Dynamic Quantitative Imaging of the Masseter Muscles in Bruxism Patients with Myofascial Pain: Could It Be an Objective Biomarker?

We aimed to investigate whether the collaboration of shear wave elastosonography (SWE) and B-mode ultrasonography (US) could be offered as diagnostic tools to assess the presence, severity, and progress of bruxism, as well as a biomarker for the effectiveness of treatment in daily clinical practice. The study was designed as a quantitative evaluation of the masseter muscles (MMs) of the clinically diagnosed bruxism patients suffering from myofascial pain and MMs of the healthy individuals. Clinical examinations were made according to the diagnostic criteria for temporomandibular disorders (DC/TMD), and pain was assessed using a visual analog scale (VAS).

Symptomatic Bilateral Xanthogranuloma of the Choroid Plexus.

Xanthogranulomas (XGRs) of the choroid plexus are rare, asymptomatic, and benign lesions usually found incidentally. Here, we present a case of a 47-year-old male with bilateral XGR of the choroid plexus with periventricular edema and discuss our case in relation to a review of existing literature pertaining to the radiology of XGRs. To the best of our knowledge, this is the first reported case of bilateral trigonal XGR causing brain edema without ventricular dilatation.

Limbic Encephalitis Associated with Sjögren's Syndrome: Report of Three Cases.

Sjögren's syndrome (SS) may be complicated by neurological manifestations. We herein report three women (age range 26-60 years old) who all presented with limbic encephalitis (LE) as the predominant clinical feature 3 months to 15 years after the diagnosis of SS. The 26-year-old patient also developed acute motor axonal neuropathy one week after autoimmune encephalitis.

Cranial imaging findings in neurobrucellosis: results of Istanbul-3 study.

Objective: Neuroimaging abnormalities in central nervous system (CNS) brucellosis are not well documented. The purpose of this study was to evaluate the prevalence of imaging abnormalities in neurobrucellosis and to identify factors associated with leptomeningeal and basal enhancement, which frequently results in unfavorable outcomes.

Methods: Istanbul-3 study evaluated 263 adult patients with CNS brucellosis from 26 referral centers and reviewed their 242 magnetic resonance imaging (MRI) and 226 computerized tomography (CT) scans of the brain.

Obturator mononeuropathy due to adenocarcinoma of unknown primary origin.

A 35-year-old woman presented with a three-month history of left groin and thigh pain. Neurological examination and electromyography showed pathological features consistent with obturator nerve involvement. Imaging studies revealed a left retroperitoneal mass, which by pathological examination was shown to be metastatic adenocarcinoma of possible Mullerian origin.

Differentiation of benign from malignant cervical lymph nodes in patients with head and neck cancer using PET/CT imaging.

Purpose: To differentiate malignant from benign cervical lymph nodes in patients with head/neck cancer.

Methods: In this retrospective study, 39 patients with primary head/neck cancer who underwent Positron Emission Tomography (PET)/Computerized Tomography (CT) and image-guided lymph node biopsy were included.

Results: Overall, 23 (59%) patients had biopsy-proven malignant cervical lymphadenopathy.

The use of 18F-FDG PET ratios in the differential diagnosis of common malignant brain tumors.

Objective: This study examined the use of positron emission tomography (PET) ratios to improve the diagnostic ability of 18F-FDG PET/computed tomography (CT) in the differentiation of enhancing brain metastases, central nervous system lymphomas, and gliomas.

Materials And Methods: Seventy-six patients with malignant brain tumors and available magnetic resonance imaging and PET/CT examinations were included.

Results: Among standardized uptake value (SUV)-related parameters tested, tumor maximum SUV to ipsilateral cortex maximum SUV ratio (Tmax:WMimax) and maximum SUV (SUVmax) proved to be the two most valuable parameters for differential diagnosis.

Fecal tag CT colonography with a limited 2-day bowel preparation following incomplete colonoscopy.

Purpose: This study aimed to assess the feasibility and patient tolerance of a 2-day limited fecal tag bowel preparation in computed tomographic colonography (CTC) performed for incomplete conventional colonoscopy (CC) patients.

Materials And Methods: Seventy-five patients who underwent a CTC examination fbecause of incomplete CC were included. A low-residue diet was given for 2 days before CTC.

Comparison of a 4-Day versus 2-Day Low Fiber Diet Regimen in Barium Tagging CT Colonography in Incomplete Colonoscopy Patients.

Our aim was to compare the amount of residual feces, residual fluid, the tagging quality, and patient compliance using 4-day versus 2-day low fiber diet regimen in barium tagging CT colonography in incomplete colonoscopy patients. Methods. A total of 101 patients who underwent CT colonography were assigned to 2-day diet group (n = 56) and 4-day diet group (n = 45).

The efficacy of diffusion weighted imaging for detection of acute pancreatitis and comparison of subgroups according to Balthazar classification.

Background/aims: The aim of this study was to measure the apparent diffusion coefficient (ADC) values detected by diffusion-weighted imaging (DWI) in acute pancreatitis and compare them with computerized tomography (CT) findings in acute pancreatitis subgrouped by the Balthazar classification.

Materials And Methods: The study population included 50 patients diagnosed with clinical pancreatitis who were evaluated with both multidetector CT and magnetic resonance imaging (MRI) within 24 h of clinical presentation. We calculated pancreatic ADC values obtained from DWI (b=0 and b=1000 mm2/sn).

[Isolated hyoid bone fracture due to blunt trauma: case report].

Fractures of the hyoid bone are very rare. Diagnosis of hyoid fracture is difficult and can be made only with a strong degree of suspicion. We report a case of isolated hyoid bone fracture due to blunt trauma to the neck.

Topographic evaluation of the medial canthus-alar groove line in terms of determining the boundaries of lateral osteotomies.

Unlabelled: Nasolacrimal duct injury is a rare complication of rhinoplasty. Detailed regional anatomy knowledge is mandatory to avoid this complication. To display a reference line to protect the nasolacrimal duct from injury during lateral osteotomy, dacryocystography images of 10 patients who underwent rhinoplasty surgery at the authors' clinic were obtained.
