Desmoid type fibromatosis is an uncommon benign disease entity of which its etiology currently unknown. It constitutes 0.3% all solid neoplasms, but it rarely seen in the breast and even more scarcely reported to develop association with implant. We present ultrasonography magnetic resonance imaging findings a 29-year-old female patient after implant surgery. Knowledge associated will be helpful for accurate diagnosis appropriate management.

Proliferating trichilemmal tumor (PTT) is a rare that originates from the outer root sheath of hair follicle. About 90% PTTs occur on scalp. The sonographic findings PTT in subungual region have not been reported previously. In our case, sonography showed heterogeneous mass containing echogenic foci with no detectable intratumoral vascularity. These probably represent keratin and cholesterol. © 2017 Wiley Periodicals, Inc. J Clin Ultrasound 46:215-217, 2018.

Abstract Eccrine spiradenoma is a rare, benign, adnexal skin tumor of the sweat gland, which may manifest in any part body. It typically located dermal or subcutaneous fat layer. spiradenomas rarely progress to malignant transformation and only few cases have been reported. Due its rarity, there reports about sonographic appearances eccrine spiradenoma. We report findings one case spiradenoma, deep layers upper arm middle‐aged woman.

Chlorfenapyr is widely used as an insecticide, despite it being fatal to humans. However, chlorfenapyr-induced central nervous system toxicity has rarely been reported. We report the magnetic resonance imaging (MRI) findings in a rare case of toxic leukoencephalopathy. A 71-year-old man who had ingested chlorfenapyr approximately two weeks prior visited our hospital and presented with bilateral lower motor weakness voiding dysfunction that developed days before admission. Brain MRI revealed...

This study investigated the performances of precipitable water vapor (PWV) retrieval from sets ground global positioning system (GPS) signals, each which had different length observing-session duration, for purpose obtaining as short session duration possible that is required at least appropriate PWV meteorological usage. The shorter highly desirable to make most use GPS instrument on board mobile observation vehicle making measurements place by place. First, using Bernese 5.0 software was...

To investigate gray-scale and color Doppler sonographic (US) features of complex fibroadenoma (FA), according to the Breast Imaging-Reporting Data System (BI-RADS) lexicon.From 2010 through 2013, 586 women with FAs were seen; 101 (17%) those lesions diagnosed as on percutaneous needle biopsy or surgery. Among patients FAs, 67 who had US examination results available included in this study. In addition, from 98 simple controls. retrospectively analyzed by two breast radiologists consensus for...

Objective The aim of the study was to compare diagnostic performance model-based iterative reconstruction (MBIR), adaptive statistical (ASIR), and filtered back projection (FBP) on submillisievert low-dose computed tomography (LDCT) for detecting hepatic metastases. Methods Thirty-eight patients having metastases underwent abdomen CT. Computed protocol consisted routine standard-dose portal venous phase scan (120 kVp) 90-second delayed (80 kVp). LDCT images were reconstructed with FBP, ASIR,...

Metastasis to the thyroid is very rare in hepatocellular carcinoma (HCC) and only a few cases have been reported. Herein, we report case of metastatic HCC 63-year-old man discuss various radiologic findings. Computed tomography (CT) revealed heterogeneous enhancing mass that had invaded cartilage left upper thyroid, compressing airway. Ultrasonography (US) showed hypoechoic with increased vascularity peripheral portion. The focal intense uptake on positron emission tomography-computed...

Background: Cardiocerebral infarction (CCI) is the simultaneous occurrence of acute ischemic stroke (AIS) and myocardial (MI) at same time (synchronous), or one after another (metachronous). This study aimed to investigate differences in underlying mechanisms between synchronous metachronous CCI. Methods: analyzed patients with AIS registered Clinical Research Collaboration for Stroke Korea Prospective Registry a single Center from January 2019 December 2022. Patients CCI (MI within 72 hours...

Klüver-Bucy syndrome may result from affection of various location brain. We report a case associated with isolated bilateral hippocampal atrophy without any abnormal lesion in other areas following status epilepticus. A 31-year-old man who had no significant medical history presented epilepticus after encephalitis unknown etiology. He been recovered three weeks later, but afterwards he developed syndrome: hyperphagia, hypersexuality, hypermetamorphosis, anterograde amnesia and dysosmia....

Background As urinary stone diseases are common in young adults and have a high recurrence rate, repetitive computed tomography (CT) scans would increase the radiation hazard. Therefore, CT dose reduction is needed diagnosis of stones. Purpose To prospectively evaluate added value adaptive statistical iterative reconstruction (ASIR) applied to half-dose (HDCT) quarter regular non-enhanced (QDCT) for detection Material Methods One hundred twelve consecutive patients who presented with acute...

Primary sarcomas of the great vessels are extremely uncommon tumors, with aortic sarcoma being rarest type. They tend to occur in thoracic aorta, followed by abdominal aorta and thoracoabdominal aorta. have a propensity for metastases they cause acute arterial embolism (1). Undifferentiated pleomorphic sarcoma, also called malignant fibrous histiocytoma, has been defined as group pleomorphic, high-grade that fail show any line differentiation using currently available ancillary techniques...

Artificial Neurons An artificial tactile neuron based on an ovonic threshold switch and a piezoresistive sensor reported by Suyoun Lee, Hyunjung Yi, co-workers in article number 2201608 can encode the elastic stiffness of pressed materials into spike-frequency evolution patterns. The spiking representation combination with spiking-neural-network-based learning be used to classify malignant status breast tumors low energy consumption, latency, yet high accuracy.
