Spontaneous acute bleeding within subdural effusion from dural metastasis of gastric cancer: A case report.

Dural metastases are uncommon findings and at diagnosis normally appear in disseminated stages of malignant tumors. Usually clinically silent, these could become symptomatic due to mass effect or after developing subdural collections. We present the case of a young woman recently operated from gastric cancer who presented consciousness deterioration and hemiparesis caused by subdural collection. During examination, the patient drastically worsens his neurological status due to an acute subdural bleeding within the subdural collection, which after pathological analysis was diagnosed of dural metastasis of gastric cancer. In malignancies associated with subdural collections it is important to suspect the coexistence of dural metastases and performing a contrast enhanced CT scan or Magnetic Resonance Imaging (MRI) may help in the diagnosis. If surgery is indicated, it is mandatory to evacuate the tumor and involved dura which causes the accumulation of fluid and to coagulate the external tumor membrane to avoid re-bleeding.

Clinical Practice in Spine Surgery: An International Survey.

BACKGROUND: The availability of diverse and sophisticated surgical options to treat spine conditions is compounded by the scarcity of high-level evidence to guide decision-making. Although studies on discrete treatments are frequently published, little information is available regarding real-world surgical practice. We intended to survey spine surgeons to assess clinical management of common spine diagnosis in day-to-day settings. METHODS: An online survey was distributed among neurosurgeons and orthopaedic surgeons worldwide. The obtained assessment of common surgical practice is contextualized in a review of the best available evidence. RESULTS: The survey was answered by more than 310 members of several European, Australasian, and South African professional societies. The submitted responses translate a surgical practice generally grounded on evidence, favoring well-tried techniques, providing comprehensive treatment for the most severe diagnoses. Such practice comes mostly from neurosurgeons focused on spine surgery, practicing in teaching hospitals. CONCLUSION: We believe that the pragmatic, day-to-day approach to spine conditions captured in the present survey offers an informative insight to involved surgeons.

Glioblastoma multiforme metastases to the masticator muscles and the scalp.

Glioblastoma multiforme (GBM) is the most common malignant primary brain tumor. Metastases outside the nervous system are a rare phenomenon. We present a pictographically striking case of GBM with metastases in the masticatory muscles of the infratemporal fossa and the scalp, in the context of a dense intracranial dissemination. Extracranial metastases of GBM have been reported anecdotally, while, to our knowledge, masticatory muscle metastases have been previously reported in only one case.

Anaplastic ependymoma with holocordal and intracranial meningeal carcinomatosis and holospinal bone metastases.

BACKGROUND AND IMPORTANCE: Ependymomas are the most frequent intramedullary neoplasms in adult patients. Anaplastic histology, extramedullary location, meningeal dissemination at initial diagnosis, and extraneural metastases are rare findings. We describe a case of extramedullary anaplastic ependymoma that presented with holocordal and intracranial leptomeningeal carcinomatosis and bone metastases in all the vertebral bodies and the sternum. Such an aggressive dissemination at initial diagnosis has not been previously reported. CLINICAL PRESENTATION: A 36-year-old woman presented with headache, multiple cranial nerve palsies, visual hallucinations, confusion, hemiparesis, hemihipoestesia, episodes of disconnection, and toxic syndrome. Magnetic resonance imaging and positron emission tomography scan revealed leptomeningeal carcinomatosis in the brainstem, the cerebellum, and along the whole spinal cord. Various nodular, intradural extramedullary lesions were present at multiple dorsal and lumbar levels. Metastatic bone disease affected all the vertebral bodies and various extraspinal bones. An intradural and bone biopsy was performed at L4, providing the diagnosis of anaplastic ependymoma (World Health Organization grade III) with focal neuronal differentiation. Despite chemotherapy, the patient's symptoms quickly progressed, and she died 7 weeks after diagnosis. CONCLUSION: To our knowledge, there are no previous descriptions of ependymomas with this extensive leptomeningeal, spinal, intracranial, and extraneural dissemination at clinical onset. Bone metastases in spinal ependymoma have not been previously reported.
