BACKGROUND: Abnormalities in the maxillary sinuses are occasional findings on routine CT scans of the head. AIM: To study the incidental findings in the CT scans of the maxillary sinuses in patients with indications other than sinuses-related diseases. SETTING: Jos University Teaching Hospital, Jos, Nigeria. MATERIALS AND METHODS: Images of patients who underwent CT scan of the head over a 5-month period (January 2015- May 2015) were retrospectively reviewed with the exclusion of those whose indication for the scan was trauma or sinus related disease...

Gastrointestinal stromal tumors (GISTs) are the most common mesenchymal neoplasms of the gastrointestinal tract, and are characterized by a broad spectrum of clinical, histological and molecular features at presentation. Although focal and scattered calcifications are not uncommon within the primary tumor mass, heavy calcification within a GIST is rarely described in the literature and the clinical-biological meaning of this feature remains unclear. Cases with such an atypical presentation are challenging and may be associated with diagnostic pitfalls...

PURPOSE: Cone-Beam Computed Tomography (CBCT) is an important 3D imaging technology for orthopedic, trauma, radiotherapy guidance, angiography, and dental applications. The major limitation of CBCT is the poor image quality due to scattered radiation, truncation, and patient movement. In this work, we propose to incorporate information from a co-registered Red-Green-Blue-Depth (RGBD) sensor attached near the detector plane of the C-arm to improve the reconstruction quality, as well as correcting for undesired rigid patient movement...

INTRODUCTION: The modified Stoppa approach for acetabular fractures has become popular. However, the possibility of injury to the obturator nerve with this approach has not been sufficiently considered. We have experienced a case of nerve entrapment in severely displaced fractures. Therefore we performed a retrospective study to: 1) evaluate the incidence of obturator nerve injury in the modified Stoppa approach for acetabular fractures, 2) analyze the relationship between the extent of displacement of the quadrilateral plate and injury to the obturator nerve HYPOTHESIS: We hypothesized that obturator nerve injury would be related to a marked medial displacement of the quadrilateral plate PATIENTS AND METHODS: We conducted a retrospective cohort study of 22 patients with acetabular fractures that were surgically treated with the modified Stoppa approach...

Tazo Inui, David Frankel
OBJECTIVE: Renal arteriovenous malformation (AVM) is a very rare phenomenon (fewer than 200 cases in the literature), most commonly (75%) presenting with hematuria in young women. Renal AVMs may be cirsoid (multi-branched) or cavernous, with cirsoid morphology predominating 3:1. The historical treatment is partial nephrectomy. Best endovascular therapy is divided among many options. We present 2 cases of large renal AVMs treated with single Amplatzer plugs. METHODS: During a 2-year period (2014-15), 2 patients presented for vascular evaluation of renal AVMs found incidentally on workup for non-specific abdominal and back pain...

BACKGROUND AND PURPOSE: Perfusion abnormalities have not been well described in children with subdural hemorrhage (SDH). We investigated whether patients with abusive head trauma (AHT+) had more perfusion abnormalities than those without (AHT-). MATERIALS AND METHODS: We reviewed the perfusion MR studies of 12 infants with SDH and 21 controls. The perfusion images were obtained using a pseudo-continuous arterial spin-labeling sequence with volumetric fast spin-echo readout...

BACKGROUND: Early identification of patients with pelvic fractures at risk for severe bleeding requiring intervention is critical. We performed a multi-institutional study to test our hypothesis that pelvic fracture patterns predict the need for a pelvic hemorrhage control intervention. METHODS: This prospective, observational multi-center study enrolled patients with pelvic fracture due to blunt trauma. Inclusion criteria included shock on admission (SBP<90 or HR>120 and base deficit > 5, and the ability to review pelvic imaging...

Early identification of non-accidental trauma (NAT) is a critical component of pediatric trauma care. Literature searches were conducted related to the association of NAT with seven key areas: history, exam findings (burns, oral trauma, bruising) and imaging (fractures, abdominal and brain injuries). When available, odds ratios (OR) with 95% confidence intervals (CI) for associations with NAT are presented. Systematic reviews have been published in six of the seven key areas and are described. The operational definition of NAT was widely variable across studies, prohibiting meta-analysis...

Pulmonary artery pseudoaneurysms (PAPs) are uncommon but potentially lethal. They may be incidentally discovered on imaging, or following massive hemoptysis if they rupture, with high risk of mortality. The most frequent causes of PAP are trauma and infectious disease. Vasculitis, in particular Behçet's disease, neoplasm, congenital disease and pulmonary hypertension are rarer causes of PAP. A PAP can be suspected from chest X-Ray and contrast CT, but requires confirmation by CT angiography. Arteriography is no longer performed for diagnostic purposes, but can be useful to prepare endovascular occlusion of the PAP...

INTRODUCTION: Posttraumatic osteomyelitis (PTO) is a feared complication after surgical fracture care. Late diagnosis can result in interrupted and prolonged rehabilitation programmes, inability to work, medical dependency, unnecessary hospital admissions, and high medical and non-medical costs. Primary aim of this study was to assess preferred diagnostic imaging strategies for diagnosing PTO amongst orthopaedic and trauma surgeons, radiologists, and nuclear medicine physicians. Secondary aims were to determine the preferred serum inflammatory marker for diagnosing PTO and the existence of a local hospital protocol to diagnose and manage PTO...

Pseudoaneurysms of the cervical internal carotid artery are rare and usually result from trauma, infection, or rarely spontaneously. They harbor potential risk of life-threatening hemorrhage and warrant immediate management. Endovascular treatment in the form of stent placement and coiling is a well established technique for dealing with both intracranial and extracranial pseudoaneurysms. We present a case of a child who presented with fever, neck swelling, dysphagia, and respiratory distress in emergency for which clinical diagnosis of a neck abscess was made...

OBJECTIVE: There has been an increasing movement worldwide to create systematic screening and management procedures for atypical injury patterns in children with the hope of better detecting and evaluating nonaccidental trauma (NAT). A legitimate concern for any hospital considering implementation of a systematic evaluation process is the impact on already burdened hospital resources. We hypothesized that implementation of a guideline that uses red flags related to history, physical, or radiologic findings to trigger a standardized NAT evaluation of patients <4 years would not negatively affect resource utilization at our level II pediatric trauma center...

BACKGROUND: In total hip arthroplasty (THA), the acetabular cup and femoral stem must be correctly sized and positioned to avoid intraoperative and postoperative complications, achieve good functional outcomes and ensure long-term survival. Current two-dimensional (2D) techniques do not provide sufficient accuracy, while low-dose biplanar X-rays (EOS) had not been assessed in this indication. Therefore we performed a case-control study to: 1) evaluate the prediction of stem and cup size for a new 3D planning technique (stereoradiographic imaging plus 3D modeling) in comparison to 2D templating on film radiographs and 2) evaluate the accuracy and reproducibility of this 3D technique for preoperative THA planning...

We sought to assess the rate of CTA-diagnosed vertebral artery injury in patients with isolated transverse process fractures, with and without extension into the transverse foramen, in the blunt-trauma population served by our hospital. We queried our universities trauma registry between January 2009 and July 2014 for ICD-9 codes pertaining to cervical spine fractures. Of 330 patients identified, 45 patients had fractures limited to the transverse process and were selected for the study population. For each patient identified, demographics, injury mechanism, imaging reports, angiography findings, and treatments were recorded...
