BACKGROUND: Due to the obstruction of the surrounding structures or stiff mucosa, the primary and recurrent nonexophytic nasopharyngeal carcinoma (NE-NPC) patients are difficult to be diagnosed histologically by traditional forceps biopsy. RESULTS: All the 15 cases had adequate biopsy for histological diagnosis. There were 5 cases of primary and 7 cases of recurrent NE-NPC, and 3 cases of inflammatory lesion. The histopathological diagnosis was consistent with the follow-up visit...

The pudendal nerve entrapment is an entity understudied by diagnosis imaging. Various causes are recognized in relation to difficult labors, rectal, perineal, urological and gynecological surgery, pelvic trauma fracture, bones tumors and compression by tumors or pelvic pseudotumors. Pudendal neuropathy should be clinically suspected, and confirmed by different methods such as electrofisiological testing: evoked potentials, terminal motor latency test and electromyogram, neuronal block and magnetic resonance imaging...

Fluid resuscitation following hemorrhagic shock is often problematic, with development of prolonged hypotension and edema. In addition, many trauma patients are also intoxicated, which generally worsens outcomes. We directly investigated how alcohol intoxication impacts hemorrhagic shock and resuscitation-induced microvascular leakage using a rat model with intravital microscopic imaging. We also tested the hypothesis that an endothelial barrier-protective bioactive lipid, sphingosine-1-phosphate (S1P), could ameliorate the microvascular leakage following alcohol intoxication plus hemorrhagic shock and resuscitation...

BACKGROUND: The Society of Vascular Surgery (SVS) guidelines currently suggest thoracic endovascular aortic repair (TEVAR) for grade II-IV and non-operative management (NOM) for grade I blunt traumatic aortic injury (BTAI). However, there is increasing evidence that grade II may also be observed safely. The purpose of this study was to compare the outcome of TEVAR and NOM for grade I-IV BTAI and determine if grade II can be safely observed with NOM. METHODS: The records of patients with BTAI from 2004 to 2015 at a Level I trauma center were retrospectively reviewed...

RATIONALE: Ectopic splenic autotransplantation refers to the heterotopic autotransplantation of splenic tissue and no treatment is necessary for it when patient is asymptomatic. Its incidence rate is reported up to 67% among patients with a history of splenic trauma and splenic surgery. The diagnosis of it before operation is really difficult, and it is easy to mimic as other tumors. PATIENT CONCERNS: We reported a 42-year-old man with hepatic splenosis, with history of splenectomy for traumatic splenic rupture 16 years ago and hepatitis B&C...

BACKGROUND: The Focused Assessment with Sonography in Trauma (FAST) protocol is considered beneficial in emergent evaluation of trauma patients with blunt or penetrating injury and has become integrated into the Advanced Trauma Life Support (ATLS) protocol. No guidelines exist as to the use of ultrasonography in trauma in Denmark. We aimed to determine the current use of ultrasonography for assessing trauma patients in Denmark. METHODS: We conducted a nation-wide cross-sectional investigation of ultrasonography usage in trauma care...

Pigmented villonodular synovitis (PVNS) is a rare proliferative disorder of the synovial membrane. This condition is usually monoarticular, can be locally destructive, and involves muscles, tendons, bursae, bones, and skin. The most commonly affected joints are the knee and hip, followed by the ankle and shoulder. Patients often present with pain, swelling, and joint effusion; however, the duration of symptoms varies. Total synovectomy is the preferred treatment for PVNS. Subtotal synovectomy is a factor of recurrence, and in diffuse PVNS, total excision is very difficult to achieve...

Tophi (plural of tophus, Latin for "stone") are stone-like deposits of monosodium urate in the soft tissues, synovial tissues, or in bones near the joints. They are pathognomonic for gout, the most common inflammatory arthritis in the United States, with an estimated lifetime prevalence of 4%. It is usually the end result of loss of the balance between uric acid production and excretion. It can be found anywhere in the body especially in areas of friction or trauma. It is usually painless and rarely to present as the initial manifestation of gout...

BACKGROUND: Persistent sciatic artery (PSA) is a rare congenital anomaly of the circulation of the lower limb that results from the persistence of an artery that normally regresses early in embryonic development. PSA is usually an incidental finding and is exceedingly rare to find bilaterally. CASE REPORT: We present the case of a rare presentation of PSA that resulted in a favorable outcome for a patient who sustained a gunshot wound to his midthigh and discuss the history, embryology, anatomy, classification schema, imaging evaluation, complications, diagnosis, and management of PSA...

BACKGROUND Sclerosing mesenteritis (SM) is a rare idiopathic inflammation and fibrosis of the mesentery. Its etiology and pathogenesis remain unclear. It has been linked to abdominal trauma related to peritoneal dialysis, recent abdominal surgery, idiopathic inflammatory disorder, paraneoplastic syndrome, ischemia/infection, and autoimmunity. Abdominal CT is the most sensitive imaging modality, and diagnosis is usually confirmed by surgical biopsy. Patients most often present with abdominal pain, nausea, vomiting, diarrhea, and weight loss, and less commonly with chylous ascites and small bowel obstruction...

The delayed development of splenic artery pseudoaneurysm (SAP) can complicate the nonoperative management of splenic injuries. We sought to determine the utility of repeat imaging in diagnosing SAP in patients managed nonoperatively without angioembolization. We hypothesized that a significant rate of SAPs would be found in this population on repeat imaging. Patients undergoing nonoperative splenic injury management from January 2011 to June 2015 were queried from the trauma registry. Rates of repeat imaging, angioembolization, readmission, and SAP development were analyzed...

The present report illustrates a very rare case report of a foreign body granuloma of the foot associated with a 2-year period of a retained spongeous rubber foreign body after a penetrating injury. Because it appeared almost 2 years after the injury, the history of trauma was minimized, the foreign body had migrated from the plantar to the dorsal side of the foot, and the radiographic appearance resembled a malignant process, it was difficult to rule out the possibility of a malignant tumor. This case shows the weakness of magnetic resonance imaging in detecting spongeous rubber in the body...

Posttraumatic stress disorder (PTSD) has been associated with altered resting-state functional connectivity (rs-FC) of several brain regions within the salience (SN) and default-mode (DMN) networks, including the hippocampus. However, most rs-FC studies have not focused primarily on the hippocampus, nor have they appreciated its structural heterogeneity, despite clear evidence for a dissociation between posterior and anterior hippocampal connectivity. Here, we examine rs-FC of anterior and posterior hippocampus with key regions in the SN (amygdala, insula, and dorsal anterior cingulate cortex/pre-supplementary motor area) and DMN (ventromedial prefrontal cortex, posterior cingulate cortex, and precuneus) previously implicated in PTSD, using a seed-based approach...

Familiarity with congenital heart disease (CHD) and its manifestations in adults is becoming increasingly important for the practicing cardiothoracic imager. The use of computed tomographic angiography is becoming commonplace not only in adults with a history and subsequent interventions for CHD as a child but also in de novo detection of-typically-milder, survivable forms of CHD, which are clinically suspected because of declining cardiac performance, cardiac events, or murmurs. Occasionally, adult CHD (ACHD) is found incidentally on scans performed for other indications (eg, trauma or neoplasm staging) because of improvements in computed tomographic technology and advanced visualization...

PURPOSE: Ocular imaging can enhance our understanding of wound healing. We report anterior segment optical coherence tomography (ASOCT) findings in penetrating corneal injury. METHODS: Serial ASOCT was performed after repair of penetrating corneal injury. Internal aberrations of wound edges were labeled as "steps" or "gaps" on ASOCT images. The wound type was characterized as: type 1: continuous inner wound edge or step height ≤ 80 µm; type 2: step height > 80 µm; type 3: gap between wound edges; and type 4: intraocular tissue adherent to wound...

Computed tomography (CT) imaging is increasingly used in emergency departments and trauma services and is being offered as a supplemental tool with autopsy in coroner's and medical examiner's offices throughout the United States. The availability of CT images in lieu of traditional X-rays for medicolegal autopsies may lead to misinterpretation of images for forensic pathologists who are not familiar with these types of images. Forensic pathologists must become familiar with CT imaging, the basis of CT image formation and how to interpret CT images appropriately...
