Measurement of the normal pituitary gland height was performed on magnetic resonance (MR) images of 144 subjects with no known or suspected pituitary or hypothalamic diseases. Midsagittal T1 weighted images (T1WI) were used for measurement, and mean vertical height according to age and sex group was obtained. In all age groups, the pituitary height was greater in females than in meles, The group of 0-9 years in both genders showed the minimum mean pituitary height, The maximum mean height was observed in the 10-19 years age group in both genders. The height gradually decreased with increasing age after age 20 years. There was no subject with a height more than 9.0 mm in females or 8.0 mm in males. In conclusion the measurement of the normal pituitary pland height using mid sagittal MR imaging can be used for the evaluation of the pituitary gland lesions.

Primary tumors of the heart are rare, and one-third of them are malignant. The most common malignant intracardiac tumor is angiosarcoma, which usually involves right atrium. MR features in one patients with right atrial angiosarcoma is presented and the literature briefly reviewed. Angiosarcoma demonstrated slightly heterogeneous intermediate signal intensity on T1-weighted images, high signal intensity on T2-weighted images and higher signal intensity on Gd-DTPA enhanced images. MRI provided more information regarding the extent of the tumor than 2D echocardiography or CT.

Teratoma is very rarely developed in the third ventricle. We report a case of third ventricular mature teraroma in 12 year old boy with headache and precocious puberty. In TlWl and Gd-DTPA enhanced TlWl, the mass in the third ventricle showed mixed signal intensities with signal void and partial contrast enhancement. The tumor was confirmed as a mature teratoma including teeth and fatty tissue.

PURPOSE: To report a case of primary extramedullary plasmacytoma which is rare in the orbit. METHODS: A 72 year-old man was referred for the evaluation of a slowly developing proptosis in the right eye. A CT scan revealed the orbital mass which involved optic nerve and surrounding tissues. Incisional biopsy via lower lid was performed. RESULTS: Histopathologic examination confirmed the findings of plasmacytoma. Systemic evaluation including bone marrow biopsy, clinical and radiologic evaluation showed no evidence for multiple myeloma. Taken together we diagnosed the orbital lesion as a primary extramedullary plasmacytoma. He was treated with radiation therapy and followed for 6months without evidence of new lesion or systemic disease. CONCLUSIONS: We experienced a case of primary extramedullary plasmacytoma which is rare in the orbit. Continuing careful observation is warranted because of its variable natural course and prognosis.

PURPOSE: Our purpose in this study is to evaluate the effectiveness of bronchial and nonbronchial systemic arteries for the control of hemoptysis. MATERIALS AND METHODS: Seventy patients with massive or recurrent hemoptysis underwent percutaneous transcatheter embolotherapy between 1991 and 1993. Retrospectively we reviewed 77 cases of bronchial artery embotization and 32 cases of nonbronchial systemic artery embolization in the 70 patients. RESULTS: Immdiate control of hemoptysis was achieved in 33 of 39 patients with massive hemoptysis(84.6%) and 20 of 24 patients with recurrent hemopt ysis(83.3%). In 32 cases, nonbronchial systemic arteries contributed significantly to areas of pathologic pulmonary tissue and frequently were the major arterial supply. CONCLUSION: Bronchial artery embolization is an effective and life saving procedure in non-surgical candidates. Recognition and occlusion of nonbronchial systemic arteries that feed to hypervascular pulmonary lesions is essential for successful percutaneous embolotherapy of hemoptysis.
