When these symptoms occur with concurrent mucocutaneous ulcerations, they raise suspicion of acute optic neuropathy in Behçets Disease. Progressive optic atrophy may result in decreased visual acuity or color vision. Intracranial hypertension with papilledema may be present.Episcleritis may occur, which causes eye redness and mild pain, without a significant impact on vision. Bowels
Gastrointestinal (GI) manifestations include abdominal pain, nausea, and diarrhea with or without blood, and they often involve the ileocecal valve. Some patients with BD experience abdominal tenderness, bloating, and general abdominal discomfort. When mild this can resemble irritable bowel syndrome; more severe cases bear similarities to inflammatory bowel diseases such as ulcerative colitis or Crohns. Lungs
Lung involvement is typically in the form of hemoptysis, pleuritis, cough, or fever, and in severe cases can be life-threatening if the outlet pulmonary artery develops an aneurysm which ruptures causing severe vascular collapse and death from bleeding in the lungs. Nodules, consolidations, cavities and ground glass lesions are common in patients with pulmonary involvement. Pulmonary artery thrombosis may occur. Joints
Arthritis is seen in up to half of people, and is usually a non-erosive poly or oligoarthritis primarily of the large joints of the lower extremities. Brain
Central nervous system (CNS) involvement most often occurs as a chronic meningoencephalitis. Lesions tend to occur in the brainstem, the basal ganglia and deep hemispheric white matter and may resemble those of multiple sclerosis (MS).
In the case of large sacrococcygeal teratomas, a significant portion of the fetus blood flow is redirected toward the teratoma (a phenomenon called steal syndrome), causing heart failure, or hydrops, of the fetus. In certain cases, fetal surgery may be indicated. Beyond the newborn period, symptoms of a teratoma depend on its location and organ of origin. Ovarian teratomas often present with abdominal or pelvic pain, caused by torsion of the ovary or irritation of its ligaments. A recently discovered condition where ovarian teratomas cause encephalitis associated with antibodies against the N-methyl-D-aspartate receptor antibody (NMDAR) - often referred to as "anti-NMDA receptor encephalitis", was identified as a serious complication. Patients develop a multistage illness that progresses from psychosis, memory deficits, seizures, and language disintegration into a state of unresponsiveness with catatonic features often associated with abnormal movements, and autonomic and breathing instability. Testicular teratomas present as a palpable mass in the testis; mediastinal teratomas often cause compression of the lungs or the airways and may present with chest pain and/or respiratory symptoms. Some teratomas contain yolk sac elements, which secrete alpha-fetoprotein. Its detection may help to confirm the diagnosis and is often used as a marker for recurrence or treatment efficacy, but is rarely the method of initial diagnosis. (Maternal serum alpha-fetoprotein is a useful screening test for other fetal conditions, including Down syndrome, spina bifida, and abdominal wall defects such as gastroschisis.) Classification
Regardless of location in the body, a teratoma is classified according to a cancer staging system.
