You'll be sedated and sleepy while part of your skull is removed in the beginning of the surgery, and also when doctors reattach the skull at the end of the surgery. During the surgery, your anesthesiologist will stop administering the sedative medications and allow you to wake up. If your brain tumor or epileptic focus is close to areas of your brain that control vision, speech or movement, your doctor will conduct brain mapping.
This provides your neurosurgeon with a map of the brain centers that control each of these functions.
Neurosurgeons Perform Region's First Awake Craniotomy - Mind & Body
Your surgeon also can perform brain mapping deeper in your brain during surgery. Your neurosurgeon uses this map to avoid damaging these areas and preserve these functions. Brain mapping, along with 3-D computer images, allows your surgeon to safely remove as much of your brain tumor or epileptic focus as possible and lower the risks of damaging important body functions.
During surgery, your neurosurgeon or a speech-language pathologist may ask you questions or ask you to identify pictures and words on cards or computer that you saw before surgery. Your doctor may ask you to make movements, identify pictures on cards, count numbers or raise a finger.
Your responses help your surgeon identify and avoid the functional areas in your brain. Your medical team also uses detailed 3-D computer images of your brain taken before and during your surgery, including intraoperative MRI and computer-assisted brain surgery, to guide removal of as much of the brain tumor or epilepsy focus as possible. Your anesthesiologist and surgical team carefully monitor and assess your body and brain functions and alerts your surgeon if surgery affects brain function. After surgery, your surgeon may request an MRI to ensure that removal of the tumor or epileptic focus is complete.
You'll probably be in the intensive care unit for a while after surgery and spend about two to three days in the hospital. You generally may return to work and normal activities in six weeks to three months.
You'll have a follow-up appointment with your doctor about three months after surgery. If you had awake brain surgery to manage epilepsy, you generally should see improvements in your seizures after surgery. Some people are seizure-free, while others experience fewer seizures than before the surgery. Occasionally, some people have no change in the frequency of their seizures. If you had awake brain surgery to remove a tumor, your neurosurgeon generally should have been able to remove most of the tumor. You may still need other treatments, such as radiation therapy or chemotherapy, to help destroy remaining parts of the tumor.
Kelley says that an awake craniotomy is just what it sounds like. Local anesthesia in the form of a scalp block with mild intermittent sedation is usually enough to eliminate any feelings of pain. The brain mapping and patient interaction functions associated with the procedure have been shown to offer better outcomes and more functionality preservation than other treatments while allowing for the maximum amount of tumor to be safely removed. Recovery time is also shortened. Kristy Armand Submit comment Tell a friend Tweet.

Information from references 2 through 6.
In studies of children with malignant tumors, the median delay in diagnosis was nine weeks for brain tumors, three weeks for leukemia, and In this review, we present common and less common early presenting signs and symptoms of childhood cancer, with an emphasis on red flag symptoms that should prompt evaluation. Cancer diagnosis in children is often delayed because the presenting symptoms tend to be nonspecific and resemble those of benign conditions.
In children who exhibit red flag symptoms for malignancy, a complete history, including personal and family history, is fundamental. Preliminary symptoms may have started abruptly e. They may also be constitutional and nonspecific e. A focused physical examination, including funduscopy, should follow. Most red flags e. It is important to interpret the red flag finding in combination with other findings from the history and physical examination, especially if the patient presents repeatedly with the same symptom or if the symptom persists.
The most common nonspecific signs and symptoms associated with an underlying malignancy are listed in Table 2. Leukemia, lymphoma, neuroblastoma, Ewing sarcoma, Wilms tumor, histiocytosis, nasopharyngeal carcinoma. May be associated with pallor, petechiae, weight loss, bone pain, lymphadenopathy, hepatosplenomegaly, or a palpable mass.
Protracted, unexplained anorexia, especially if accompanied by significant weight loss or other suspicious findings recurrent infections, fever, pallor, lymphadenopathy, hepatosplenomegaly. Coexisting fever, night sweats, weight loss, malaise, pallor, hepatosplenomegaly. Hemorrhagic manifestations petechiae, ecchymoses, recurrent epistaxis, bleeding gums.
Persistent and combined with other signs of bone marrow infiltration pallor, fatigue, recurrent infections. Of new onset, persistent, occur in the morning or awaken the child from sleep; without history of migraine; associated with vomiting or neurologic deficits cranial nerve palsies, motor and sensory signs ; occipital location; worse when lying down. Any mass discovered outside the neonatal period has high probability of malignancy, especially when associated with vomiting, abdominal pain, constipation, hematuria, or hypertension.
Persistent and recurring; associated with morning headaches; associated with abdominal mass. Brain tumors, abdominal tumors neuroblastoma, Wilms tumor, lymphoma, hepatoblastoma. Same as the above, and central nervous system tumors. Neuroblastoma, tumors of the spinal cord or pelvis ovarian, soft tissue sarcoma. Symptoms are listed in order of how often they are encountered in malignancies and on their clinical importance i. Tumors are presented in order from most common to least. Information from references 4 through 6 , and 10 through Prolonged fever with no identifiable cause is a common symptom of cancer in children, and is associated mainly with leukemia or lymphoma.
Anorexia is common in many childhood illnesses. The differential diagnosis includes idiopathic thrombocytopenic purpura, clotting factor deficiencies, and platelet dysfunction. In conclusion, any combination of persistent or unexplained fever, recurrent or persistent infection, pallor, malaise, hemorrhagic manifestations, hepatosplenomegaly, or lymphadenopathy should be evaluated with complete blood count and blood smear. Localized or generalized lymphadenopathy is a common complaint in children.
Most cases of lymphadenopathy are benign and related to infections or collagen vascular diseases. A neurologic examination and funduscopy should be performed to help distinguish a brain tumor from conditions such as migraine, sinusitis, tension headache, and ocular abnormalities.
Your gateway to responsible information about the brain
Abnormalities of gait ataxia and coordination increase suspicion for brain tumor, especially of the posterior fossa. Any abdominal mass should be treated with a high degree of suspicion. In neonates, abdominal masses are usually of benign genitourinary origin.
The differential diagnosis also includes cysts and benign tumors of the kidneys, ovaries, or soft tissues. Abdominal masses, as well as any degree of hepatosplenomegaly, call for further investigation with ultrasonography, especially if they are associated with anorexia, vomiting, fever, pain, or a child who appears ill. Recent onset constipation that persists and does not respond to conservative treatment should be evaluated for abdominal masses that may cause bowel obstruction or spinal cord lesions that affect sphincters.
Bone pain that occurs at night, awakens the child, and is persistent or intermittent can be a first sign of malignancy. Localized pain associated with swelling or deformity may indicate a bone tumor. Generalized bone pain may indicate leukemia or neuroblastoma. Back pain merits further investigation with CBC, blood smear, C-reactive protein level, and two-view radiography of the spine if the child is younger than four years, if the pain worsens at night, or if there are concurrent symptoms.
Radiation Therapy for Brain Tumors
Hematuria is a frequent finding in urinary tract infections, trauma, or lithiasis. If common causes have been excluded, renal tumor or soft tissue sarcoma should be considered. Urine retention or enuresis of recent origin may result from spinal or pelvic tumors. Every scrotal mass should be investigated, because it may be caused by a soft tissue or germ cell tumor, or even leukemia.
Initial Assessment and Clinical Examination
Rarely, cardiorespiratory symptoms may be associated with malignancy. Nonproductive cough, dyspnea, or orthopnea with no obvious cause that persists for more than two to three weeks and does not respond to treatment, or that is associated with other disturbing findings lymphadenopathy, weight loss, fever, pallor, facial swelling or plethora may result from a mediastinal mass or a pleural effusion caused by lymphoma or leukemia.
Gingival swelling or bleeding may result from gum infiltration in leukemia or histiocytosis. Dermatologic manifestations provide information on bone marrow function through clinical signs such as pallor and bruising or petechiae. Several ocular symptoms warrant immediate attention because malignancy should be excluded before other diagnoses are considered.
Squinting and diplopia are red flags for tumors of the eye and brain. Leukokoria cat's eye reflex is a red flag for retinoblastoma. Proptosis is a red flag for space-occupying lesions of the orbit rhabdomyosarcoma, leukemia, optic glioma, histiocytosis. Aniridia may be associated with Wilms tumor. The most common endocrine symptoms associated with childhood malignancies are described in Table 3. They may be caused by endocranial tumors causing hypopituitarism or by hormone-secreting germ cell tumors. Craniopharyngioma, germinoma, histiocytosis, suprasellar tumors of the pituitary gland.
Craniopharyngioma, germinoma, suprasellar tumors of the pituitary gland or the hypothalamus. Adrenal tumors, central nervous system tumors, human chorionic gonadotropin—secreting germ cell tumors, rhabdomyosarcoma. Information from references 25 , and 30 through Paraneoplastic syndromes and symptoms are more common in adults than in children. Hypertension, erythrocytosis, Cushing syndrome, acquired von Willebrand disease. Bursts of rapid, chaotic eye movements with frequent, involuntary, irregular, jerking muscle movements. Musculoskeletal pains, fever, fatigue, arthritis, weight loss, hepatomegaly, back pain.
