Calcific tendinitis: intramuscular and intraosseous migration.

Calcific tendinitis is a well-documented and extensively studied disease in the literature. Intramuscular and intraosseous migration are rare complications, which may present diagnostic challenges. This pictorial essay illustrates the imaging findings of these complications.

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.

Determination of the frequency of dyssynergic defecation and patient characteristics in patients with functional constipation.

Background/aims: Dyssynergic defecation, a subgroup of functional constipation, is a relatively new definition, diagnostic criteria of which have recently been described. Distribution of subgroups of functional constipation in our population is scarcely known. We aimed to evaluate the demographic characteristics and defecation features of patients as we determined the frequency of dyssynergic defecation in patients with functional constipation in our community.

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.

Power Doppler sonography: anything to add to BI-RADS US in solid breast masses?

Objective: To evaluate the contribution of power Doppler ultrasonography (PDUS) to breast imaging reporting and data system ultrasonography (BI-RADS US) categorization of solid breast masses.

Materials And Methods: Totally 94 solid lesions with histopathological results in 49 patients were included in the study. US features of the lesions were classified according to American College of Radiologists (ACR) BI-RADS US lexicon.

A variant of Poland syndrome associated with dextroposition.

Poland syndrome is characterized by partial or complete absence of pectoralis muscles, ipsilateral syndactyly, and occasionally other malformations of the anterior chest wall and breast. Other associated anomalies, including dextrocardia, renal malformations, and vertebral anomalies, have been reported in rare cases. The condition is more frequent among males, and usually occurs on the right hemithorax in the unilateral form.

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.

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.

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.

Effects of altitude on spleen volume: sonographic assessment.

Purpose: To use sonography to determine changes that may arise in splenic volume in humans from regions of lower altitude who begin to live in regions of higher altitude.

Materials And Methods: The study was conducted in the Turkish province of Ağri, at an altitude of 1750 m and included 108 healthy, nonsmoking, disease-free volunteers who had moved from regions at an altitude lower than 500 m. Length, width, and thickness of the spleen were measured using sonography.

Imaging of pulsatile tinnitus: a review of 74 patients.

Objective: Our aim was to assess the effectiveness of imaging modalities in detecting the underlying pathologies in patients with pulsatile tinnitus.

Materials And Methods: Seventy-four patients with pulsatile tinnitus were radiologically evaluated. All patients except two are evaluated on a thin-section bone algorithm computed tomography scan covering the temporal bone and skull base, 14 patients with or without contrast-enhanced brain computed tomography, 7 patients with magnetic resonance imaging and magnetic resonance angiography, 5 patients with digital subtraction angiography, and 12 patients with Doppler ultrasonography.

Gadolinium-enhanced 3D MR angiography of pulmonary hypoplasia and aplasia.

Objective: The goal of this study was to determine the role of gadolinium-enhanced 3D MR angiography (MRA) in patients with suspected pulmonary hypoplasia and aplasia in a retrospective analysis of MRA and digital subtraction angiography in 11 patients with clinical and/or radiologic suspicion of pulmonary hypoplasia and aplasia.

Conclusion: Gadolinium-enhanced 3D MRA is capable of diagnosing pulmonary hypoplasia and aplasia rapidly and accurately. Both pulmonary hypoplasia and aplasia can be shown morphologically in a noninvasive manner, obviating digital subtraction angiography.

Asymmetry of the height of the ethmoid roof in relationship to handedness.

The aim of this work was to study the handedness differences in the height of the right and left ethmoid roofs. Hand preference was assessed using the Edinburgh Handedness Inventory. The height of the right and left ethmoid roofs was measured with computerised tomography (CT).

Soft-tissue masses: use of a scoring system in differentiation of benign and malignant lesions.

The purpose of this study was to show the qualitative and quantitative MRI characteristics of soft-tissue masses in differentiation of benign and malignant lesions. A total of 90 soft-tissue lesions were reviewed in this study. The scoring system presents a more objective diagnostic performance in the prediction of benign or malignant masses.

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.

'Ecstasy'(MDMA)-induced pneumomediastinum and epidural pneumatosis.

Epidural pneumatosis and pneumomediastinum may occur after the inhalation of "Ecstasy" (methylenedioxymetamphetamine), but only one case has been reported in the literature. We report the case of a 21- year-old male patient who presented with epidural pneumatosis and pneumomediastinum. Chest CT demonstrated the pneumomediastinum and multiple air bubbles within the spinal canal.
