Left lobe of the liver draping around the spleen: a pitfall in computed tomography diagnosis of perisplenic hematoma.
Computed tomography scanning has become one of the prime modalities in the diagnosis of trauma to the spleen (1-6). We present three cases of potential pitfall in computed tomography scan diagnosis. In the first case, computed tomography scan showed a high-attenuation perisplenic density in the superio-lateral region of the spleen compatible with a perisplenic hematoma. ⋯ On careful screening, this was traced as part of the left lobe of the liver. The lower attenuation value of the liver was due to fatty infiltration. The importance of performing computed tomography with and without contrast infusion in these cases is discussed.

Case Reports
Fibrobullous disease of the upper lobes: an extraskeletal manifestation of ankylosing spondylitis.
Fibrobullous disease of the upper lobes of the lungs is a rare extraskeletal manifestation of ankylosing spondylitis, occurring in 1.3% of patients with ankylosing spondylitis. We present a patient with this disease, and discuss this pulmonary manifestation. Because the radiographic appearance of the chest in this disease resembles that in tuberculosis, many patients are misdiagnosed and treated for tuberculosis despite negative bacteriology. Computed tomography is useful in delineating the extent of pleural thickening, bullous changes, volume loss, parenchymal fibrosis, and bronchiectasis, as well as identifying or excluding an intracavitary pulmonary mycetoma.
