Atypical Presentation of Orbital Pseudotumor with Visual Loss as an Initial Manifestation
Recai Turkoglu,Naci Balak 대한신경과학회 2011 Journal of Clinical Neurology Vol.7 No.1
Background:An orbital pseudotumor typically presents with periorbital pain, cranial nerve palsies and proptosis. Although visual deterioration is not unexpected in this pathology, its presentation solely with visual loss is unusual. Case Report:In this short report, we summarize a case of orbital pseudotumor which presented solely with a decrease in visual acuity, and discuss the clinical and radiological findings. This part can be moved to the conclusion part. However, It is also good in this location. Conclusions:In the early clinical period, an orbital pseudotumor may manifest itself solely by visual loss. It should therefore be included in the differential diagnosis of visual pathologies-even in the absence of orbital pain and symptoms related to ocular movements.

Objective : It is well known that changes in cerebral hemodynamics occur after traumatic brain injury (TBI). Osmo-regulation in the brain is important for maintaining a constant milieu in the central nervous system. Nevertheless, to our knowledge, early osmolarity changes after minor head injury have not been studied until now. Methods : In this study, serum osmolarity was measured in 99 patients with minor head trauma. As a control group, blood samples were drawn from 99 patients who had a minor trauma in an extremity. Serum osmolarity was estimated using a fully automatic biochemical autoanalyzer within the first 3 hours after the trauma. Results : The mean serum osmolarity levels were $286.08{\pm}10.1\;mOsm/L$ in the study group and $290.94{\pm}5.65\;mOsm/L$ in the control group (p<0.001). However, after age adjustment between the study and control groups, this statistical significance was found to be valid only for patients over 30 years of age. Conclusion : It was noted that serum osmolarity levels decrease in the first 3 hours following minor head trauma in patients over 30 years of age. Further studies into this area could provide guidance for the management/treatment of elderly patients.
