OBJECTIVE To describe a case of retroperitoneal mature teratoma presenting as metastasis of a testicular mixed germ cell tumor in a thirty year old man who had lumbar and abdominal pain and mass sensation in the left hemiabdomen. METHODS Abdominal ultrasound and thoracic-abdominal-pelvic CT multidetector scan were performed, and then after a Doppler ultrasound study of the testicles. Surgical...

Primary hyperparathyroidism (pHPT) is defined by the excess level of parathyroid hormone (PTH). Parathyroid adenoma is responsible for about 80% of all pHPT. Parathyroid adenoma with cystic feature and atypical pathology is recognized as a rare entity. Technetium-99m methoxy isobutyl isonitrile ([99mTc]Tc-MIBI) scintigraphy has favorable detection rate for ectopic gland as well as th...

Introduction: Infarction is a very rare complication of fibroadenoma. Diagnosis such situation not easy. Case Presentation: 23-year-old woman with painful tumor the right breast mild erythema at periareolar region. Breast ultrasound shows heterogeneous lesion 31×30 mm, in retroareolar well-defined borders, and does present vascular flow inside. Antibiotic treatment was administered without impr...

controversies existed regarding the relationship between non-neoplastic cystic lesions and solid tumor masses. The so-called COC shows great diversity in the spectrum of clinical behavior and histopathological features, including cystic, solid (neoplastic), and aggressive (malignant) variants, because of which different categorization and nomenclature for the lesion have been proposed. In the 2...

Mucinous cystic neoplasm of the liver (MCN) is uncommon and sometimes misdiagnosed as Echinococcal cyst, especially when patient with history of echinococcus infection. We report an asymptomatic 60 year-old woman with history of echinococcal cyst in the liver which was resected approximately 20 years ago, developed a new liver cystic lesion approximately 7 years after resection. Contrast enhanc...

BACKGROUND An abdominoscrotal hydrocele (ASH) is a rare lesion and should be considered in the differential diagnosis of abdominal cystic lesions in boys. CASE REPORT We report a case of a 4-month-old boy with a thin-walled, anechoic cystic abdominal mass in ultrasound (US) examination. As the size of the lesion increased in follow-up US after one month, computed tomography (CT) was performed...

Fibroadenoma is the most common breast tumor in adolescent and young women. Fibroadenomas that consist of sclerosing adenosis, papillary apocrine metaplasia, epithelial calcifications, and/or cysts greater than 3 mm are considered as complex fibroadenoma. The relative risk of developing breast cancer in patients with complex fibroadenoma is increased, compared to women with noncomplex fibroaden...

Primary neoplasms in the psoas muscle including schwannoma and soft tissue sarcoma with secondary cystic degeneration are rare entities. They are difficult to distinguish from psoas abscess purely based on radiological findings. Malignant fibrous histiocytoma (MFH) in the retroperitoneum is an uncommon entity in contrast to liposarcoma and leiomyosarcoma. Psoas abscess is a common infection in ...

Lymphangioma is an abnormal collection of lymphatics that are developmentally isolated from the normal lymphatic system. Lymphangioma rarely presents as a solitary pulmonary lesion. We report a rare case of intrapulmonary cystic lymphangioma involving the upper lobe of the right lung, which presented with dyspnea in a 2-month-old infant. High-resolution computed tomography (HRCT) of the chest d...

Lymphangiomas are rare congenital benign tumors arising from the lymphatic system mostly encountered in the neck and axillary regions of pediatric patients. Pancreatic cystic lymphangiomas very rarely occur in adults. Radiologically, the lesion may mimic pancreatic carcinoma and should be considered in the differential diagnosis of any patient found to have an abdominal cystic mass. In this art...
