본 저자들은 우측 부신에서 발생한 갈색세포종과 인접한 간에서 보이는 국소적인 조영 증강의 영상의학적 소견을 보고하고자 한다. 전산화단층촬영과 자기공명영상의 동맥기 영상에서 인접한 간조직에 국소적인 강한 조영증강이 보였다. 그러나 지연기 영상에서 병변은 정상 간조직과 동일한 감쇄를 보여 잘 구분되지 않았다. 또한 병변은 자기공명 T1, T2 강조 영상에서도 비정상적인 신호강도를 보이지 않았으며 정상 조직과 구분되어 보이지 않았다. 이 조영증강되는 간의 병소는 부신절제술을 시행한지 수개월 후 다시 시행한 수술 후 전산화 단층촬영에서는 저절로 소실되어 보이지 않았다.

Changes of lipocortin 1 (LC1) in the brain induced by immobilization stress were investigated in rats. Rats were immobilized for 0,1,2,3,4, and 5 h, and the brain slices were immunostained with anti-human LC1 antibodl (anti-LC1). Immunoreactivity of LCI (iLC1) was most prominent in neuronal cell bodies and processes of hippocampal CA regions and dentate gyrus. At rest without stress, most of the LC1 in the neuron located in the cytoplasm with the nuclei exhibiting relatively scarce immunoreactivity. Immobilization stress changed this intracellular distribution of LC1 by increasing nuclear LC1. The change was apparent in 1 h and reached the peak by 3 h. However, by 5 h of immobilization, the distribution pattern returned to that of the resting state. This transient nuclear translocation of LC1 was most prominent in $CA_1$ pyramidal neurons, and was not observed in areas other than the hippocampus. Adrenalectomy abolished this transient translocation of LC1. The roles of hippocampal LC1 as a mediator of glucocorticoid feedback signal and/or as an intracellar stress signaling protein could be suggested.

A 59-year-old woman who was diagnosed with malignant pheochromocytoma underwent $^{18}F$-fluorodeoxyglucose positron emission tomography/computed tomography ($^{18}F$-FDG PET/CT). She had undergone left adrenalectomy for pheochromocytoma 4 years previously. Recent multiple metastatic pulmonary nodules were noted on the chest X-ray. After treatment with $^{131}I$-metaiodobenzylguanidine ($^{131}I$-MIBG) with 7.4 GBq, post-therapy $^{131}I$-MIBG scintigraphy depicted multiple distant metastases including lung, liver, abdominal para-aortic and mesenteric lymph nodes. $^{18}F$-FDG PET/CT also depicted multiple metastases in lung, liver, and abdominal para-aortic lymph nodes, but some lesions were not shown. In this case, $^{131}I$-MIBG scintigraphy found additional lesions in metastatic malignant pheochromocytoma.

Adrenocortical carcinoma is a rare type of endocrine malignancy with an annual incidence of approximately 1-2 cases per million. The majority of these tumors secrete cortisol, and a few secrete aldosterone or androgen. Estrogen-secreting adrenocortical carcinomas are extremely rare, irrespective of the secretion status of other adrenocortical hormones. Here, we report the case of a 53-year-old man with a cortisol and estrogen-secreting adrenocortical carcinoma. The patient presented with gynecomastia and abdominal discomfort. Radiological assessment revealed a tumor measuring $21{\times}15.3{\times}12cm$ localized to the retroperitoneum. A hormonal evaluation revealed increased levels of estradiol, dehydroepiandrosterone sulfate, and cortisol. The patient underwent a right adrenalectomy, and the pathological examination revealed an adrenocortical carcinoma with a Weiss' score of 6. After surgery, he was treated with adjuvant radiotherapy. Twenty-one months after treatment, the patient remains alive with no evidence of recurrence.

Adrenal metastasis from papillary thyroid carcinoma is extremely rare. We present herein a patient with adrenal metastases from recurrent papillary carcinoma of the thyroid. A 54 year-old woman had received a total thyroidectomy and postoperative radioactive iodine therapy for locally advanced papillary thyroid carcinoma. One year after initial surgery, distant metastases to multiple organs including right cervical lymph nodes, left upper lung, left 2nd and 3rd ribs, 2nd thoracic vertebra and left adrenal gland were found by 18-FDG-PET-CT whole body scan. She underwent right modified neck dissection, partial resection of left 2nd and 3rd ribs, posterior arch of 2nd thoracic vertebra, left upper lobectomy of lung, and left adrenalectomy. On histologic examination, metastases to the left adrenal gland and cervical lymph nodes were papillary thyroid carcinomas, while other metastatic sites turned out to be anaplastic thyroid carcinomas. Despite aggressive surgery and postoperative adjuvant therapy, her general clinical conditions were getting worse day by day due to regrowing of the anaplastic thyroid carcinomas. To our knowledge, this is the first case reported in Korea.

저자들은 산전 초음파에서 복부 종괴가 발견되어 관찰 도중 복부 팽만과 호흡 부전이 발생하여 방사선요법과 항암요법으로 치료하였던 양측성 선천성 신경모세포종 1례를 문헌 고찰과 함께 보고하는 바이다. 선천성 양측성 신경모세포종의 경우 임상경과를 잘 관찰하고 치료여부를 결정하여야 할 것으로 생각된다.

We report a rare synchronous presentation of primary lung cancer and adrenal pheochromocytoma. A 59-year-old woman was diagnosed with right upper lobe non-small cell lung carcinoma measuring 2.8 cm and a right adrenal gland mass measuring 3.5 cm, which displayed increased metabolic activity on $^{18}F$-fluorodeoxyglucose positron emission tomography-computed tomography. The adrenal lesion was revealed to be asymptomatic. The patient underwent right adrenalectomy and histological examination revealed a pheochromocytoma. Ten days later, right upper lobectomy was performed for lung cancer. This case indicates that incidental adrenal lesions found in cases of resectable primary lung cancer should be investigated.

Primary aldosteronism is characterized by hypertension, hypokalemia, and metabolic alkalosis, associated with excessive aldosterone production and suppressed plasma renin activity. Hypokalemia-induced rhabdomyolysis has been rarely reported in primary aldosteronism patients. This paper reports a case of primary aldosteronism presented with rhabdomyolysis due to severe hypokalemia. A 48-year-old male with a three-year history of hypertension presented himself at the authors' hospital with generalized weakness and myalgia in both legs over a period of several days. His laboratory findings showed hypokalemia (1.8 mEq/L) with elevations of his serum creatine phosphokinase and serum myoglobin. His plasma aldosterone level was also elevated, and his plasma renin activity was reduced. An abdominal computed tomography revealed a 2.0 cm hypodense mass in the left adrenal gland, which suggested adrenal adenoma. The accordingly underwent laparoscopic adrenalectomy. Three months later, his plasma potassium level and blood pressure became normal without the use of medications.

Adrenocorticotropic hormone (ACTH)-producing pheochromocytoma has been rarely reported, whereas only a few cases of Cushing syndrome accompanied by opportunistic infections have been reported. We experienced a patient with pheochromocytoma with ectopic Cushing syndrome complicated by invasive aspergillosis. A 35-year-old woman presented with typical Cushingoid features. Her basal plasma cortisol, ACTH, and 24-hour urine free cortisol levels were significantly high, and 24-hour urine metanephrine and catecholamine levels were slightly elevated. The endogeneous cortisol secretion was not suppressed by either low- or high-dose dexamethasone. Abdominal computed tomography (CT) revealed a heterogeneous enhancing mass measuring approximately 2.5 cm in size in the left adrenal gland. No definitive mass lesion was observed on sellar magnetic resonance imaging. On fluorine-18 fluorodeoxyglucose positron emission tomography/CT, a hypermetabolic nodule was observed in the left upper lung. Thus, we performed a percutaneous needle biopsy, which revealed inflammation, not malignancy. Thereafter, we performed a laparoscopic left adrenalectomy, and its pathologic finding was a pheochromocytoma with positive immunohistostaining for ACTH. After surgery, the biochemistry was normalized, but the clinical course was fatal despite intensive care because of the invasive aspergillosis that included the lungs, retina, and central nervous system.

정상백서를 부신절제한 후 각각의 부신호르몬을 투여하여, 고탄수화물, 고지방, 고단백질식이가 부신절제 백서의 대사에 미치는 영향에 대해 실험한 결과를 요약하면 다음과 같다. 1) 혈당과 뇨당의 변화 혈당은 부신절제로 인하여 감소하였다. 부신절제된 백서는 고탄수화물식이를 했을 경우 혈당이 가장 높았고, corticosterone을 투여하면 고지방, 고단백 식이를 했을 경우 혈당이 유의적으로 증가하였다 (p<0.05). aldosterone을 투여하면 고지방식이를 했을 경우 유의적으로 감소하였으나 다른 식이의 경우는 큰 변화가 없었다. 2) 인슐린과 c-peptide의 변화 인슐린 농도는 corticosterone을 투여하면 고탄수 화물식이와 고단백식이를 했을 경우 대조군보다 낮았으나 유의성은 보이지 않았다. c-peptide농도 역시 corticosterone을 투여하면 감소하였고, aldosterone 투여는 영향을 미치지 않았다. 3) 총콜레스테롤과 중성지발 함량 총콜레스테롤 함량은 부신절제로 인하여 감소하였다. 중성지방 함량은 corticosterone을 투여하면, 고지방, 고단백식이를 했을 경우 대조군에 비하여 유의적으로 증가하였다(p<0.05). 4) 체무게와 식이섭취량 체무게와 식이섭취량은 부신절제로 인하여 감소 하였으나, 고지방식이를 했을 경우는 부신젤제효과가 작았다. corticoxterone을 투여하면 체무게와 식이섭취량이 증가하며, aldosterone은 영향을 미치지 못했다. 식이효율은 aldosterone과 corticoxterone의 투여가 큰 영향을 미치지 않았다. 5) 장기무게 Corticoxterone의 투여로 간의 무게가 식이에 상관없이 증가하였다. 그외의 콩팥, 비장, 고환의 무게는 큰 변화가 없었다.
