We investigated the radiologic-pathologic correlation of a strong hypointense rim on T2-weighted images (T2-hypo-rim) surrounding breast mass lesions and evaluated its clinical significance. We retrospectively reviewed 3503 consecutive breast magnetic resonance imaging (MRI) examinations. The T2-hypo-rim was defined as a border of strong hypointensity compared with the fat signal on fat-suppressed T2-weighted images. Detected lesions with T2-hypo-rim were classified as a solid or cystic mass with MRI and correlated with histopathologic findings...

The aim of the present paper is to report undiagnosed sporadic neurofibromatosis type 2 presenting with symptomatic compressive spinal tumors following pregnancy. A 36-year-old woman experienced progressive, severe lumbar radicular pain in the second trimester of pregnancy which became intractable soon after delivery. Magnetic resonance imaging revealed a complex heterogeneous hypointense mass lesion around the conus. There were two small punctate lesions in the cauda equina suggestive of myxopapillary ependymoma with 'drop metastases...

Arachnoid cysts are a relatively common finding in adult patients, especially with the advent of advanced imaging techniques. The overall incidence ranges from 1-2%, and the majority are clinically silent1,2 . Arachnoid cysts are postulated to arise by congenital anomalies or trauma1 . De novo formation of arachnoid cysts has been reported, but is exceptionally rare and mostly found in the pediatric population after head trauma3-5 . There have only been two reported cases of symptomatic de novo arachnoid cyst formation in adult patients to date, both with histories of head trauma6,7 ...

OBJECTIVES: Obesity is increasing in developed countries and is a risk factor for pancreatic cancer (PaC). We previously reported that obesity was associated with pancreatic cystic lesions (PCLs), which are both precursors of, and risk factors for, PaC. In the present study, we further investigated the relationship between visceral adiposity and adiponectin levels and the extent of PCLs. METHODS: Individuals who underwent comprehensive health screening at our institution between January 2008 and March 2013 were analyzed...

Male breast cancer is an uncommon disease that constitutes 1% of all breast cancers and encapsulated papillary carcinoma (EPC) is a rare subtype of malignant male diseases. Gynecomastia is the most common disease of the male breast. We report a 63-year-old male patient with EPC accompanied by gynecomastia that was diagnosed and treated at our breast center. Mammography showed an oval-shaped dense mass with circumscribed margins on the ground of nodular gynecomastia. On ultrasonographic exam, we saw a well-circumscribed complex mass with a solid component which was vascular on Doppler ultrasonography...

BACKGROUND: Birt-Hogg-Dubé syndrome (BHDS) is a recently recognized inherited multiple cystic lung disease causing recurrent pneumothoraces. Similarly to the lesions in patients with lymphangioleiomyomatosis (LAM), the pulmonary cysts are innumerable and widely dispersed and cannot all be removed. We recently described a total pleural covering (TPC) that covers the entire visceral pleura with oxidized regenerated cellulose (ORC) mesh. TPC successfully prevented the recurrence of pneumothorax in LAM patients...

RNASET2 deficiency in humans is associated with infant cystic leukoencephalopathy, which causes psychomotor impairment, spasticity, and epilepsy. A zebrafish mutant model suggests that loss of RNASET2 function leads to neurodegeneration due to the accumulation of non-degraded RNA in the lysosomes. The goal of this study was to characterize the first rodent model of RNASET2 deficiency. The brains of 3- and 12-month-old RNaseT2 knockout rats were studied using multiple magnetic resonance imaging modalities and behavioral tests...
