Positron emission tomography-computed tomography images on admission. (A) Coronal and sagittal positron emission tomography images on admission showing 18F-fluorodeoxyglucose uptake in peripharyngeal, axillary, mediastinal, hilar, iliac and inguinal lymph nodes and spleen. An arrow indicates 18F-fluorodeoxyglucose uptake at submandibular dental roots, suggesting submandibular periodontitis. (B) Fused positron emission tomography-computed tomography image showing left hilar lymph node swelling with moderate 18F-fluorodeoxyglucose uptake. (C) Fused positron emission tomography-computed tomography image showing remarkable 18F-fluorodeoxyglucose uptake in the spleen.
