Several theories have been suggested to explain its occurrence. The main symptoms are painful abdominal distension and vomiting, abdominal distension on examination, as abdominal ultrasound and computed tomography confirm its diagnosis. The treatment involves drainage associated with drain relocation and resection of the pseudocyst’s wall. We report two patients diagnosed with this condition who underwent surgical treatment. The first patient had an unremarkable 12-month follow-up, while the second died on the seventh postoperative day due to intravascular disseminated coagulation. In these patients, the cause has not been identified;however, an infection cannot be ruled out.展开更多

The metastasis of malignant meningiomas to distant extracranial sites are well known. However, dissemination of the tumours in the cerebrospinal fluid （CSF） is rare and few cases have been reported. We present a case of histologically proven malignant meningioma with CSF dissemination at the remote intracranial area and into the spinal canal detected with maqnetic resonance imaging.展开更多

A review of 29 spinal CCM previously reported was done. Objective: To focus on clinical and biological behaviour of CCM. Summary of background data: CCM is a rare subtype characterrized by its inordinately aggressive clinical course despite its benign appearance. The tumour shows proclivity for the cerebellopontine angle and cauda equine region. Recurrence and metastasis have been commonly reported. Method: A 26 year-old man presented with low back pain related to a lytic lesion of the sacrum. He had a history of an intradural extramedullary meningioma of the cervical spine removed when he was 9 year-old. CT scan revealed a sacral osteolytic lesion with anterior and lateral extension. Open biopsy revealed a clear cell meningioma. That was the same pattern of the tumour removed 17 years before. Results: Our patient was managed conservatively by palliative radiation therapy. At 2 years follow-up, he experienced improvement of pain and walking. Conclusion: CCM is an aggressive tumour with a high risk of metastases through cerebrospinal fluid. A follow up with spinal MRI should be performed.展开更多

However, the actual changes of cerebrospinal fluid （CSF） pressure and its relation with spinal cord ischemia have been poorly understood. We performed CSF pressure measurements and provisional CSF withdrawal after thoracic endovascular aortic repair, and compared the changes of CSF pressure in high risk patients and in patients with new onset paraplegia and paraparesis.展开更多
