Biopsy sample from a<unk> . Magnetic resonance spectroscopy of a<unk>  showing elevated choline and creatine peaks with a decreased NAA peak. Like most brainstem tumors, diagnosing<unk>  usually involves non-invasive brain imaging like MRI, in addition to neurologic physical exam. Biopsies and other procedures are very uncommon. Similar to<unk> ,<unk>  midline<unk> s (DMG) often fall into similar categories for both diagnosis and treatment as<unk>  and are often categorized together. More recently, biopsies are performed so that the best option for clinical trials can be chosen. In studies resulting from the<unk> /DMG Registry and in connection with the<unk> /DMG Collaborative, statistics reveal that approximately 150–300 patients are diagnosed with<unk>  in the USA per year, the median age of patients with<unk>  is approximately 6–7 years old and the male/female ratio of<unk>  patients is 1:1.
