The number of women undergoing breast augmentation surgery with a prosthesis for cosmetic purposes or reconstruction after a mastectomy is steadily increasing.Hematoma is one of complications associated with breast augmentation surgery.It usually occurs early in the postoperative period. It rarely occurs late (after six months). However, chronic hematomas after prosthesis removal have not yet been reported in the radiological literature. We present a case of unilateral chronic organizing hematoma that developed late and grew persistently over long period after breast explantation, mimicking a soft tissue tumor of the chest wall clinically. Meanwhile, characteristic magnetic resonance imaging features of heterogeneous signal intensities on T1-weighted and T2-weighted images and dark signal intensity with a persistent enhancement of the peripheral wall of the lesion were found. These can be used for a differential diagnosis.

Dual left anterior descending artery (LAD) is a rare congenital coronary artery anomaly with a prevalence of approximately 1% in the general population. To date, 10 types of dual LAD artery anomalies have been reported. Among these, type 4 is one of the rarest. Knowledge and recognition of the dual LAD artery are important for correct diagnosis and planning of coronary bypass surgery and percutaneous coronary intervention. We report a case of a 59-year-old male with type 4 dual LAD artery who presented with dyspepsia and sweating for several months and had approximately 50%–70% stenosis in a major diagonal branch off the short LAD artery.

OBJECTIVES: This study aimed to investigate the prospective associations of premenstrual dysphoric disorder (PMDD) with quality of life, socio-occupational function and disability. METHODS: 170 nurses were recruited from two general hospitals. Interviews were made at baseline and at four follow-up points (two mid follicular phases and two late luteal phases of the two consecutive menstrual cycles). The baseline evaluation consisted of sociodemographic characteristics and menstrual history. PMDD was diagnosed by DSM-IV criteria after observation of the two menstrual cycles. The follow-up evaluations were consisted of the World Health Organization Quality of Life-Brief form, the Social and Occupational Functioning Assessment Scale, and the World Health Organization Disability Assessment Scale-II. RESULTS: PMDD was detected 15 (8.8%) of 170 participants. The PMDD group showed significantly worse quality of life and socio-occupational functioning than the none-PMDD group particularly at the late luteal phases. No significant differences were found in sociodemographic characteristics and menstrual history between those with and without PMDD. CONCLUSION: PMDD was prospectively associated with worse quality of life and socio-occupational functioning in this study group.

Korean hemorrhage fever(KHF) is an acute febrile disease with high fever, hypotension, gastrointestinal symptom, hemorrhagic symptom and renal failure. An adult patient with KHF presented with normal EKG on admission and no hypotensive period, subsequently developed dypnea on 10 th hospital days. Pulmonary edema pattern of the chest x-ray, T inversion of EKG and diffuse ventricular dyskinesia of echocardiography apperaed on 10th hospital days, and then disappered on 2 month. We experienced a rare case of KHF associtaed with myocarditis. This case suggests that the Myocarditis can be associated with KHF.

Retroperitoneal liposarcoma is an infrequent, locally aggressive malignancy. We report two cases of huge retroperitoneal liposarcomas. The presence of a palpable abdominal mass was a common symptom of the two patients. Preoperative imaging study showed huge retroperitoneal tumors. Both patients underwent complete surgical resections, and a negative microscopic margin was achieved in both cases. The histopathologic diagnosis was a well-differentiated retroperitoneal liposarcoma. Neither of the two patients developed a recurring tumor during the 1.5 years of follow-up.
