A large superior mediastinal mass was found incidentally by ultrasonography in a 60-year-old man. There was an abnormal accumulation of Tl-201 in the lower pole of left thyroid gland, extending into left superior mediastinum on Tc-99m pertechnetate/Tl-201 subtraction scan. Laboratory findings relating thyroid and parathyroid were all within normal range. We considered the mass as a non-functioning parathyroid adenoma tentatively. However, subsequent surgery and pathologic examination revealed the mass to be a benign mixed thymoma. We report a case of patient with thymoma showing unusual Tc-99m pertechnetate/Tl-201 subtraction imaging and laboratory findings, and suggest to consider the possibility of other mediastinal tumors rather than parathyroid adenoma.

N/A Temporomandibular (TM) joint pain results from many etiologic factors. The aim of this study was to evaluate the utility of Bone SPECT in patients with TM joint pain. The subjects were 34 patients with TM joint pain. All patients underwent plain radiography, planar bone scan, and Bone SPECT. The intensity of radioisotope uptake at TM joint was graded into three; no increased uptake above three background activity as grade 0, uptake similar to occipital bone as grade I, and uptake similar to maxillary sinus as grade II. Clinical findings and therapeutic methods were reviewed. Twenty-seven patients (80%) out of 34 patients with TM joint pain had increased uptake in bone SPECT. Twenty-one (78%) out of 27 patients had increased uptake in the mandibular condyle and remaining six patients (22%) had uptake in the mandibular and maxillary arch, which proved to be dental problem. Seven patients out of 34 were grade as 0, four (12%) were grade I, 23 (68%) were grade II. Four patients with grade I had clicking sound and symptoms which were subsided with medication in all cases. Among 23 patients with grade II, 7 patients had clicking sound and 14 patients underwent medication and decompression therapy. With Planar bone scan, 11 cases (32%) had increased uptake in TM joint area. Plain radiography revealed narrowing, distension, erosion and limitation of TM joint in 16 cases (47%). Bone SPECT can be valuable for screening and managing the patients with TM joint pain. Patients with grade II needed intensive treatment such as joint aspiration. However degree of the radioisotope uptake did not well correlated with clinical symptoms.

N/A In order to establish the clinical significance of pubic bone uptake of radionuclide on Tc- 99m-MDP bone scintigraphs, we analyzed uptake patterns of normal adult pubic bone in 300 randomly sampled subjects. Bone scintigraphy was performed in each patient for the reasons other than pubic or pelvic problems. One-hundred-fifty-four were men and 146 women. The age ranged from 8 to 78 years. The pubic uptake was graded arbitrarily into 4 grades by comparing the pubic uptake density with that of L5 vertebra. Thus, grade I was defined as the L5 density greater than the pubic density, grade II as the L5 density equals to the pubic density, grade III as the L5 density less than the pubic density, and grade IV as the L5 density much less than the pubic density. Statistical analysis revealed negative trend in the pubic uptake from grade IV to grade I with age. There was no sexual difference in the pubic uptake. The women in the 3rd and 4th decades disclosed higher pubic uptake (grades III, IV) probably due to pregnancy and labor.

Sternocostoclavicular hyperostosis (SCCH) is a chronic, nonsuppurative inflammatory disease involving sternum, clavicle, upper ribs and its adjacent soft tissue. It is a relatively newly described syndrome, characterized by ossification in the region between the clavicle and the first rib, and hyperostosis of the medial end of the clavicle with simultaneous involvement of the sternum and juxtasterna1 ribs. We experienced one case of sternocostoclavicular hyperostosis, diagnosed by pinhole bone scintigraphy. This paper describes characteristic pinhole scintigraphic findings of SCCH, with comparative study with radiographic and pathologic findings.

목적: 최근 고혈압, 당뇨병, 고지혈증, 흡연과 더불어 비만이 심혈관 질환 발생을 유발하는 중요 위험 인자로 대두되고 있다. 본 연구에서는 내장 비만의 양을 측정할 수 있는 복부 지방 전산화단층촬영 (Abdominal fat CT)을 이용하여 단일 기관에서 투석 중인 혈액투석 및 복막투석 환자에서 내장 비만의 유병률을 알아보고자 하였다. 방법: 2007년1월부터 2007년3월까지 가톨릭대학교 의정부성모병원 신장내과 외래에서 투석 치료를 받는 환자를 대상으로 복부 지방 전산화단층촬영을 시행하여 내장 비만 양을 측정하였다. 내장 비만은 복부 내장지방면적이 103.8 cm2 이상인 경우로 정의하였고, 의무기록을 통해 후향적으로 투석기간, 지방수치, 신체질량지수, 당뇨병 여부 등을 분석하였다. 결과: 총 172명의 대상 환자 중 혈액투석 환자는 65명, 복막투석 환자는 67명이었다. 복막투석 환자의 평균체중 (60.1±9.3 kg vs. 67.0±12.2 kg, p=0.000), 평균 BMI (22.7±3.2 kg/m2 vs. 25.0±3.3 kg/m2, p=0.000), 중성지방 양 (146.3±83.2 mg/dL vs. 186.2±122.3 mg/dL, p= 0.031)이 혈액투석 환자에 비해 높았다. 또한 혈액투석군에 비해 평균 내장지방 면적 (97.3±50.2 cm2 vs. 122.8±47.5 cm2, p=0.003), 내장 비만 유병률 (35.4% vs. 56.7%, p= 0.014)이 복막투석군에서 높았으나, 복막투석군에서는 내장 지방면적과 신체질량지수 사이의 유의한 상관관계를 보이지 않았다 (r=0.154, p=0.214). 양 군 모두 고령 환자에서 내장 비만의 유병률이 높았다 (≥65) (p=0.004). 결론: 본 연구를 통해 혈액투석군에 비해 복막투석군의 내장 비만 발생률이 높았다. 추가적인 연구가 필요하겠으나 복막투석 환자에서 대사 증후군의 발생을 예방하기 위한 체중 및 영양 상태의 적극적인 조절이 필요할 것으로 사료된다. Purpose: Visceral obesity is a more reliable indicator of cardiovascular risk factor than BMI. Our study was designed to compare the prevalence of visceral obesity in peritoneal dialysis (PD) patients to hemodialysis (HD) patients with abdominal fat CT in a single center. Methods: In this cross sectional study, the result of abdominal fat CT of dialysis patients was investigated from January, 2007 to March, 2007 in Uijeongbu St. Mary`s Hospital. To evaluate the risk factors related to visceral obesity, we analyzed patients` medical records such as duration of dialysis, lipid profiles, anthropometric data and the presence of DM. Results: We enrolled 65 HD patients and 67 PD patients. PD group had higher mean body weight, mean body mass index (BMI), and triglyceride level, compared to HD group. The PD group had higher visceral fat area, measured by abdominal fat CT than HD group. The prevalence of visceral obesity was higher in PD group than HD group. Visceral fat area showed positive co-relation with BMI in HD group, but did not in PD group. The age related prevalence of visceral obesity was significantly increased in the patients with older age group (>65). Conclusion: Our cross sectional study points to the fact that visceral obesity is more common in PD patients than HD patients. It is necessary to control weight and nutritional status, especially in PD patients for preventing metabolic complications.
