Transformation of IDH-wildtype glioblastoma to gliosarcoma with features of osteosarcoma.

Gliosarcoma (GS) is a rare variant of IDH-wildtype glioblastoma. It is classified as grade 4 in the latest WHO CNS classification of both glial and mesenchymal components. Gliosarcoma may arise de novo or secondary from glioblastoma. It occurs in up to 2% of patients diagnosed with glioblastoma. We present a case report of a 51-year-old patient who was initially diagnosed with glioblastoma multiforme, which transformed into secondary gliosarcoma with an osteosarcoma component 16 months after the initial diagnosis. We believe that increasing reporting of secondary gliosarcoma (sGS) will be helpful in understanding, diagnosing and providing more effective treatment for this cancer.

Surgical management of spontaneous intracranial hypotension syndrome: a literature review.

INTRODUCTION: Spontaneous intracranial hypotension (SIH) is a highly disabling but often misdiagnosed disorder. The optimal management options for patients with SIH remain uncertain. The aim of this study was to review studies reporting the management of SIH with a special emphasis on the surgical treatment of SIH including clinical trials, case series and case reports related to the issue of various neurosurgical procedures performed for SIH treatment. OBJECTIVE: The clinical outcomes of patients diagnosed with SIH treated with either only surgery or with surgery as the primary method of treatment were analysed. MATERIAL AND METHODS: The PubMed, Scopus and Google Scholar databases were searched according to the established criteria. RESULTS: The literature search revealed seven clinical trials, five case series and eight case reports regarding surgical treatment of patients diagnosed with SIH. Manuscripts reporting at least five individuals treated surgically for SIH were considered as case series. In most published articles, surgery provided clinical benefit, resulting in a success rate of 82.6-100% for complete relief of SIH symptoms. CONCLUSIONS: Our literature review has revealed that SIH can be diagnosed reliably by MRI and cisternography. The identification of the location of SIH is mandatory for its successful surgical treatment. The clinical outcome is related to the location of SIH in the spinal canal. Most often, cerebrospinal fluid leakage occurs in the thoracic region. Surgical treatment is very effective and the obtained treatment results are complete and permanent. of the location of SIH is mandatory for its successful surgical treatment.

Surgical treatment of spontaneous intracranial hypotension syndrome secondary to the cervical cerebrospinal leak - a case report.

Spontaneous Intracranial Hypotension (SIH) is formed as a result of the leakage of cerebrospinal fluid (CSF) into the extradural space. The most common symptom caused by SIH is headache associated with changes in body position. Imaging, especially magnetic resonance imaging (MRI) of the head and spine with contrast, is the most important examination method in the diagnosis of SIH. In the case of no improvement after symptomatic treatment, surgery is very effective, especially in the case of finding the site of CSF leakage within the spinal canal. A CASE REPORT: We present a case of a 28-year-old patient with 2- month history of severe increasing headaches. The patient denied any head injuries, nasal CSF leakage or lumbar puncture in the past. The neurological examination showed no abnormalities. MRI of the head showed typical features of the intracranial hypotension syndrome. MRI of the cervical spine revealed potential sites for leakage of the cerebrospinal fluid at the C1-C2 level. The patient was qualified for surgical treatment - dural plastic surgery in the cervical section. After treatment the symptoms of intracranial hypotension resolved, and subsequent control MRI examinations showed regression of typical changes of the spontaneous intracranial hypotension. CONCLUSIONS: The authors would like to take notice that imaging diagnostics due to headaches should include MRI of the head and spine, as it is the most important test in diagnosing SIH. Moreover, surgical treatment is a quick and very effective method of treatment.
