We present an unusual case of molluscum contagiosum occurring in epidermal cyst on back of a 5-year-old girl. Histology showed an intradermal cyst containing lamellated horny materials and typical molluscum cells. In Korean literature, 5 such cases were reported. We report an additional case of molluscum occurring in epidermal cyst.

PURPOSE: Postoperative serial serum thyroglobulin (Tg) measurements on levothyroxine (L-T4) therapy in patients with differentiated thyroid carcinoma (DTC) is known to be useful in monitoring tumor progression or regression. The objective of this study was to evaluate the significance of serum Tg levels on L-T4 therapy after surgery. METHODS: To determine the basal serum Tg levels on L-T4 therapy after surgery in patients with DTC, Tg levels during the initial 2 year-period after surgery were analyzed retrospectively in 37 patients who had undergone a total thyroidectomy for papillary thyroid carcinoma with (Group 2) or without (Group 1) palpable cervical lymph node metastasis. The Tg levels had been measured 1 to 4 times for each patient with total of 53 and 35 times in Group 1 and Group 2 respectively. RESULTS: The basal Tg levels in Group 1 were all less than 4 ng/mL with 79.3% less than 2 ng/mL, and those in Group 2 were all less than 9 ng/mL with 71.4% less than 2 ng/mL. CONCLUSION: The data suggests that the postoperative serum Tg level of 10 ng/mL can be a useful reference value in long-term follow-up after total thyroidectomy for patients with DTC.

PURPOSE: We report one case of macular injury by Nd: YAG laser during aiming of the laser beam. METHODS: A 34-year-old man injured his right eye accidentally while aiming a Nd: YAG laser. He was referred to our ophthalmologic department because of diminished vision in the right eye at 2 hours after the accident. Central scotoma was noted. Best corrected visual acuity was 0.02 in the right eye. On fundus examination there were preretinal hemorrhage on the fovea, a full thickness macular hole of 1/3 optic disc diameter, parafoveal retinal edema and vitreous hemorrhage on inferior fundus. Seven days after the accident, a star shaped subretinal fibrosis and scar formation were seen on fundus examination and fluorescein angiography showed star shaped hyperfluorescence area on the fovea. Three months after the accident preretinal and vitreous hemorrhage were resolved and the macular hole was closed spontaneously, but the subretinal scar and fibrosis progressed and best corrected visual acuity remained as 0.02 in the right eye. RESULTS: Visual acuity was severely decreased due to Nd: YAG laser injury to the macula.

A prominent crista terminalis is a normal anatomic variant which consist of thick muscular bridge within the right atrium. However, it could be often misdiagnosed with an abnormal mass on the transthoracic echocardiography. The case report presented here, describe the findings of transthoracic echocardiography that suggested a right atrial mass in patients with pulmonary embolism. However, subsequent transesophageal echocardiography and cardiac computed tomography/magnetic resonance imaging differentiated a true right atrial mass from a prominent crista terminalis.

PURPOSE: To evaluate the efficacy of power Doppler ultrasonography (PDUS) in depicting renal infarction inrabbits during experimental renal segmental arterial occlusion, and to compare the results with those of CTscanning. MATERIALS AND METHODS: In 28 rabbits weighing 2.5-4kg, the segmental renal artery was occluded throughthe left main renal artery by embolization with Ivalon (Nycomed, Paris, France). Power Doppler ultrasonography andspiral CT scanning were performed before and at 2, 5, 8, 15, and 24 hours, and 3 and 7 days after occlusion of thesegmental renal artery. The location of infarcted areas and collaterals, as seen on PDUS and CT scans, wasevaluated by two radiologists. RESULTS: In all cases, as seen on power Doppler ultrasonography, infaretedareas-when compared with normal parenchyma, clearly demonstrated wedge-shaped perfusion defects in the kidney. Thelocation of the lesion closely corresponded to the location seen during CT scanning. After renal arterialocclusion, transiently congested capsular arteries, which were named 'capsular sign', were seen in 63% ofrabbits in the two and five-hour groups. No significant cortical rim sign was demonstrated on power Dopplerultrasonography, though it was noted on spiral CT at 15 and 24 hours, and 3 and 7 days after renal arterialocclusion. CONCLUSION: Power Doppler ultrasonography was useful for the diagnosis of renal infarction. Congestedcapsular artery seen in the early stage of renal infarction might be a characteristic finding of this condition,as seen on power Doppler ultrasonography.

Neurilemmoma is the most frequent solitary tumor of the peripheral nerves. It may occur anywhere in the body, but their occurrence in the penis is rare and unusual. Treatment of this lesion is simple surgical excision. We report a case of neurilemmoma of the penis in a 27 year-old male and review the literature.

The authors present a case of unilateral agenesis of internal carotid artery associated with an aneurysm at the unusual site. A 22-years old female was admitted with sudden headache and nausea. She was alert on admission and no focal neurologic deficit was detected. Brain computed tomography(CT) scan showed subarachnoid hemorrhage. In the cerebral angiography, right internal carotid artery was absent and an aneurysm was arisen from the junction of the right middle cerebral artery and posterior communicating artery. The blood supply of the right anterior cerebral artery was maintained from the left internal carotid artery via the anterior commuicating artery. The territory of the right middle cerebral artery was supplied from the basilar artery through enlarged right posterior communicating artery. Direct clipping of the aneurismal neck was performed through right pterional approach. In the postoperative high resolution CT scan, there was no carotid canal in the right skull base suggesting agenesis of the right internal carotid artery.

PURPOSE: Appendicitis represents one of the most common surgical disorders. Typically, the diagnosis can be made from well established clinical criteria, with an acceptable negative appendectomy rate from 7~25%. However, when surgical intervention is performed in the patients suspected of having appendicitis but with equivocal clinical findings, the negative appendectomy rate approaches 50%. Routine contrast-enhanced computed tomography (CECT) has described as an accurate diagnostic imaging modality in patients with suspected appendicitis. We evaluated the role of intravenous CECT (iCECT) in patients suspected of having appendicitis but with equivocal clinical exams. METHODS: Eighty seven consecutive patients who were thought to have appendicitis but with equivocal clinical findings and/or physical exams were imaged by iCECT over 18 months period. Intravenous contrast-enhanced, spiral abdominal and pelvic images were obtained using 7.5 mm cuts. iCECT images were interpreted by a board-certified radiologist. Main outcome measures included iCECT sensitivity, specificity, positive predictive value (PPV), negative predictive value (NPV), accurary and negative appendectomy rate in the diagnosis of acute appendicitis, and determining the impact iCECT on the clinical management of the patient population. RESULTS: A group of 87 patients consisting of 36 males (41.4 %) and 51 females (58.6%) with median age of 32 years (range 12 to 75 years) were imaged with iCECT to evaluate suspected appendicitis. Of the 87 iCECTs performed, 8 false-positive and 2 false-negative readings were identified, resulting in a sensitivity of 93.5%, specificity of 85.7%, PPV of 78.4%, NPV of 96%, and an overall accuracy of 88.5%. With regard to clinical management, 100% (31/31) of patients with appendicitis, and 4% (2/50) of patients without appendicitis underwent appendectomy. Therefore, the overall negative appendectomy rate was 6.1% (2/33). CONCLUSION: iCECT is a useful diagnostic imaging modality for patients suspected of having acute appendicitis but with equivocal clinical findings and/or physical exams. iCECT is particularly useful in excluding the diagnosis of appendicitis in those without disease.

The vast majority of schwannomas occur on cranial nerves, and rarely in the retroperitoneum. Solitary schwannoma in the psoas muscle is extremely rare. The authors present a case of retroperitoneal neoplasm in the psoas muscle identified as schwannoma which is not associated with von Recklinghausen's disease. A 68 years old female patient was admitted because of low back pain and weakness at the left leg. CT and MRI revealed a large cystic mass with well-defined margin and multiple internal septation within the left psoas muscle. The tumor was totally extirpated and histologically confirmed as a schwannoma.
