  • tumor

  • Skull base surgery is a new cross edge discipline which has been formed in recent years and primary skull base tumor has less incidence in clinical relatively. (spandidos-publications.com)
  • The tumor will often affect multiple sites within the upper aerodigestive tract, frequently showing extension into the orbit (25%) or through the cribriform plate (11%) of the ethmoid sinus into the skull base. (wikipedia.org)
  • It is important to understand that, while tissues behind (or deeper than) the tumor receive almost no radiation from proton therapy, the tissues in front of (shallower than) the tumor receive radiation dosage based on the SOBP. (wikipedia.org)
  • However, this term is to be discouraged, as it implies a neoplasm or tumor, which it is not. (wikipedia.org)
  • EMECL is staged in the same manner as other non-small cell lung carcinomas, based on the TNM (Tumor-Node-Metastasis) staging system. (wikipedia.org)
  • Appearance
  • Radiographic Appearance of Skull Base Neoplasms. (mhmedical.com)
  • Gardner syndrome can be identified based on oral findings, including multiple impacted and supernumerary teeth, multiple jaw osteomas which give a "cotton-wool" appearance to the jaws, as well as multiple odontomas, congenital hypertrophy of the retinal pigment epithelium (CHRPE), in addition to multiple adenomatous polyps of the colon.

  • Even in emergency situations, when a head injury is minor as determined by a physician's evaluation and based on established guidelines, CT of the head should be avoided for adults and delayed pending clinical observation in the emergency department for children. (wikipedia.org)
  • Clinical trials have shown the efficacy and safety of using CT of the head in emergency settings only when indicated, which would be at the indication of evidence-based guidelines following the physical examination and a review of the patient's history. (wikipedia.org)
  • radiation
  • In these cases, untreated survival usually amounts to only a few months, and survival with current radiation and chemotherapy treatments may extend that time from around a year to a year and a half, possibly two or more, depending on the patient's condition, immune function, treatments used, and the specific type of malignant brain neoplasm. (wikipedia.org)
  • system
  • Direct invasion or compression from continuous tissues relates to the proximity of the nervous system to other structures, such as the brachial plexus, lumbosacral plexus, vertebral neuroforamina, base of skull, cranium, and pelvic bones. (wikipedia.org)
