3rd ventricle syndrome

Outlined in the third ventricle between the central brain, the hypothalamus and on both sides of the hypothalamus between the sagittal narrow gap, it through the front room with the hole between the lateral ventricle, so that the rear linked with the fourth ventricle. 3rd ventricle syndrome often caused by tumor, the more performance for the nearby structure of oppression symptoms. Cause pathogenesis by the third ventricle tumors near the oppression can block the circulation of cerebrospinal fluid caused hydrocephalus. causing increased intracranial pressure, and other symptoms. A clinical performance. Intracranial hypertension : the most common sudden headache, vomiting, lethargy, disturbance of consciousness. Headache may take certain positions terminated after repeated attack. 2. Focal symptoms : hypothalamus structure compression symptoms, there is more urine, body temperature and brain increased obesity. Later accompanied sleepiness and sexual hypofunction, impotence, menstrual disorders, muscular sexual precocious child. 3. Long-term symptoms : performance for tinnitus, hearing loss, corneal reflex, balance instability, muscle tension dry limbs fall, Sarah gait. 4. Psychiatric symptoms : patients with memory loss and emotional instability, irritability, or defied the spirit of recession. Differential diagnosis (1) the third ventricle tumors (tumor of third ventricle) swelling Tumor obstruction of cerebrospinal fluid cyclical obstacles, have increased intracranial pressure, common sudden headache, drowsiness, vomiting, disturbance of consciousness, and the rapid mitigation, repeated attack. Postural changes can induce symptoms worsen before prone position at the most obvious. Patients often can not bend down to apologize, not engaged in horticultural activities. Volatile parts of headache, or in the forehead, or the volume of occipital pain, headache or side, or both sides of headache, This can be a headache to take certain positions terminated. Headache duration is short for a few minutes long, a few hours after a fierce attack by the Standing a few months or years without fat. Vomiting often appeared at the height of the headache, or is about to ease the headache occurred, vomiting appeared often presage a headache coming to an end. Drowsiness speaking asleep few days, strong stimulation can awaken. (2) the third ventricle mucocele (colloidcyst of third ventride) The slower development of the disease, often after a few years the evolution of oppression have not yet seen symptoms. Clinical often obstructive room between holes caused obstructive hydrocephalus and the symptoms of increased intracranial pressure. Intracranial hypertension with early symptoms of attack was, the late consecutive features. Patients with sudden headache, vomiting and even coma, the duration generally not long and the short is a few minutes long, a few hours basis. changes in the first place to be lifted, eased up to a few months, after the frequent seizures, duration lengthened. Headache gradually with obesity, weakness, pronunciation incomplete, inadequate sexual function, no visual impairment. No drowsiness, polyuria, clinical and endocrine disorders extremely difficult to identify. Cerebrospinal fluid examination in more than half of cases without any changes, location Case cell count increased protein levels, Mononucleosis usually in the 30 below, in the 200 individual above. Ventricular angiography clearly see the third ventricle graphics defect. (3) chromophobe cell tumor (chromophobe cell tumor) of the disease as the most common pituitary tumors A see, was particularly prevalent in the 31-50-year-old. First symptoms of visual effects and the typical defects of vision, double-temporal hemianopsia. More than 60% of patients with symptoms of headache, the general is not serious, early headache for more traction saddle phrenic tumor caused seizures were, But not because of changes in the first place intensified or disappeared. Endocrine disorder symptoms of sexual dysfunction, male sexuality flu retreat, impotence, female menstrual disorders. Visibility physical stunting dwarfism, mental poor. Because the optic nerve compression and blood circulation obstacles, more than 70% of patients with primary optic atrophy nipple, and the many bilateral begin at the same time. In a few cases there hydrocephalus, increased intracranial pressure, but this is not the symptoms of sexual attack. Skull X-ray film can be seen Sella spherical expand the typical change. (4) intraventricular hematoma (intraventricular hematome) in multiple elderly , and a history of traumatic brain injury patients after the rapid increased intracranial pressure, dark unconscious, soon bilateral pyramidal tract sign, bilateral Mydriasis or narrow, irregular breathing, brain membrane irritation sign Obviously, there autonomic dysfunction. Headache common than brain tumors more intense. (5) sequelae of traumatic brain injury (post-traumatic brain sequel) with the disease - like complex, headache common headache can be located in the whole head was pulsating pain or pain, sometimes displayed stun-like pain. External stimuli such as noise can cause or aggravate headache, and often forgotten headache increase. Most patients were dizziness, insomnia, memory loss and lack of concentration, emotional stability owed. (6) the skull base indentation Disease (basis cranii indentation) of the patients in 20 regular ~ 30 years before onset of symptoms. Occipitocervical performance is usually pain, was radioactive, with local tenderness, limited rotation and had forced the first place, numbness of the fingers.
