A case of histiocytosis X granuloma localized in the pituitary stalk is reported. Coronal and sagittal magnetic resonance imaging views were useful to determine the precise size and location of the mass lesion. The diagnosis was established immunohistochemically and the patient was treated with low-dose irradiation therapy. After irradiation, the patient improved well without endocrine replacement treatment. The pituitary stalk recovered its normal size with no evidence of recurrence on MRI at 7-year follow-up. We emphasize the importance of MRI before initiating therapy to evaluate the pituitary mass lesion and the effectiveness of low-dose irradiation for isolated histiocytosis X.

The aim of this pictorial essay is to illustrate the distribution of normal findings and various lung diseases on coronal reconstructions as compared with cross-sectional high-resolution CT images. The volumetric CT images were obtained at 120 kVp, 200 mA/rotation, pitch 6:1, and a high-spatial-frequency reconstruction algorithm. The scans were performed using 2.5-mm collimation and reconstructed at 1.25-mm intervals. Coronal reconstructions were obtained at 2.5-mm slice thickness and 2.5-mm intervals. The pictorial includes images of normal anatomy, emphysema, idiopathic pulmonary fibrosis, Langerhans cell histiocytosis, sarcoidosis, bronchiolitis obliterans organizing pneumonia, desquamative interstitial pneumonia, nonspecific interstitial pneumonia, lymphocytic interstitial pneumonia, pulmonary edema, tuberculosis, cytomegalovirus pneumonia, bronchiectasis, and panbronchiolitis.
