Idiopathic pulmonary fibrosis (IPF) progressing to the final end. Roentgenograms of a 57-year-old female (a) 6 years before diagnosis (normal) and (b) at the time of diagnosis of IPF. The latter reveals a bilateral reticular pattern. (c) High-resolution computed tomography shows mild reticulation. (d) Roentgenogram of the patient 24 months after diagnosis demonstrates worsening of the reticular pattern superimposed on a ground-glass pattern. The patient was admitted with severe breathlessness and productive cough. Her symptoms were severely aggravated in the last 9 months and she was hospitalized many times. She had received corticosteroids and mycophenolate mofetil, which were discontinued months prior to this roentgenogram because of lower respiratory tract infections. At the time of the roentgenogram, she was receiving only proton pump inhibitors. She deteriorated further despite best supportive care and died while on palliation treatment. Our putative diagnosis was IPF progressing to the final end.
