Core Tip

Core Tip: Brain tumors are the most common solid tumors in children. Common presentations include headache, nausea and vomiting, gait abnormality, and epileptic seizure; however, some symptoms can be insidious and misleading. Here, we report a 7-year-old boy who presented with recurrent cyanosis and tachypnea after exercise for 2 years. Type II respiratory failure, pulmonary heart disease, liver injury, and severe obesity were diagnosed. Cyanosis during sleep (peripheral oxygen saturation dropping to 50%-60%) was observed during hospitalization. Sleep-related breathing disorder was suspected. Brain magnetic resonance imaging revealed a cerebellum and brainstem space-occupying lesion. Subsequent tissue biopsy pathology confirmed brainstem pleomorphic xanthoastrocytoma.
