Alinson (pseudonym) is a Canadian who came to China with his wife and children because he married a Chinese wife. 51 years old, four months ago, he was always physically fit and felt weakness in his legs and had difficulty lifting his hands to hold things. He went to a hospital in Shanghai to find out the cervical spine disease, and then went to another tertiary hospital in Shanghai orthopedic department, and had an MRI suggesting lumbar disc herniation, the doctor suggested him surgery, but he refused. Last month, he found that he sometimes had shortness of breath and coughing when he walked, and he went to the hospital and found alveoli. As Alinson’s walking became worse and worse, and he would sometimes fall, his wife decided to go to a top-notch hospital. The doctor gave him a detailed physical examination and diagnosed him with “chronic Guillain-Barre syndrome” and gave him an electromyogram, and when the electromyogram results came out, his wife wanted to hospitalize him, but she couldn’t get another appointment with this specialist for 2 weeks. Alinson’s condition was worsening day by day, and he could not walk independently anymore, and he was fatigued, had weak speech, and sometimes struggled to eat sandwiches. The wife remembered the hospital at home – Shanghai Tongren Hospital, why not come to try? Alinson did not know Chinese and had to rely on an interpreter to communicate with the doctors and nurses. Director Du Ailian talked to him in English and uncovered a lot of unknown medical history: progressive limb weakness for 4 months, significant fatigue, sometimes chest tightness and shortness of breath, difficulty swallowing, back pain, and asked about the patient’s weight loss in the last 4 months. “You can’t imagine how strong I was”, Alinson replied. Combined with the physical examination of the lower extremities with grade 3 muscle strength, loss of tendon reflexes, and an electromyogram suggesting a significant decrease in nerve conduction velocity and amplitude, “the peripheral neuropathy was clear,” but the patient’s weight loss and chest tightness and shortness of breath made her flash a scary thought: paraneoplastic syndrome! It was possible that there was a malignant tumor somewhere behind the peripheral neuropathy causing the patient’s set of symptoms. Three days later, Alinson’s preliminary results came back and, as expected, the doctor found a mass in his right hilar region. Dr. Du told the patient’s wife the bad news, and she continued nursing with her 2 children, holding back her tears, sometimes unable to resist losing her temper with them, and with her 2 beautiful mixed-race children still confused and unaware of what was going on. But Alinson seemed to notice something, “How about my lung?” Alinson asked. His wife replied, “Your lungs need further examination. Alinson sat alone in bed, looking visibly depressed, and could hardly imagine how difficulty walking could be linked to lung cancer. Dr. Du explained to him the possible mechanisms of occurrence by drawing diagrams, 1 of which was that the tumor produced antibodies, which bound to receptors on the nerve roots and damaged them, causing peripheral neuropathy, and suggested that he apply gammaglobulin to improve his neurological symptoms. But Alinson was clearly more worried about the lung cancer, and he quickly contacted his parents and loved ones in Canada and decided to return home for treatment. Yes, there are his relatives there and his familiar language. We believe he can get the best care in his hometown and silently wish him a speedy recovery!
