The novel influenza A H1N1 virus resulted in the recent influenza pandemic of 2009. In this article, we describe the spectrum of thoracic computed tomography (CT) findings in 8 patients with laboratory-confirmed H1N1 infection. Peribronchovascular and subpleural groundglass opacities and consolidations, pulmonary embolism, and pleural effusions are recently reported findings. Volume loss, bronchial wall thickening, bronchiectasis, mosaic attenuation, and lymphadenopathy are not commonly reported findings. Cryptogenic organizing pneumonia developed as a complication in one of our H1N1 cases, which has not been previously reported. We also describe radiologic-pathologic correlation in an additional case, where autopsy demonstrated diffuse alveolar damage.

Injuries to the brachial plexus typically result from road accidents and occur most commonly in young men involved in motorcycle accidents [1]. Brachial plexus injury is a rare entity, often resulting in lifelong motor and sensory dysfunctions. Moreover, lesions in the brachial plexus may lead to chronic pain [2]. Over the past several years diffusion-weighted imaging (DWI) has been widely applied to a variety of conditions, including infarcts, tumors, and demyelinating disease of the brain. DWI enables noninvasive characterization of biologic tissues based on their water diffusion properties. Diffusion-weighted images are obtained by acquiring T2-weighted images with the addition of a diffusion weighting gradient; the strength of the gradient is

We present a case of an 18 year-old woman with previous history of congenital cardiopathy, surgically treated in the infancy, referred for multidetector-row CT (MDCT) evaluation of chronic pelvic pain. Pelvic congestion syndrome caused by pelvic varicocele was demonstrated and multiple congenital anomalies (agenesis of the left common and external iliac artery, absence of the infrarenal vena cava, septate uterus and congenital spinal malformations including a thoracic butterfly vertebra, coccygeal agenesis and sacral hypoplasia) were incidentally discovered. To our knowledge, such a combination of congenital anomalies has not previously been documented in the literature.

Acquired gastric outlet obstruction (GOO) by a duodenal carcinoid is a very rare condition. We report an unusual case of 21 year old female who presented with epigastric fullness and postprandial upper abdominal distention of two and a half year duration and recurrent non bilious vomiting and progressive weight loss of two months duration. Confirmatory preoperative diagnosis was not available. The case was diagnosed as carcinoid postoperatively after pathologic examination. We are reporting this case because of its rarity and with excellent outcome if diagnosed and managed properly. Even on extensive search of medical literature we are not able to find report of such a lesion causing features of gastric outlet obstruction.

Macrodystrophia Lipomatosa is a rare disorder characterized by three-dimensional enlargement of one or more fingers or toes with predominantly fibro adipose tissue. Macrodystrophia Lipomatosa is usually diagnosed during childhood. In this case, we will discuss the radiological findings in the neglected case of a 45 year female with macrodystrophia lipomatosis.

Tumors derived from odontogenic tissues constitute an unusually diverse group of lesions. This multiformity reflects the complex nature of development of dental structures. There occurs a wide range of radiographic manifestations which may result from the fact that the jaw bones contain dental components of ectodermal and mesodermal origin enamel, dentin, cementum, and pulp tissues(1).Radiographs are foremost and the most important diagnostic techniques. In histopathologic techniques like decalcified sections, calcified structures such as enamel which are highly mineralized may be lost and thus only their empty spaces may remain. Computed Tomography (CT) provides very good spatial resolution i.e. the ability to distinguish between two separate structures that are very close together. Through this case report we highlight the use of CT technique along with a colour contrast software which uses in its principle, methods to quantify & qualitate the density to distinguish between enamel and dentin to provide an accurate diagnosis.

Objective: Identification of subsegmental pulmonary vessels is the basis for identifying subsegmental embolism. In the past studies have been performed to evaluate the depiction rate of spiral CT scanners. In this study the detection rate of subsegmental vessels using 64 MDCT (Sensation 64, Siemens, Germany) has been analyzed.Materials and Methods: Study population consisted of 55 consecutive patients with suspected pulmonary embolism. Standard acquisition parameters were applied using 1.2 mm collimation. An overall of 3127 segmental and subsegmental vessels was counted.Results: An overall depiction rate of 98% for the subsegmental vessels could be demonstrated.Conclusion: In times of increasing slice numbers and faster acquisition techniques, recent technical equipment allows better depiction of subsegmental pulmonary vessels. Anatomic regions of the subsegmental pulmonary vasculary that proved to be difficult to depict in the past can now be visualized more exactly.
