There is clearly a problem to account for the fluid in the lung, a pleural effusion, her abnormal liver function tests, a tender liver and enlarged lymph nodes in the abdomen. It seems that the CT has not been able to provide a definitive diagnosis. She will require further tests in order to identify the problem. She will likely undergo an MRI scan and multiple blood tests in the first instance. She may need a sample of fluid taking from her lung, called a pleural tap, in order to determine whether the underlying problem may be inflammatory/infective or other causes. She may also need a biopsy, or a sample of tissue taking from her lymph nodes or her liver. It may be a primary lung problem or a primary abdominal problem. Her physician will likely get further opinions from other specialist doctors, such as a hepatologist (liver specialist) and a respiratory/chest physician. She is clearly at the start of her investigative process and you will understandably have concerns and worries. Keep doing your own reading and research and write down any questions you might have. Do not be afraid to take out your list of questions and put them to your daughter s physician at her next appointment.
