Abstract

A 39-year-old female patient presented with a history of longstanding left chest pain and moderate breathing problems. There was no weight loss. Four years earlier she had a traumatic rib fracture on the left side. There was no professional exposure to asbestos. A soft and ill-defined mass was palpable in the left flank. Pulmonary auscultation revealed dampening at base of the left hemithorax. Blood biochemistry was normal. Figure 1 shows a frontal chest radiograph on admission. Figure 2 shows a selected slice of the obtained spiral CT after intravenous injection of iodinated contrast material. Figure 3 demonstrates a coronal T2-weighted (TR = 4.3/TE = 60 ms; Magnetom 1.5 T, Siemens, Erlangen, Germany) image through the lesion. Figure 4. shows an axial T1-weighted fat saturated image (TR = 150/ TE = 4.1 ms) after intravenous injection of gadolinium.
