(Aim) It is beneficial to classify brain images as healthy or pathological automatically, because 3D brain images can generate so much information that it is time consuming and tedious for manual analysis. Among various 3D brain imaging techniques, magnetic resonance (MR) imaging is the most suitable for brain, and it is now widely applied in hospitals, because it is helpful in the four ways of diagnosis, prognosis, pre-surgical, and postsurgical procedures. Although there are automatic detection methods, they suffer from low accuracy...

Facial nerve schwannoma is a rare intracranial tumor. Treatment for this benign tumor has been controversial. Here, we report a case of extracranial facial nerve schwannoma treated successfully by hypo-fractionated CyberKnife (Accuray, Sunnyvale, CA) radiosurgery and discuss the efficacy of this treatment. A 34-year-old female noticed a swelling in her right mastoid process. The lesion enlarged over a seven-month period, and she experienced facial spasm on the right side. She was diagnosed with a facial schwannoma via a magnetic resonance imaging (MRI) scan of the head and neck and was told to wait until the facial nerve palsy subsides...

BACKGROUND: Mitotically active cellular fibroma (MACF) of the ovary, characterized by relatively high mitotic activity without severe atypia, represents a relatively new disease entity. MACF is categorized as a benign ovarian tumor. However, due to a limited number of case reports, its clinical and pathological features and optimum management remains largely undetermined. Herein, we report on a rare case of MACF that grew rapidly in size and was diagnosed on detailed pathological examination...

BACKGROUND: -In patients with a dilated proximal ascending aorta and trileaflet aortic valve (TAV), we sought to assess a) factors independently associated with increased long-term mortality and b) the incremental prognostic utility of indexing aortic root to patient height. METHODS: -We studied consecutive patients with a dilated aortic root (≥4 cm) that underwent echocardiography and gated contrast-enhanced thoracic aortic computed tomography or magnetic resonance angiography between 2003-2007...

Audiologists can provide an effective and safe service through direct referral for magnetic resonance imaging screening in selected cases Direct audiology referral for magnetic resonance imaging reduces need for new ENT clinic appointments as well as reducing the inconvenience of repeated visits to hospital for patients Our experiences following the change of practice audit support the adoption of a more stream-lined audiology-led service Good practice areas that were highlighted should be emphasised: good two-way communication between audiology and ENT leads and the value of educational feedback from radiology This article is protected by copyright...

INTRODUCTION: The increasing use of endoscopic ultrasound-guided fine needle aspiration (EUS-FNA) cytology to examine pancreatic neoplasms has led to an increase in the diagnosis of metastases to the pancreas. Renal cell carcinoma (RCC) is the most common metastasis to the pancreas. Our study examines 33 cases of metastatic RCC to the pancreas sampled by EUS-FNA from four large tertiary care hospitals. MATERIALS AND METHODS: We searched the cytopathology database for RCC metastatic to the pancreas diagnosed by EUS-FNA from January 2005 to January 2015...

We report two cases of penile fracture. Case 1 was in a 22-year-old male. He heard a cracking sound during urination and experienced acute penile pain and detumescence. He was admitted to our hospital on that day. Case 2 was in a 52-year-old male. He heard a cracking sound during sexual intercourse and experienced detumescence. He was admitted to our hospital on the next day. In both cases, magnetic resonance imaging (MRI) showed disruption of the tunica albuginea. We performed immediate surgical repair through localized incision...

A 69-year-old man was referred to our hospital with the chief complaint of a painless right scrotal swelling gradually increasing in size during the past 10 years. Testicular tumor markers were within the normal range. Ultrasonography showed an intrascrotal homogeneous mass. Computed tomography and magnetic resonance imaging revealed an inguinal mass, which mainly consisted of fat signal area and partially well enhanced in vascular density. Pre-surgical diagnosis was liposarcoma of spermatic cord estimated by radiographic examination and resection of the right intrascrotal tumor with high inguinal orchitectomy was performed...

A 55-year-old woman was referred to our hospital with dysuria. We were unable to catheterize her using a nelaton catheter because of a urethral stricture, resulting in a large residual urine volume on ultrasonography. The circumference of the periurethral tissue was also thickened and the entire length of the urethra was stenotic, without apparent cause, on magnetic resonance imaging. Biopsy did not reveal malignancy. The pathological diagnosis of the periurethral tissue was simply fibrosis, and there was no definitive diagnosis...

BACKGROUND: Isolated hypothalamic-pituitary Langerhans cell histiocytosis (HPLCH) is very rare. We investigated the clinicopathological characteristics, endocrine function changes, BRAF(V600E) mutations and treatments of isolated HPLCH. METHODS: We identified seven patients with isolated HPLCH by reviewing the clinical and pathological files in our hospital from 2007 to 2015. The clinical characteristics of the seven patients were retrospectively reviewed, especially the endocrine function changes...

BACKGROUND: Sialodochitis fibrinosa is a rare disease which is characterized by recurring episodes of pain and swelling of the salivary glands due to the formation of mucofibrinous plugs. Analytic studies ascertain elevated levels of eosinophils and immunoglobulin E (IgE). Imaging studies such as magnetic resonance imaging (MRI) and sialography reveal dilation of the main salivary duct (duct ectasia). Treatment is initially supportive, consisting of compressive massages, and use of antihistamines and/or corticosteroids...

Intraparotid hemangioma of the children is a rare neoplasm, posing diagnostic dilemma to the diagnosticians as well as treating clinicians. A 2-month-old male infant presented with a diffuse swelling in the parotid region since birth that was gradually increasing in size. The ultrasonography (USG) report was suggestive of a right intraparotid mass of uncertain etiology; whereas magnetic resonance imaging (MRI) report inclined toward a mass associated with chronic inflammatory pathology. Fine-needle aspiration cytology (FNAC) suggested two differentials - a vascular neoplasm of the parotid gland and a spindle cell neoplasm with increased vascularity...

BACKGROUND: Acute transverse myelitis is uncommon and presumably results from an autoimmune process or a preceding infection. Most cases of bacterial myelitis are due to hematogenous dissemination from urinary or respiratory tract infections or contiguous spreading from a neighboring infected structure. A psoas abscess rarely spreads to higher levels of the spinal cord. No cases of acute cervical myelitis due to a psoas abscess have been previously reported. CASE PRESENTATION: A 34-year-old man was transferred to our hospital due to progressive muscle weakness, sensory deficits and severe hypotension...

Idiopathic osteonecrosis of the femoral head (ONFH) can be correctly diagnosed in accordance with the established criteria. However, some general orthopedic physicians have misdiagnosed patients as having ONFH. The goal of this study was to clarify the radiologic and clinical features of misdiagnosed patients. This study included 50 patients who were referred to the authors' hospital by general physicians with a diagnosis of ONFH. The correct diagnosis was made based on the Japanese Investigation Committee diagnostic criteria for ONFH...

OBJECTIVE: The aims of this study were to describe pediatric emergency department (ED) referrals from urgent care centers and to determine the percentage of referrals considered essential and serious. METHODS: A prospective study was conducted between April 2013 and April 2015 on patients younger than 21 years referred directly to an ED in central Pennsylvania from surrounding urgent care centers. Referrals were considered essential or serious based on investigations/procedures performed or medications/consultations received in the ED...
