The article presents a case study of a 45-year-old female presented with complaint of severe headache that was localized to the left retro-orbital region. Neurological examination found left oculomotor palsy with an inability to rotate the eye inwards. Details are presented about xanthogranulomas, also known as cholesterol granulomas, of the stellar region.

Failed Back Surgery Syndrome (FBSS) refers to a subset of patients who have new or persistent pain after spinal surgery for back or leg pain. Epidural fibrosis (EF) is a common cause of FBSS. Many agents aiming to prevent EF have been tested. However, hemostatic agents are readily available at hospitals, easy to reach and frequently used. For these reasons, oxidized regenerated cellulose, polysaccharide hemostat, hemostatic thrombin-gelatin matrix and chitosan linear polymer were evaluated for their effects on epidural fibrosis on rats after laminectomy. 40 Sprague–Dawley rats were randomly divided into 5 equal groups including the control group where only the laminectomy was performed. The other 4 groups received hemostatic agents after laminectomy. The rats were euthanized 45 days later and were assessed by a blinded observer to grade the fibrosis level. The study revealed that oxidized regenerated cellulose, polysaccharide hemostat and hemostatic thrombin-gelatin matrix lowered the epidural fibrosis grade which was statistically significant (p < 0.001). Although chitosan linear polymer created fibrosis similar to the control group it was not proven to be statistically significant (p = 0.8999). However, when compared with other hemostatic agents it resulted in a higher fibrosis grade (p < 0.001). The results obtained from this experimental study revealed that Pahacel, Sealfoam and Surgiflo, were effective in reducing epidural fibrosis after laminectomy in rats. [ABSTRACT FROM AUTHOR]

The article presents a case study of 46-year-old patient diagnosed with calcified extraventricular neurocytomas (EVNs) through radiological-pathological correlation. Topics discussed include treating patient's disease through subtotal surgical excision and adjuvant therapy, CT and MRI imaging findings of calcified, extraventricular, right frontal mass and radiological diagnosis of meningioma to the patient.

Cerebral hydatidosis accounts for approximately 1–3% of all cases of hydatid disease. In this report, 32-year-old female with epidural multilocular hydatid cysts in the midline posterior parietal region is reported. Most commonly, cerebral hydatid cysts are single lesions and locate in the watershed of the middle cerebral artery. However, cerebral epidural hydatid cysts seem to have a tendency occurring around in the highly vascularized venous sinus. [ABSTRACT FROM AUTHOR]
