Clinical, Instrumental and Immunological Follow-Up of Patients with Brain Tumors

Dynamic assessment of 66 patients with different brain tumours was carried out. The clinical, immunological and instrumental (electrophysiological and neuroimaging) follow-up included three groups of cases with stable clinical course, tumour progression and recurrence. Our results confirm that the changes in the functional and immune status of the patients with cerebral neoplasms as well as the alterations in the cerebral function and structure reflect the tumour development and the corresponding therapeutic behaviour. Monitoring of patients status and tumour growth provides opportunity for better disease control and prognosis

INVESTIGATION OF VISUAL ASSESSMENT OF ALTERNATING LUMINOUS AREAS IN NEUROOPHTHALMOLOGICAL DIAGNOSIS OF PATIENTS WITH INTRA - AND PARASELLAR TUMORS

The method for investigation of visual assessment of alternating luminous areas (VAALA) enables to establish visual disorders in different diffusive and local brain lesions including brain tumours. In this study the applicability of VAALA in the complex neuroophtalmological investigations in patients with intra- and pa nisei I ar tumours was analyzed. VAALA, peripheral vision, and visual acuity were assessed in 9 patients with extrasellar tumours and in 5 patients with intrasellar ones. VAALA showed changes in all the patients without any significant difference between both patients' groups. Routine neuroophthalmological examination even in patients with extrasellar tumours indicated some typical abnormalities in a part of the cases only while in single cases of intrasellar tumours only initial changes could be detected. Perimetria and especially visual acuity and VEP possessed a lower diagnostic value in perichiasmatic lesions than contemporary psychophysical tests, VAALA inclusive. The high sensitivity of VAALA concerning the visual disturbances in pathological processes in these areas enables its integration into the complex neuroophthalmological examination

Transient monocular visual loss due to multiple CNS vascular pathology: report of two cases

BACKGROUND: The frequency of the transient monocular visual loss (TMVL), lasting minutes or longer, varies from a single to many episodes, which are usually followed by complete recovery of vision. TMVL is related most commonly o occlusive carotid disease. The therapy of patients with TMCL is divided into surgical and medical.CASE1: A55-year-old female was admitted to the clinic, with 4 months history of TMVL of the right eye, lasting 2-3 minutes, followed by complete recovery. Neuro-ophthalmological examination was normal. Neuro imaging investigations revealed proximal part right internal carotid artery (ICA) stenosis of 70%, left ICA stenosis of 40%, King-King in the middle segment of ICA, causing stenosis of 14%, and incidental aneurysms of the intracranial part of right ICA andin M2 segment of right middle cerebral artery.CASE2: A 74-year-old female was admitted to the clinic, with 1 year history of TMVL of the right eye, lasting 4-5 minutes, followed by complete recovery. Neuro-ophthalmological examination was normal. Duplex scaning showed hemodynamically significant stenosis of the right ICA, with King-Kingintheleft. MRI reveale diffuse vascular pathology.CONCLUSION: These cases demonstrated a co-occurrence of hemodynamically significant carotid artery occlusion with multiple or diffuse vascular pathology in patients with TMVL. We suggest that the detailed history, neuro-ophthalmological, and neuroimaging examinations might be useful to determine the correct etiologic diagnosis and discuss the most effective therapeutic strategy in TMVL patients.Scripta Scientifica Medica 2011;43(2):83-8
