PURPOSE: To evaluate the pattern of distant lymph node metastasis in colorectal carcinoma and its correlation with distant organ metastasis. MATERIALS AND METHODS: We retrospectively reviewed abdominal CT scans of 46 patients with pathologically proven colorectal carcinoma. RESULTS: The incidence of distant lymphadenopathy in colorectal carcinoma was 30.4%(14/46). The most commonly involved distant lymph node was the left paraortic lymph node below the renal hilum(9/25). The most common type of distant lymphadenopathy was solitary type(7/14) and all of these lymphadenopathies were noted in the left paraortic lymph node below the renal hilum. Six cases of left sided colorectal carcinoma showed left paraortic lymphadenopathy with solitary type. The incidence of distant organ metastasis was 17. 4%(8/46) and markedly increased if distant lymphadenopathy was multiple and confluent, or confluent type(5/7). CONCLUSION: The incidence of distant lymphadenopathy in colorectal carcinoma was not high and the most common lymphadenopathy was the left paraaortic lymph node with solitary type below the renal hilum. The possibility of distant organ metastasis was high if distant lymphadenopathy was multiple and confluent, or confluent type.

PURPOSE: To evaluate the MR appearance of the accessory hepatic veins. MATERIALS AND METHODS: The study included 87 consecutive patients for whom abdominal MR images were obtained. The subjects who had liver lesion or hepatic vascular abnormalities were excluded. Couinaud classified accessory hepatic veins into inferior and middle right hepatic veins. Our major interests were evaluation of the incidence, morphology, and location of the accessory hepatic vein. RESULTS: Inferior right hepatic vein was demonstrated in 43 out of 87 patients(49%). The morphology was linear in 35 patients(80.5%), and V-shaped in 8 patients(19.5%). In 40 patients(93%), the inferior right hepatic vein was located in the posteroinferior aspect of the right lobe. Middle right hepatic vein was demonstrated in 7 out of 87 patients(8%). All were single linear in morphology, combined with the inferior right hepatic vein, and located between the right hepatic vein and inferior right hepatic vein. CONCLUSION: The accessory hepatic vein was demonstrated in 49% among the Korean adult population, and was located in posteroinferior portion of the liver, in 93%.

To determine size and shape discrepancy between the bone of Korean women and the prostheses in total knee arthroplasty, the height(antero-posterior length) and width(medio-lateral length) of the distal femur and the proximal tibia were measured at the bone resection level for 104 knees of 62 female patients who underwent primary total knee arthroplasty and compared with the same parameters of the total knee prostheses designed by five different companies. On the condition that the height of the prostheses matched with each cases of the bone were optimal, the difference in the width was evaluated, and the criteria of the discrepancy were overhang if the width of the prosthesis was larger than bone, optimal if width of the prosthesis was same or smaller and difference was within 5 mm, and down-size if smaller and difference was over Smm. In femoral prostheses, 34.6% of all were optimal, 13.1%, overhang and 52.3%, down-size. In tibial prosthesis, 54.1% of all were optimal, 13.9%, overhang and 32%, down-size. In conclusion, although further investigation for clinical application is needed, there were discrepancies in size and shape between the femur and tibia of Korean women and total knee prostheses and improvement in design should be considered.

Clinical presentation of supplementary motor area (SMA) syndrome includes complete akinesia of the contralateral side of the body and mutism, with secondary recovery of neurologic deficit. Multi-joint coordination is frequently impaired following the development of a brain lesion and is generally restricted by abnormal patterns of muscle activation within the hemiparetic limb, clinically termed muscle synergies. However, no work to date has confirmed this observation with the aid of objective methods, such as gait analysis, and the development of reflex pattern has not been suggested as a possible cause. We describe two unusual cases of flexor synergy after tumor resection of SMA lesions.

59 children seen from Jan. 1990 to Jun. 1994 with epilepsy were retrospectively reviewed to evaluate the tendency of recurrence and the risk factors after the antiepileptic drug discontinuation. The population consisted of 59 children who were seizure free for more than 2 years and followed up for more than 1 year after the discontinuation via department of pediatrics, Yonsei University, Wonju College of Medicine. We analyzed risk factors of recurrence(age of seizure onset, seizure frequency before treatment, interval from seizure onset to start of treatment, duration from neurologic disorders, and EEG done just before discontinuation) between non-recurrent group(43 patients) and recurrent group(16 patients). The results were as follows: 1) In 59 patients with epilepsy, 16(27.1%) patients showed recurrence after the discontinuation and 14(87.5%) patients of those were developed during taperring and within less than 1 year. The probability of recurrent seizure by Kaplan-Meier curve at 12 and 24 months after discontinuation are 23.7% and 33.6% respectively. 2) There were significant differences on seizure frequency before treatement, duration from start of treatment to control (9.5months vs 31.1months), and associated neurologic disorders(11.6% vs. 56.2%) between non-recurrent and recurrent group. 3) There were no significant differences on age at seizure onset(70.6 months vs. 58.5months), interval from seizure onset to start of treatment(9.5months vs. 6.6months), length of seizure free(49.7months vs 39.3months), abnormal EEG finding done just before withdrawal(23.2% vs. 25.0% ) between non-recurrent and recurrent group.

Kawasaki disease is described by fever lasting five days or more, bilateral conjunctival injection, changes of lips and oral cavity, polymorphous exanthema, acute non-purulent cervical lymphadenopathy, and changes of extremities. Atypical Kawasaki disease is defined as fewer than 4 of 6 criteria described above including coronary artery abnormalities. Especially, atypical clinical manifestations of Kawasaki disease appear in infants younger than 6 months old of age. Thus we recommend echocardiography in early infancy who has prolonged fever in order to diagnose atypical Kawasaki disease and treat early. We have experienced three cases of atypical Kawasaki disease with coronary aneurysm who were admitted because of fever and revealed coronary aneurysm on echocardiography.

PURPOSE: The differentiation between renal cell carcinoma(RCC) and transitional cell carcinoma(TCC) is important due to the different methods of treatment and prognosis. But occasionally it is difficult to draw a distinction between the two diseases when renal parenchyme and renal collecting systems are invaded simultaneously. MATERIAL AND METHOD: We reviewed CT scans of 37 cases of renal cell carcinoma and 12 cases of transitional cell carcinoma which showed involvement of renal parenchyma and renal sinus fat on CT. Retrospective analysis was performed by 3 abdominal radiologists. Check points were renalcontour bulging or reniform shape, location of mass center, intact parenchyme overlying the tumor, cystic change, calcification, LN metastasis, vessel invasion, and perirenal extention. RESULT:There were renal contour bulging due to the tumor mass in 33 out of 37 cases of renal cellcarcinima, wherea and nine of 12 cases of transitional cell carcinoma maintained the reniform appearance. This is significant statiscal difference between the two(p<0.005). Center of all TCCs were located in the renal sinus, and 24 out of 35 cases of RCC were located in the cortex(p<0.005). Thirty-six out of 37 cases of RCC lost the overlying parenchyma, whereas 4 out of 9 cases of well enhanced TCC had intact overlying parenchyma(p<0.005) RCC showed uptic change within the tumor mags in 31 cases which was significanity higher than the 4 cases in TCC(p<0.05). CONCLUSION: CT findings of renal cell carcinoma are contour bulging, peripheral location, obliteration of parenchyma, and cystic change. Findings of transitional cell carcinoma are reniform appearance, central location within the kidney, intact overlying parenchyma, and rare cystic change.
