Osteoid Osteoma of Petrous Bone: A Rare Cause of SensorineuralDeafness

Osteoma of temporal bone is a rare benign neoplasm commonly arising from mastoid bone. Rarely, it may arise from petrous bone in cerebellopontine angle producing sensorineural hearing loss. This article describes computed tomography scan (CT scan) and magnetic resonance imaging (MRI) findings in a rare case of petrous bone osteoid osteoma producing ipsilateral sensorineural deafness.

Female SubFertility - An Imaging Insight

In this era of modern medicine, we are encountering more and more cases of male and female subfertility partly due to increasing health awareness and partly due to different pathology conditions. With advancements in the field of imaging, it is now possible to precisely diagnose multiple medical conditions responsible for subfertility. These imaging techniques may also play a pivotal role in guiding treatment and management of many of these conditions. Hence, this article focuses on utilizing an imaging armamentarium in cases of female sub fertility.

Post-Traumatic Fronto-Ethmoidal and Orbital Encephalocele â A RareEntity

In the present era of increasing road-traffic accidents, facial trauma of variable severity is being frequently encountered involving the orbits and sinuses. Post-traumatic, fronto-ethmoidal and orbital encephaloceles are rare entities requiring early intervention to prevent complications. Cross-sectional imaging by computed tomography and magnetic resonance imaging play a pivotal role in early detection of these entities. Hence in this article, we are describing a rare case of post-traumatic encephalocele with fronto-ethmoidal and orbital components with its clinical presentation which was diagnosed confidently by magnetic resonance imaging affecting the final management.

Imaging and Clinical Relevance of Intrahepatic Gall Bladder-A Rare Anomaly

Intrahepatic gall bladder (GB) is an uncommonly encountered condition in clinical practice characterised by ectopic location of GB within the hepatic parenchyma. This condition not only produces difficulty in clinical diagnosis of various GB diseases especially cholecystitis and carcinoma but also in their management including cholecystectomy. Hence, this article discusses imaging diagnosis as well as the clinical difficulties faced in patients with this rare anomaly.

Diffusion Tensor Tractography (DTT): An Objective Method of Determining Clinically-Relevant, Compressive, Spinal Cord Myelopathy

We commonly come across cases of compressive spinal cord myelopathy (CSCM) due to variety of clinical conditions in our day-to-day radiological practice. Magnetic resonance imaging (MRI) has long been considered as the gold-standard imaging tool for evaluation of such cases. These cases reveal signs of spinal cord compression with or without alteration in spinal cord parenchymal signal alteration. Though, diffusion tensor imaging especially fiber-tracking or tractography has been described to be superior to routine MRI in predicting prognosis and urgency of decompression yet fewer studies have been conducted to demonstrate it especially in developing world. Hence, this study aims to evaluate diffusion tensor tractography (DTT) as an advanced dimension of MRI in patients with CSCM in predicting necessity of decompression management, predicting prognosis and evaluating post-decompression outcome objectively in simplified manner. *Corresponding author: Dr. Rajul Rastogi, MD, ADND, MNAMS, FIMSA, FICRI, Department of Radiodiagnosis, Teerthanker Mahaveer Medical College and Research Center, Moradabad, U.P, India; E-mail: eesharastogi@gmail.com Received Date: August 26, 2016 Accepted Date: September 16, 2016 Published Date: September 23, 2016 Citation: Rastogi, R., et al.

MRI Diagnosis in Classical Metachromatic Leukodystrophy

Metachromatic leukodystrophy (MLD) is a rare group of genetically-transmitted, autosomal-recessive, lipid-storage disorders characterised by accumulation of glycosphingolipids caused by deficiency of Arylsulfatase-A enzyme in lysosomes of cells necessary for formation of normal myelin sheath. The disease can present anytime from infancy to adulthood and is characterised by progressive deterioration of motor & neurocognitive functions with variable prognosis. Though till date, there is no definitive treatment / cure for the disease yet bone marrow transplantation in infancy has shown to delay the progression of disease & gene therapy in animal experiments has shown promising future, making early diagnosis very imperative. Diagnosis is usually suspected on magnetic resonance imaging (MRI) of brain and confirmed by enzyme assays. Hence, in this article we are describing the classical brain MRI and clinical features to make the readers aware of this uncommon but important neurological entity. *Corresponding author: Dr. Rajul Rastogi, MD, ADND, MNAMS, FIMSA, FICRI, Department of Radiodiagnosis, Teerthanker Mahaveer Medical College and Research Center, Moradabad, U.P, India, E-mail: eesharastogi@gmail.com Received Date: November 14, 2016 Accepted Date: December 15, 2016 Published Date: December 20, 2016 Citation: Rastogi, R., et al.

CT or MRI Which is better for RectalCancer Imaging

Colorectal cancer is one of the common causes of cancer-related mortality with rectal cancer representing a significant proportion. Cross-sectional imaging techniques especially computed tomography (CT) and magnetic resonance imaging (MRI) play an important role in preoperative staging of rectal cancer. There has always been a debate about the single best imaging modality for staging of rectal cancer in order to achieve the best surgical outcome. Hence, this article focuses on the comparative role of CT & MRI in staging of rectal cancers.

Adenopathy and fibrosis in thoracic sarcoidosis occurring concurrently-A rare presentation

Sarcoidosis is a common multisystem disorder affecting the thoracic region. A well-defined, clinical staging system already exists for thoracic sarcoidosis. Rarely, combinations of signs / symptoms or imaging features may occur that may challenge the staging system as seen in our case and may force us to realize that our understanding of the disease pattern is still in the stage of evolution. In this article, we are describing a rare combination of adenopathy with pulmonary fibrosis (first and final stage features) in thoracic sarcoidosis at presentation.

Comparative Role of Sonourethrography (SUG) and Magnetic Resonance Urethrography (MRU) in Anterior Male Urethral Strictures

Anterior urethral stricture is a common clinical condition encountered in day-to-day urological practice affecting predominantly males. Retrograde urethrography (RGU) is a common investigation done to determine the future course of management. But with increasing use of plastic surgery and other endoscopic procedures, information regarding presence of spongiofibrosis and other associated conditions, in addition to length of stricture is being demanded from radiologist for deciding the mode of management. Sonourethrography (SUG) has started gaining acceptance over RGU in last few decades for determining periurethral spongiofibrosis which at the same time obviates radiation to gonads. In recent years, magnetic resonance urethrography (MRU) has also been advocated for evaluation of anterior urethral strictures due to its excellent soft tissue contrast and lack of operator dependence. Besides, MRU can delineate posterior urethra simultaneously, affecting further management obviating the need for micturating cystourethrogram (MCU). Hence, in this article we evaluate the comparative role of SUG ad MRU in the evaluation of male anterior urethral strictures.

Arteriovenous Fistula and Pseudoaneurysm: A Rare Complication of Central Venous Catheterization

Central venous catheterization (CVC) is a commonly performed invasive procedure in pre-operative period and for long-term intravenous access. Image-guided CVC has gained importance as it not only helps in reducing number of attempts but also prevents wrong internal jugular vein (IJV) punctures leading to reduced incidence & severity of CVC complications. Lack of availability of image-guidance related infrastructure and competence are responsible for non-image-guided CVC-related complications in developing countries. This article emphasizes the importance of image-guided CVC by discussing a case of arteriovenous fistula (AVF) between a small branch of external carotid artery and internal jugular vein detected in immediate postoperative period following CVC which was performed without image-guidance.
