    Intradural solitary fibrous tumor of the lumbar spine: A distinctive case report
    (Hindawi, 2015) Başaran, Recep; Kaksi, Mustafa; Onoz, Mustafa; Balkuv, Ece; Sav, Aydın
    Background. Solitary fibrous tumors are ubiquitous mesenchymal neoplasms of putative fibroblastic origin. They were originally described in the pleura but subsequently have been reported in many extraserosal sites. Solitary fibrous tumors may also occur in the meninges, central nervous system parenchyma, and spinal cord. Case. A 67-year-old male patient with progressive lower extremity weakness, urinary urgency, and sexual dysfunction has been admitted to our hospital. On his lumbar MRI, we detected an intradural lesion posterior to the L3 vertebral corpus. We resected the lesion by L3 total laminectomy. Immunohistological findings revealed strong and diffuse immunopositivity with vimentin, CD34, and bcl-2. Ki-67 proliferation index was 5-8%. We did not detect any recurrence 12 months after his operation. Conclusion. SFT is mostly seen in young and middle-aged patients and should be considered among differential diagnosis in cases suffering from pain, hypoesthesia, and urinary dysfunction. Gross total resection should be primary treatment. Tumors that have high Ki-67 labeling should be followed up for potential recurrences.

    Remote cerebral and cerebellar hemorrhage after spinal surgery: A case report and literature review
    (Ege University Press, 2015) Kakşi, Mustafa; Başaran, Recep; Bölükbaşı, Fatih Han; Balkuv, Ece; Balak, Naci
    Introduction: Remote cerebral or cerebellar hemorrhage is a term used to describe hemorrhage that occurs secondary to different surgical procedures in various areas of body. Intracranial hemorrhages that occur after spinal surgeries are extremely rare. In this article, we aimed to present our experience on remote cerebellar and accompanying cerebral hemorrhage. Case: We present a 73 years old male patient complaining from back pain, bilateral radicular pain and neurological claudication. There were spinal stenosis and disc herniations on levels of L4-5, L5-S1 on MRI. We performed a posterior stabilization, surgery for spinal stenosis and disc herniation that lead to dural defect. We repaired dura and formed a fibrin barrier. Postoperatively, the patient developed a hemiparesis (3/5) on his right side. On CT scan, left parietal and right cerebellar intraparenchymal hemorrhage has been detected. We performed a total evacuation of the hematoma. Conclusion: It should be remembered that during or following spinal surgeries remote infratentorial and accompanying supratentorial hemorrhages can occur due to cerebrospinal fluid leakages, possibly in elderly patients. Early and definite diagnosis is the most precious step for treatment.
