ABSTRACT
Renal vein thrombosis (RVT) is not an uncommon condition amongst patients with nephrotic syndrome or malignancy. Septic pulmonary embolism (SPE) is associated with risk factors such as intravenous drug use, pelvic thrombophlebitis, and suppurative processes in the head and neck. However, acute pyelonephritis is a rare cause of RVT and SPE. Case reports on RVT and SPE due to acute pyelonephritis are rare. In most of the earlier cases, patients had underlying conditions such as diabetes mellitus, renal carcinoma, calyceal stones, and hyperhomocysteinemia. We report a case of acute pyelonephritis complicated by RVT and SPE that occurred in a patient without any predisposing risk factors for thromboembolism. RVT and SPE were diagnosed using computed tomography and ventilation/perfusion scan. The patient recovered with antibiotics and anticoagulation therapy without any surgical interventions.

BACKGROUND: Knowledge of size and morphology of the normal trachea is important for airway management and tracheal reconstruction. Conventional radiography is a simple method used to measure the tracheal diameter, but it is not accurate because of the artifacts related to image magnification and overlapping by the shoulder. The purpose of this study was to provide the normal values of the tracheal size and anatomy in Korean adults using Computerized Tomography. MATERIAL AND METHOD: There were 43 men and 34 women included in this study. They were divided into three age groups(group 1, 20-39 years ; group 2, 40-59 yeas ; groups 3,>or=60 years). The anteroposterior and transverse diameters and cross - sectional areas of the trachea were measured at the level of the thoracic inlet(Level 1) and the aortic arch(Level 2). These values obtained at each level were compared between age groups and sexes. RESULT: In 43 men, the anteroposterior / transverse diameters(mean SD in millimeters) of the trachea at levels 1 and 2 were 19.95+/-2.99 / 17.72+/-2.13 and 19.77+/-2.57 / 18.02+/-2.19, respectively. In 34 women, those values at levels 1 and 2 were 15.56+/-2.12 / 14.18+/-2.07 and 15.35+/-1.82 / 15.00+/-1.60, respectively. At both levels, the anteroposterior and transverse diameters were significantly greater in men than in women (p<0.05). The cross-sectional area of the trachea at levels 1 and 2 were 279.14+/-61.37 / 281.93+/-63.97 mm2 in men and 173.29+/-35.81 / 181.88+/-34.74 in women, respectively. They also showed significantly greater values in men than in women(P<0.05). There was no significant difference in diameters and cross-sectional areas of the trachea between age groups. CONCLUSION: There are significant differences in the internal diameter and cross- sectional area of the trachea between men and women in normal Korean adults, while the age difference was insignificant. We believed CT is a relatively accurate and safe way to measure the internal diameter and cross-sectional areas of the trachea.

Granular cell myoblastoma is an uncommon tumor occurring on the skin as a single nodule. The tumor are generally small, the usual size being 0.5 to 2cm in diameter. Its rate of growth is usually slow. It is found in nearly equal distribution in men and women and is most common in the third to fifth decade of life. This is a case report of a 37-year-old woman with solitary nodular mass on right brachial plexus. The histopathology of the lesion revealed the pale cytoplasm filling with characteristic granules. Nerve bundles are often seen among or adjacent to the tumor cells. The histogenesis of this tumor is still disputed but the most accepted theory today is the neural derivation. The treatment of choice is surgical excision.
