A variant of the median arcuate ligament syndrome: are sagittal images enough for diagnosis?

Median arcuate ligament syndrome (MALS), also known as celiac artery compression syndrome, is a rare cause of abdominal discomfort, postprandial pain and weight loss. Doppler ultrasonography (USG), computed tomography (CT), magnetic resonance imaging (MRI), and selective catheter angiography can be used to identify this abnormality. Classically, the "fish hook" appearance is seen on sagittal images.

Role of apparent diffusion coefficient values and diffusion-weighted magnetic resonance imaging in differentiation between benign and malignant thyroid nodules.

Objective: The purpose of the study was to differentiate between benign and malignant thyroid nodules using nodule-spinal cord signal intensity and nodule apparent diffusion coefficient (ADC) ratios on diffusion-weighted magnetic resonance imaging (DW-MRI).

Materials And Methods: Forty-four patients (27 females, 17 males; mean age, 49 years) with nodules who underwent DW-MRI were included in this study. The images were acquired with 0, 50, 400 and 1000 s/mm(2)b values.

Noncompaction of the myocardium coexistent with vertebral hemangiomas.

Arterial supply of the posterior interventricular sulcus: a CT coronary angiographic study.

Objective: The objective of this study was to determine the different vascularization patterns of the posterior interventricular sulcus (PIS) with coronary CT angiography.

Materials And Methods: Three hundred and fifty-six coronary CT angiograms (CCTA) were retrospectively analyzed in 248 men and 108 women (mean age, 54.9 years ± 13.

Sonographic appearances of the normal ulnar nerve in the cubital tunnel.

Purpose: To investigate the sonographic characteristics of the normal ulnar nerve in the cubital tunnel, as well as any differences related to age, sex, and dominant arm.

Method: Two hundred twelve elbows in healthy volunteers were evaluated sonographically. The cross-sectional area (CSA) of the ulnar nerve within the cubital tunnel was measured with the elbow in extension and in flexion.

MRI findings of intracranial tuberculomas.

Purpose: Tuberculosis involvement of the central nervous system continues to represent a serious problem, particularly in developing countries. The aim of this study was to characterize the magnetic resonance imaging (MRI) findings of intracranial tuberculoma, a form of neurotuberculosis.

Methods: We retrospectively reviewed the data of 27 patients with intracranial tuberculomas.

Split-cord malformation and accompanying anomalies.

Objective: To present the magnetic resonance imaging (MRI) appearances of spinal split-cord malformation (SCM) and to investigate the various types of congenital spinal disorders associated with SCM.

Materials And Methods: MR examinations of 23 patients with SCM were carried out in our hospital between June 2002 and May 2007 and retrospectively analysed.

Results: Nineteen (82.

Primary angiosarcoma of the spleen.

Primary angiosarcoma of the spleen is a rare neoplasm with a very poor prognosis. We present computed tomography and magnetic resonance imaging of a 49-year-old man with primary splenic angiosarcoma and liver metastasis. The literature on primary splenic angiosarcoma is reviewed and imaging variability of this rare tumor is discussed.

Multicentric malignant peripheral nerve sheath tumor.

We present a case of malignant peripheral nerve sheath tumor of multicentric origin, an extremely rare condition. A 25-year-old man was admitted to hospital with presenting symptoms of cough, dyspnea and left lateral back pain. Computed tomography and magnetic resonance imaging revealed extrapleural masses in the left hemithorax in addition to synchronous left inguinal mass.

Relationship between tuberculous otomastoiditis and tuberculous meningitis.

Objective: The aim of this study was to determine the correlation between tuberculous meningitis and tuberculous otomastoiditis.

Materials And Methods: Meningeal involvement sites were investigated by magnetic resonance imaging in 32 patients (21 males, 11 females) who had previously been diagnosed with tuberculous meningitis. Clinical and laboratory findings and responses to anti-tuberculous treatment were evaluated, and the presence of concomitant tuberculous otomastoiditis was also investigated.

The effect of pharyngeal soft tissue components on snoring.

Objective: To determine the effect of oropharyngeal air column area, parapharyngeal fat pad thickness, pterygoid muscle thickness, and parapharyngeal wall thickness on snoring.

Materials And Methods: Fifty-six individuals (35 men, 21 women) complaining of snoring in a questionnaire administered to patients attending the MR unit for cervical MR imaging were enrolled as the study group, and 39 (23 men, 16 women) individuals with no complaint of snoring were enrolled as the control group. Firstly, patients' body mass index (BMI) was determined.

Unilateral temporalis muscle hypertrophy with contralateral masseteric hypertrophy.

We report the MRI findings of a 22-year-old woman who complained of localized swelling in the left temporal region and right side of the face. MRI revealed left temporal and right masseter muscle hypertrophy, which to our knowledge has not been reported previously. The diagnosis of benign masticatory muscle hypertrophy was confirmed by biopsy.

Magnetic resonance imaging findings of adult-onset glutaric aciduria type I.

Glutaric aciduria or glutaric acidemia type I, an autosomal recessive disease, usually presents with an acute encephalopathic crisis in young children. We report the magnetic resonance (MR) and proton MR spectroscopy (MRS) imaging findings of a previously healthy 20-year-old man who presented with recurrent headaches. Organic acids from the patient's urine contained large amounts of adipate, glutarate, and 3-hydroxyglutarate consistent with glutaric aciduria type I.

Diagnostic value of CTE in patients with Crohn's disease.

Objective: The goal of our study was to compare the accuracy of computed tomography enteroclysis (CTE) to that of biopsy in detecting bowel wall alterations of the terminal ileum in Crohn's disease (CD).

Subjects And Methods: A total of 43 patients with either diagnosed or suspected CD (16 females, 28 males) underwent CTE and ileoscopy. Ileoscopy diagnosed 35 patients with CD of the ileum, while 8 patients served as the control group.

MRI appearance of retrocalcaneal bursitis and rheumatoid nodule in a patient with rheumatoid arthritis.

Rheumatoid arthritis is an autoimmune disorder of unknown etiology characterized by symmetric, erosive synovitis and sometimes multisystem involvement. Rheumatoid nodules have been reported in as many as 20-30% of patients with rheumatoid arthritis; however, they are not commonly seen in the feet. We present magnetic resonance (MR) findings of a rarely seen case of rheumatoid bursitis in the retrocalcaneal bursa associated with a subcutaneous rheumatoid nodule inferior to the calcaneus which histologically confirmed the rheumatoid arthritis.
