic outlet syndrome: results of surgical treatment].

21 patients with thoracic outlet syndrome (t.o.s.) were operated on in the Department of Neurosurgery of MMA in Lódź between 1982-1991. Early and long-term results of treatment were analyzed in the group of 13 cases. In early postoperative period 5 patients were free of pain and neurologic or vascular disturbances in the upper limb. In other 6 cases pain disappeared partially and mild neurological or vascular syndromes persisted. Altogether satisfactory results of treatment were obtained in 8 patients (85%). There was some improvement in 2 patients but pain and neurological or vascular disorders were still significant after surgery. Long-term results were assessed at least 1 year after operative treatment. Recurrent pain with or without mild neurological (vascular) syndromes appeared in 6 patients (46%). Recurrent t.o.s. occurred mainly in cases of young women with low position of shoulder girdle and poorly developed musculature of this region. Only 2 patients still remained free of preoperative syndromes. Altogether only 8 patients (61%) had acceptable results of surgical treatment at long-term follow-up. The remaining 5 patients (39%) had unsatisfactory long-term results.

[Epidemiology, diagnosis and prognosis in the clinical syndrome of brain concussion].

The paper is a continuation of the preliminary communication in Neurologia i Neurochirurgia Polska No 3/1995. The study in 1993-1995 included a group of 50 patients who had clinical symptom complex of brain concussion. After preliminary neurological assessment within 3 days in all cases brain CT and cerebral perfusion determination (SPECT M-PAO) were obtained. Focal reduction of blood flow was demonstrated in 47 cases, mostly in the temporal area (78%). In 30 cases EEG was done finding in 18 disturbances of cerebral electric activity. In 9 cases neuropsychological examination was done. After 3 months control study of cerebral perfusion was done in 28 cases and in 27 flow changes were found to persist. Another follow-up examination in 6 cases after a year demonstrated in all of them focal disturbances of cerebral blood flow associated with symptoms of postconcussion syndrome.

[Complications after surgery of the anterior cervical spine].

Every year several thousands of operations on the cervical spine from anterior approach are performed in the world for decompression of spinal cord and nerve roots. It is estimated that in 0.2 to 12% of the operations serious intraoperative and postoperative complications occur. Such cases have been reported in the world literature but in scant numbers. The authors discuss early and late complications after operations on the cervical spine connected with the surgical method.
