This rare birth defect occurs when the neural tube, in which the brain and spinal cord form, fails to close completely during fetal development. Skin or a thin membrane covers the sac outside the skull. Encephaloceles can occur in the base of the skull, at the top or back of the skull or between the forehead and nose. Conditions associated with encephalocele include hydrocephalus, developmental delays, microcephaly (an abnormally small head), paralysis and seizures. Each year, about one out of every 10, 000 infants born in the United States will have encephalocele, according to the Centers for Disease Control and Prevention. Fibrous Dysplasia Fibrous dysplasia is a rare bone disorder in which scar-like fibrous tissue develops instead of normal bone. As the bone grows, the fibrous tissue gradually expands, weakening the bone. Fibrous dysplasia usually develops in the skull base and facial bones, thighbone, shinbone, ribs, upper arm bone or pelvis. Fibrous dysplasia can lead to pain and broken or deformed bones.

When breast or kidney cancer spreads to the brain, it usually causes a single tumor (also referred to as a "lesion" or "focus"). When lung, melanoma or colon cancer spreads to the brain, it often causes multiple tumors (foci). This occurs in about 80 percent of metastatic brain tumors. Metastatic brain tumors are more common in middle-aged and elderly adults than in younger individuals. In most cases, patients know they have cancer in the primary location and the brain metastasis is often found during a routine computerized tomography (CT) scan or magnetic resonance imaging (MRI) study. In less than 10 percent of patients, the metastatic brain tumors are diagnosed before the primary cancer and are found as a result of neurological symptoms. When this occurs, further tests are done to determine where the cancer originated. Often metastatic brain tumors are found before they cause symptoms. In other cases, patients may experience symptoms that prompt investigation: Headaches Loss of coordination (being unbalanced or weak on one side of the body) Behavioral or cognitive changes Specific symptoms depend on the location of the tumor in the brain.

Individuals affected by NGGCTs have an average of 5 year survival rate. Signs and Symptoms [ edit | edit source] Germ cell tumors typically vary in symptoms depending on their type and location Ovarian: Ovarian germ cell tumors are hard to detect and typically grows to a relatively large size before symptoms can be seen. Swelling in the abdomen is a possible sign in the later stages of this cancer. Testicular: Testicular tumors can be detected during the early stages due to the fact that they are noticeable in the scrotum and can cause pain. [1] Mediastinum Tumors: Mediastinum tumors are located within the cavity that contains the heart, trachea, connective tissues, thymus, and large blood vessels. These tumors usually cause chest pain, coughing, fever, and breathing problems. Presacral Tumors: Presacral tumors are located in areas above or on the dorsal side of the sacral bone of the hip. This type of germ cell tumor usually appears as a mass in the lower abdomen of a child. It can cause difficulty in passing urine or enabling bowel movement.
These may include headaches, seizures, problem with vision, vomiting, and mental changes. [4] Not all brain tumors are alike, even if they arise from the same type of brain tissue. Tumors are assigned a grade depending on how the cells in the tumor appear microscopically. The grade also provides insight as to the cell's growth rate. The following grades are: Grade I: The tissue is benign. The cells look nearly like normal brain cells, and they grow slowly. Grade II: The tissue is malignant. The cells look less like normal cells than do the cells in a grade I tumor. Grade III: The malignant tissue has cells that look very different in appearance from normal cells. The abnormal cells are actively growing and have a distinctly abnormal appearance (anaplastic). Grade IV: The malignant tissue has cells that look the most abnormal and tend to grow quickly. [5] Tests for brain cancer involve a history, physical exam, and usually a CT or MRI brain scan; sometimes a brain tissue biopsy takes place as well.
Eighty percent of patients have involvement of 2 or more glands, and pituitary tumors occur in 54% to 80% of patients with MEN I. MRI most readily determines the presence of a pituitary tumor, although it may also be established by CT (computer tomography) scan. Many patients experience visual loss. Headaches occur in about 20%. Treatment [ edit | edit source] Treatment depends upon the type of tumor and if it extends into the brain around the pituitary. Hormone-secreting tumors may be treated with surgery or radiation therapy. Drug therapy with bromocriptine has been used with success in patients with prolactin-secreting tumors.
Let Us Help You Find a Doctor At Houston Methodist Hospital we offer patients world-class, personalized treatment of brain and pituitary tumors. Our approach to healing takes advantage of recent advances in medical science, such as using a variety of new technologies to study each tumor and optimizing treatment for each individual based on the genetic profile of the patient and/or their tumor. We are committed to creating a compassionate environment for our patients. Many of our doctors are active researchers and educators, tackling big issues in brain, spine and pituitary cancers, and training the next generation of specialists in these areas. In classifying brain tumors, the first distinction is whether the tumor originated in the brain or started in another area of the body and spread to the brain. Primary brain tumors, such as glioblastomas and anaplastic astrocytomas, are among the types of tumor that originate in the brain. Secondary, or metastatic, brain tumors originate in other parts of the body and spread to the brain.
They usually develop in the legs, pelvic area, head and neck. While most hemangiopericytomas are found in soft tissues, some may occur in the nasal cavity and paranasal sinuses. These tumors may be benign — if they are malignant they can spread to the bone, lungs or liver. Meningioma Meningioma is the most common primary brain tumor, accounting for about 33 percent of all primary brain tumors. Meningiomas originate in the meninges, the outer three layers of tissue that cover and protect the brain just under the skull. About 85 percent of meningiomas are benign, slow-growing tumors. Some meningiomas have been found growing in the skull base. Metastatic Brain Tumor Metastatic brain tumors, also called secondary brain tumors, are malignant tumors that originate as cancer elsewhere in the body and then metastasize (spread) to the brain. Metastatic brain tumors are the most common type of brain tumor, occurring about four times more often than primary brain tumors. They can grow rapidly, crowding or destroying nearby brain tissue.

While these tumors grow slowly, they may eventually cause the bone to fracture or grow too much, creating pressure on the brain. In rare cases, chondromas may change into a cancerous condition called chondrosarcomas. Chondrosarcoma Chondrosarcoma is a malignant bone cancer that mainly affects cartilage. The second most common type of bone cancer, chondrosarcoma usually develops in patients between the age of 50 and 70. The tumor can begin in cells in the thighbone, arm, pelvis, knee and spine. It may also start in the skull base. Some of these cancers can be aggressive. Chordoma Chordomas are benign, slow-growing tumors usually found in the base of the skull. They may also appear in the lower spine. Less than 1 percent of all primary brain tumors are diagnosed as chordomas. This type of tumor can invade adjacent bone and put pressure on nearby nerve tissue. Choroid Plexus Tumor Choroid plexus tumors are rare tumors that are found in the choroid plexus—the part of the brain within the ventricles that produces cerebrospinal fluid.
