OBJECTIVE: We report here on two cases of pseudoaneurysms that were diagnosed using computed tomographic angiography (CTA), with one arising in the superficial temporal artery and the other arising in the occipital artery. METHODS: Case 1: A 29-year-old man presented with a slow growing, pulsatile mass on the left side of his forehead following a blow from a fist 10 days earlier. CTA revealed an 11 x 8 x 11-mm oval pseudoaneurysm arising from the frontal branch of the left superficial temporal artery. Case 2 : A 36-year-old man presented with a pulsatile mass in the right suboccipital region that had been present for the past year. He had no history of direct trauma. CTA revealed a 15 x 8 x 13-mm oval dye-filled sac arising from the right occipital artery. RESULTS: Based on the CTA images, the parent arteries were exposed and ligated proximally and distally to the pseudoaneurysms and then they were completely excised. CONCLUSION: CTA is a minimally invasive technique for making the diagnosis of scalp pseudoaneurysms and CTA is also useful for the preoperative planning.

Transient osteoporosis of the hip is a self-limited condition of uncertain etiology and pathogenesis that affects young and middle aged adults. Even its clinical features are similar to the features of osteonecrosis the prognosis and clinical end result are quite different. So differential diagnosis between the two is very important. We present a case of transient osteoporosis of the hip in middle aged man, which was completely reeovered after conservative treatment.

Degenerative spondylolisthesis, which occurs frequently in middle-aged women, is a disease that causes canal stenosis of the lumbar spine and low back pain. Although the clinical features have been described characteristically, its pathogenic mechanism and therapeutic principles are still to be clarified. Some investigators have claimed that the disease originates from morphologic abnormalities of laminae and facet joints or that it is primarily due to degeneration of the intervertebral disks and degenerative changes of the facet joints. We selected two groups of patients retrospectively. The one was a group of patient who had normal findings on their magnetic resonance imaging(Group I ) and the other was a group of patients who showed degenerative spondylolisthesis at L4-5 and had been managed surgically(Group II ). We measured the total lordosis from Ll to S 1 and segmental lordosis of L3-4, L4-5 and LS-S 1 in both groups by Cobbs method. In group 3, we measured the degree of slippage of the L4 vertebral body and investigated the associated congenital anomalies of the lumbosacral vertebra on simple anteroposterior and lateral radiographs in both groups. And we measured the facet joint angles of the L3-4, L4-5 and L5-Sl at both side on MRI. Then we analysed the results statistically and got the following conclusions. 1. In Group I, total lordosis decreased significantly. The segmental lordosis of L4-5 and LS-S1 decreased, too, but the segmental lordosis of L3-4 increased. 2. The facet joint angles of L4-5 in Group I increased significantly in both sides. 3. The intercrestal line was lower in Group I than in Group II. 4. The degree of slip was not related with the facet joint angles of L4-5.

Primary role of ultrasound in patients with thyroid nodule is to determine the multiplicity and detect occult carcinoma. We analyzed US findings of 53 thyroid carcinomas with multiple nodular lesions from january 1988 to december 1991. The results were as follows: 1. 109 malignant nodules in 53 cases and 24 benign in 23 were comfirmed. 2. The nature of the masses were solid in 72 malignant nodules (74.2%), and complex in 25 (25.8%) of which 19 were predominantly solid. 3. The echo pattern of the solid and solid predominant masses were hypoechoic in 78 malignant nodules (80.4%), hyperechoic in 10 (10.3%), and isoechoic in 3 (9.3%) 4. Internal punctate calcifications within the masses were observed in 31 malignant nodules (31.9%). 5. Halo sign was present in 16 malignant nodules(16.5%). 6. The preoperative sonographic diagnosis of thyroid carcinoma was made in 39.4% of 53 cases with multiple nodules on US. In conclusion, the number, and halo formation of nodules were insignificant to differentiate the benign nodule from the malignant. The heterogeneous hypoechoic nodules with size greater than 4cm, multiple stippled calcifications, displacement of the trachea or other surrounding structures of combined lymph node enlargements seem to indicate the possibility of malignancy.
