Hi, Thanks for writing in. A small tumor in the adrenal gland is most likely a benign one. Adrenal tumors can be functional or non functional. If there is a small non functional tumor in you then treatment is not required. However periodic evaluation by doing scans is recommended to judge any increase in growth of the tumor. Basal pneumonia is infection of the basal segments of the lungs. The basal segments refer to lower lobe segments and you might be having pneumonia in one of the lungs involving the lower lobes basal segments. There need not be fever in every patient having pneumonia in the early stages. Some can only present with chest pain and discomfort and coughing. It is important that you get it checked by a pulmonologist and take required medication and get treated early. Delaying treatment might cause severe pneumonia and complication. Please do not worry.
