BACKGROUND: Anatomical imaging findings indicating normal bowel rotation can be identified on cross-sectional imaging, including magnetic resonance imaging (MRI) performed for non-related indications. OBJECTIVE: The goal of our study was to assess whether non-targeted MRI can accurately assess intestinal malrotation. MATERIALS AND METHODS: Four anatomical landmarks were assessed on MRIs of the chest, spine or abdomen performed from January 2006 to June 2014, on patients who also had upper gastrointestinal series (UGI) performed within 10 years of the MRI date: 1) retroperitoneal duodenum, 2) left upper quadrant duodenojejunal junction, 3) superior mesenteric artery to the left of the superior mesenteric vein, and 4) right lower quadrant cecum...

The most commonly employed radiologic method in diagnosis of pleural diseases is conventional chest radiograph. The commonest chest- X-Ray findings are the presence of pleural effusion and thickening. Small pleural effusions are not readily identified on posteroanterior chest radiograph. However, lateral decubitus chest radiograph and chest ultrasonography may show small pleural effusions. These are more efficient methods than posteroanterior chest radiograph in the erect position for demonstrating small amounts of free pleural effusions...

The clinical evaluation of patients with an anomalous aortic origin of a coronary artery (AAOCA), a congenital abnormality of the origin or course of a coronary artery that arises from the aorta, is challenging given its first presentation being sudden cardiac arrest in about half of the patients. Symptoms of chest pain, shortness of breath and syncope during exertion should be of concern in evaluating young athletes and nonathletes. The lack of abnormal signs on the physical exam and electrocardiogram further adds to the difficulty in establishing the diagnosis...

This 52-year-old male ex-smoker presented with a six-month history of progressive breathlessness and weight loss. He deteriorated acutely, and was admitted with severe type 1 respiratory failure. Apart from diffuse coarse crackles on chest auscultation, physical examination was unremarkable. High-resolution computed tomography (HRCT) showed diffuse cystic changes throughout the lungs. A diagnosis of pulmonary Langerhans cell histiocytosis (PLCH) was considered. Further workup identified a coincidental pancreatic lesion of uncertain significance, which remained indeterminate on magnetic resonance imaging (MRI) and on positron emission tomography (PET)...

OBJECTIVES: Magnetic resonance imaging (MRI) of the chest has long suffered from its sensitivity to respiratory and cardiac motion with an intrinsically low signal to noise ratio and a limited spatial resolution. The purpose of this study was to perform chest MRI under an adapted non invasive pulsatile flow ventilation system (high frequency percussive ventilation, HFPV®) allowing breath hold durations 10 to 15 times longer than other existing systems. METHODS: One volunteer and one patient known for a thymic lesion underwent a chest MRI under ventilation percussion technique (VP-MR)...

BACKGROUND: Congenital scoliosis is one of the 'difficult to treat' scenarios which a spine surgeon has to face. Multiple factors including the age of child at presentation, no definite pattern of deformity and associated anomalies hinder the execution of the ideal treatment plan. All patients of congenital scoliosis need to be investigated in detail. X rays and MRI of spine is usually ordered first. Screening investigations to rule out VACTERL (Visceral, Anorectal, Cardiac, Tracheo-esophageal fistula, Renal and Lung) abnormalities are required...

BACKGROUND: Respective proportions of final etiologies are disparate in cohorts of cardiac arrest patients, depending on examined population and diagnostic algorithms. In particular, prevalence and characteristics of sudden unexplained death syndrome (SUDS) are debated. We aimed at describing etiologies in a large cohort of aborted out-of-hospital cardiac arrest (OHCA) patients, in order to assess prevalence and outcome of SUDS. PATIENTS AND METHODS: We analyzed data from our prospective registry of successfully resuscitated OHCA patients admitted to a cardiac arrest centre between January 2002 and December 2014...

We report a case of solitary fibrous tumor (SFT) originating from the visceral pleura, which presented an extrapleural sign on chest computed tomography (CT) and magnetic resonance imaging (MRI). A 44-year-old woman presented at our hospital for a growing mass visible in chest X-rays. Chest CT and MRI detected a 27×12 mm lesion on the intrathoracic side of the right 3rd intercostal space. The extrapleural signs strongly suggested the tumor to be chest wall origin. However, the tumor was found to be pedunculate with an umbrella-like appearance locating on the visceral pleura of the lung...

Schwannoma is a benign tumor derived from Schwann cells that cover myelinated nerve fibers (1). Among primary bone tumors, intraosseous schwannoma accounts for less than 0.2% (2). We are reporting a rare case of an 18-year-old female presented with swelling in the posterior right thigh. The patient was asymptomatic and this was incidentally discovered by her massage therapist. However, the swelling was gradually growing since then. The plain radiograph findings were suggestive of a benign bone tumor. MRI with gadolinium was performed for further evaluation but it demonstrated suspicious features as evidenced by the extra osseous enhancing soft tissue component...

BACKGROUND: Retromolar trigone squamous cell carcinoma is relatively uncommon and due to its complex anatomy has always remained a challenge in terms of loco-regional control and survival. Surgery, radiotherapy, and chemotherapy as combined modalities have been used but high recurrence rates result in poor outcome. METHODS: We have retrospectively evaluated records of 62 patients treated in Head and Neck Oncology unit of Shaukat Khanum Memorial Cancer Hospital and Research Centre (SKMCH and RC), Lahore, Pakistan from 2004 to 2014 who were included based on the criteria of histopathological proven squamous cell carcinoma of retromolar trigone (RMT) treated with radical intent...

INTRODUCTION: Chest desmoid tumors (CDT) are rare lesions characterized by fibroblastic proliferation from the connective tissue. Although CDT have been studied previously, no cases following subfascial transaxillary breast augmentation (TBA) have been described. PRESENTATION OF CASE: The authors describe a case of CDT in a 28-year-old woman one year after TBA, which presented as a painful and progressive mass in the lower-inner right breast quadrant. MRI showed a soft-tissue tumor (6×3×4cm) that affected the region of the right anterior costal margin, without signs of structural costal invasion...

Sickle cell disease (SCD) is a life-threatening genetic condition. Patients suffer from chronic systemic and cerebral vascular disease that leads to early and cumulative neurological damage. Few studies have quantified the effects of this disease on brain morphometry and even fewer efforts have been devoted to older patients despite the progressive nature of the disease. This study quantifies global and regional brain volumes in adolescent and young adult patients with SCD and racially matched controls with the aim of distinguishing between age related changes associated with normal brain maturation and damage from sickle cell disease...

Spinal epidural arachnoid cyst (SEAC) is a benign condition whose pathophysiology is still uncertain. It is most commonly asymptomatic but it can cause severe neurological sequelae especially when treatment is not received in time. We conducted a retrospective study of three patients treated for SEAC conducted in the Neurosurgery Department, Hassan II University Hospital, Fez. We report the case of two male patients and a woman, with an average age of 35 years (range: 16-56 years), admitted with slow progressive spinal cord compression...
