Acute arterial tumor embolism is a rare complication in cancer patients. Most of the previously reported cases of arterial tumor embolism have been associated with pulmonary malignancies and occurred during the intraoperative and postoperative periods. Very few cases occurred spontaneously. To our knowledge, there is no previous report of spontaneous and massive tumor embolism occluding the abdominal aorta in patients suffering from primary pulmonary carcinoma. We describe the case of 64-year-old man who presented with left homonymous hemianopsia and backache...

Lemierre syndrome is an uncommon condition in which internal jugular vein thrombosis presents after recent oropharyngeal infection. Frequently, this is accompanied by septic emboli. This report outlines a variant of this disease process, with septic thrombophlebitis of the neck associated with a necrotizing skin infection of the lower lip and chin. A 25-year-old man with lower lip and chin swelling, initially managed with intravenous antibiotics, progressed to the development of a left facial vein thrombus, septic emboli to the lungs, and a necrotizing lower lip and chin infection that was managed with debridement, thrombectomy, and prolonged hemodynamic and pulmonary support...

Lemierre's syndrome is a rare and feared complication of pharyngitis, occurring most commonly in adolescents and young adults. It is typically defined by the constellation of septic internal jugular vein thrombophlebitis, pulmonary and other septic emboli, and sterilesite infection by Fusobacterium necrophorum. The rarity and severity of Lemierre's syndrome has made it an attractive subject for case reports but there is a paucity of evidence to inform areas of persistent uncertainty. In recent years, heightened attention and controversy has focused upon speculation that a purported rise in the incidence of Lemierre's syndrome is due to reduced antibiotic prescribing for respiratory tract infections, that F...

INTRODUCTION: Major surgery in the past 14 days is a relative contraindication to treatment of acute stroke with intravenous (IV) alteplase. The 2016 American Heart Association/American Stroke Association scientific statement discussing inclusion and exclusion criteria for alteplase in acute stroke allows for provider judgment citing a lack of evidence to support surgery as an absolute contraindication. CASE REPORT: A 59-year-old woman presented with acute left hemiparesis, dysarthria, and acute respiratory failure...

BACKGROUND Mucinous ovarian adenocarcinoma is one of the less common epithelial cancers of the ovaries, and typically does not occur in younger women. Nearly all mucinous ovarian adenocarcinomas present with early-stage disease without significant sequelae of cancer, such as clotting. Anchoring bias is a common problem in medicine that has been shown to significantly affect physician decision-making. CASE REPORT We present the case of a 24-year-old healthy female Chinese immigrant with no significant past medical history, who presented with a subacute history of nonproductive cough and shortness of breath with exertion...

Arteriovenous fistulas can lead to a number of different chronic complications. We describe a case where a patient developed a thrombosis within her brachiobasilic arteriovenous fistula, which was manually manipulated in order to restore fistula flow. This resulted in a pulseless electrical activity cardiac arrest within a few minutes. After ten minutes of chest compressions and intubation, there was return of spontaneous circulation. No epinephrine was given nor shocks administered. Patient was extubated within minutes and was alert, orientated and haemodynamically stable...

Aortoenteric fistulas (AEF) are a rare but life-threatening cause of gastrointestinal (GI) bleeding. We present the case of a primary AEF caused by ingestion of a toothpick by a 47-year-old male. This is the 10th known case in the literature in which a foreign body was found to be the cause of a communication between the aorta and the GI tract. Most foreign objects have been sewing needles; this is the first known case of a toothpick penetration. The patient presented to our institution with polymicrobial sepsis and bilateral pulmonary septic emboli...

BACKGROUND Air embolism into the systemic arterial circulation secondary to pulmonary barotrauma has rarely been reported. Herein, we report the clinical course of an extremely rare presentation of cerebral air embolism likely due to ruptured pulmonary bullae during commercial air travel. CASE REPORT A 65-year-old man suddenly became unconscious during an airplane descent. Upon landing, he was immediately transferred to the nearest emergency department where he was intubated for airway protection. His head CT angiogram showed multiple air pockets in the right parietal lobe suspicious for multiple air emboli...

REVIEW
Omar Bari, Philip R Cohen
Hereditary hemorrhagic telangiectasia (HHT) is an autosomal dominant condition with a prevalence of ~1 in 5,000 individuals. The pathophysiology of this condition centers on the lack of capillary beds between arterioles and venules, leading to direct contact between these vessels. This results in telangiectases on characteristic locations such as the face, fingers, mouth, and nasal mucosa. Visceral arteriovenous malformations (AVMs) are also observed in many patients, and these are most commonly seen in the brain, gastrointestinal tract, and lungs...

OBJECTIVE: Metastatic disease in melanoma has an unpredictable nature with deposits in rare locations such as musculature. Dual energy CT (DECT) provides high contrast-visualization of enhancement by using spectral properties of iodine. Purpose of this study was to evaluate whether iodine maps from DECT improve lesion detection in staging examinations of melanoma patients. METHODS: This retrospective study was approved by IRB and written informed consent was obtained from all patients...

An 18-year-old gentleman with a history of recurrent tonsillitis presented to the emergency room complaining of worsening sore throat. He was found to have a peritonisillar abscess, and imaging revealed a non-occlusive left internal jugular vein thrombosis. Lemierre's syndrome is a rare, potentially fatal condition characterized by internal jugular vein thrombosis with septicemia following an acute oropharyngeal infection. While anticoagulation is the mainstay of treatment of deep venous thromboembolism (DVT) and pulmonary embolism (PE), the use of therapy is controversial in septic thrombophlebitis...

We report a unique case of recurrent thromboembolism and its histological findings that were revealed in an autopsy. Although it is well known that repeating thrombosis presents organization and recanalization, we also observed rare findings of thickening of the bronchial artery and fixation of the valve of the lower extremity vein in this case.

OBJECTIVES: To identify the positive rate and negative predictive value (NPV) of our ventilation/perfusion (V/Q) single-photon emission computed tomography (SPECT) service as respective markers of overcalling (false positives) and undercalling (false negatives). We also identified the indeterminate rate as an indicator of the technical quality of the scans and reporter confidence. PATIENTS AND METHODS: V/Q SPECT studies carried out over 5 years were classified into positive, negative and indeterminate results...

Upper and lower extremity deep venous thrombosis (DVT) is defined as a blood clot within the deep veins of the affected extremities. These blood clots can either occur spontaneously or be associated with specific risk factors. Regardless of the cause, DVT is associated with significant morbidity and mortality and has the potential for lethal complications. The most notable complication is the potential for development of pulmonary embolism from a lower extremity DVT. As studies have reported, more than 90% of acute pulmonary emboli arise from the proximal veins...

PURPOSE: Fat emboli syndrome is a rare but well-described complication of long-bone fractures classically characterised by a triad of respiratory failure, mental status changes and petechial rash. In this paper, we present the case of a patient who sustained bilateral femoral fractures and subsequently developed FES. Our aim was to review and summarise the current literature regarding the pathophysiology and management of fat emboli syndrome (FES) and propose an algorithm for treating patients with bilateral femoral fractures to reduce the risk of FES...

RATIONALE: Death following orthopedic surgery has become rare, but does occur. Acute myocardial infarction (AMI) can be a cause of such death, but diagnosis of AMI is often challenging, even by autopsy. PATIENT CONCERNS: We have recently experienced 2 cases of sudden death after bone fracture surgery, in which AMI and pulmonary thromboembolism were clinically suspected as causes of death. Case 1 was a 60-year-old male with a history of diabetes mellitus who died 7 days after surgery for Lisfranc dislocation fracture...

James Brady, the White House press secretary during President Ronald Reagan's first term in office, was 1 of 4 people (including the President) wounded during an attempted assassination attempt on President Reagan's life on March 30, 1981. John Hinckley, Jr. was found not guilty of this attempt by reason of insanity. The assassination attempt was a ploy by Hinckley, Jr. to impress the actress Jodie Foster. Brady was the most seriously injured of the 4 who were wounded. He suffered a gunshot wound to the left forehead that traveled through the left frontal lobe, corpus callosum, and then into the right frontal and temporal lobes...

INTRODUCTION: Ambulation during extravehicular activity on Mars may increase the risk of decompression sickness through enhanced bubble formation in the lower body. HYPOTHESES: walking effort (ambulation) before an exercise-enhanced denitrogenation (prebreathe) protocol at 14.7 psia does not increase the incidence of venous gas emboli (VGE) at 4.3 psia, but does increase incidence if performed after tissues become supersaturated with nitrogen at 4.3 psia. METHODS: VGE results from 45 control subjects who performed exercise prebreathe without ambulation before or during a 4-h exposure to 4...
