BACKGROUND: Novel therapeutic agents recently introduced for the treatment of cancer have several unusual side effects. An increased incidence of renal cystic lesions, often with features concerning for malignancy or infection, has been reported in patients with anaplastic lymphoma kinase (ALK) - rearranged advanced non-small cell lung cancer (NSCLC) treated with Crizotinib. Many of these lesions undergo spontaneous resolution despite developing complex features on imaging. We assess the incidence and patterns of evolution of Crizotinib Associated Renal Cysts [CARCs] at our institute and provide histopathology correlation of their benign nature...

BACKGROUND: Colobronchial fistula (CBF) is rare and easy to be delayed in clinic. There is no systemic study about this disease. The pathogenesis, clinical presentations, diagnosis and treatment of CBF were analyzed in this study. METHODS: The clinical data from 37 cases of CBF, which included one case in our institute and the other 36 cases in literature from January 1960 to August 2016, were reviewed and analyzed. The etiology, clinical presentations, diagnostic and therapeutic methods, and outcomes were summarized...

Surgicel(®) (Ethicon, North Ryde, NSW, Australia) is an absorbable sheet of oxidized cellulose polyanhydroglucuronic acid polymer used as an hemostatic in cardiovascular and thoracic surgery. In some cases, the retained material may cause foreign body granulomatous reactions and simulate tumor recurrence, an abscess, an hematoma, or an infection. We report the case of a 55-year-old patient who was operated of a lung adenocarcinoma. In the thoracic computed tomography scan 1 year after the surgery, a right paratracheal lymph node was detected, so endobronchial ultrasound-guided transbronchial needle aspiration (EBUS-TBNA) was performed suspecting recurrence of the tumor...

Abscess formation in lung cancer after transbronchial biopsy (TBB) is a rare complication with no standard consensus on a coping strategy or prophylaxis. We describe an instructive case of lung cancer which developed into an abscess after TBB. An 80-year-old man with poorly controlled diabetes mellitus underwent TBB for diagnosing a mass lesion in the left upper lobe. The TBB specimen confirmed a diagnosis of lung cancer, and he was scheduled for radical surgery. However, the tumour was revealed to have progressed into an enlarged abscess 24 days after TBB...

BACKGROUND: Spilled gallstones are common during laparoscopic cholecystectomy; however, they rarely lead to postoperative complications. Perihepatic abscesses develop in < 0.1% of patients with spilled gallstones and are typically contained within the peritoneal cavity. CASE REPORT: We present a 57-year-old man with history of cholecystectomy 2 years prior who presented with cough and flank pain and was discovered to have a perihepatic abscess invading his lung and kidney secondary to a spilled gallstone...

REVIEW
Kenneth V I Rolston
Solid tumors are much more common than hematologic malignancies. Although severe and prolonged neutropenia is uncommon, several factors increase the risk of infection in patients with solid tumors, and the presence of multiple risk factors in the same patient is not uncommon. These include obstruction (most often caused by progression of the tumor), disruption of natural anatomic barriers such as the skin and mucosal surfaces, and treatment-related factors such as chemotherapy, radiation, diagnostic and/or therapeutic surgical procedures, and the increasing use of medical devices such as various catheters, stents, and prostheses...

Prostatic abscess is a rare entity with an incidence of 0.5%-2.5% in all prostate diseases and usually occurs in the 5th and 6th decades of life with immunocompromised status. Prostatic abscess might be a process of evolution from acute prostatitis. Klebsiella pneumoniae is the leading microorganism in the diabetic patients of prostatic abscess in Taiwan. A 60-year-old diabetic man, with a one-week history of acute bacterial prostatitis was reported in this study, presenting to the emergency department with sudden altered mental status...

A 35-year-old man was admitted to an intensive care unit with unilateral facial swelling and septic shock after multiple presentations to the emergency department with non-specific unilateral pain over the parotid area. A CT scan of his neck showed diffuse right-sided facial soft tissue infection, mastoid effusion and temporal lobe cerebritis. The upper lobes of his lungs had cannonball lesions that were suggestive of septic lung metastases. Blood cultures and ear canal swabs were positive for Burkholderia pseudomallei The temporal lobe cerebritis eventually developed into an abscess, necessitating a cortical mastoidectomy, craniectomy and temporal lobectomy...

The interposition of a portion of the colon between the liver and the diaphragm is called Chilaiditi sign and discovered incidentally during radiological study for other reasons and usually asymptomatic presentation. When the discovery is accompanied by clinical symptoms such as abdominal pain, nausea, vomiting, bloating, constipation called Chilaiditi Syndrome. The Chilaiditi sign is a very rare condition, and the Chilaiditi syndrome is even more, especially if associated with other acute diseases. We report the case of a man of 41 years was admitted with right upper quadrant abdominal pain, nausea, vomiting, difficulty was diagnosed with radiographic and tomographic images making the differential diagnosis with lung abscess and diaphragmatic hernia...

BACKGROUND: Postmortem imaging (PMI) refers to the imaging of cadavers by computed tomography (CT) and/or magnetic resonance imaging (MRI). Three cases of cerebral infarctions that were not found during life but were newly recognized on PMI and were associated with severe systemic infections are presented. CASE PRESENTATIONS: An 81-year-old woman with a pacemaker and slightly impaired liver function presented with fever. Imaging suggested interstitial pneumonia and an iliopsoas abscess, and blood tests showed liver dysfunction and disseminated intravascular coagulation (DIC)...

Matthew T Koroscil, Timothy R Hauser
Pulmonary infarction is an infrequent complication of pulmonary embolism due to the dual blood supply of the lung. Autopsy studies have reported cavitation to occur in only 4-5% of all pulmonary infarctions with an even smaller proportion of these cases becoming secondarily infected. Patients with infected cavitating pulmonary infarction classically present with fever, positive sputum culture, and leukocytosis days to weeks following acute pulmonary embolism. We describe a rare case of acute pulmonary embolism with pulmonary infarction leading to cavitation and subsequent abscess formation requiring left lower lobe resection...

Brain abscess commonly occurs secondary to an adjacent infection (mostly in the middle ear or paranasal sinuses) or due to hematogenous spread from a distant infection or trauma. Pulmonary arteriovenous fistulas (AVFs) are abnormal direct communications between the pulmonary artery and vein. We present two cases of brain abscess associated with asymptomatic pulmonary AVF. A 65-year-old woman was admitted with a headache and cognitive impairment that aggravated 10 days prior. An magnetic resonance (MR) imaging revealed a brain abscess with severe edema in the right frontal lobe...

CLINICAL ISSUE: Despite a considerable number of antimicrobial agents and interdisciplinary treatment options, lower respiratory tract infections are still associated with high morbidity and mortality rates. Infections of the respiratory tract can lead to severe complications, such as empyema, lung abscesses and acute respiratory distress syndrome (ARDS). Besides intrapulmonary complications pneumonia can also impair other organs due to a systemic inflammatory response. Underlying cardiovascular diseases, such as chronic heart failure, arteriosclerosis and dysrhythmia can either deteriorate due to infections or be newly manifested as a result of pneumonia...

We herein report the case of 75-year-old Japanese female with a community-acquired lung abscess attributable to Streptococcus pneumoniae (S. penumoniae) which extended into the chest wall. The patient was admitted to our hospital with a painful mass on the left anterior chest wall. A contrast-enhanced chest computed tomography scan showed a lung abscess in the left upper lobe which extended into the chest wall. Surgical debridement of the chest wall abscess and percutaneous transthoracic tube drainage of the lung abscess were performed...

Fusobacterium nucleatum was found in patients with empyema or pulmonary abscess, using paromomycin-vancomycin Brucella HK agar. In vitro examination revealed that growth of the strains differed significantly in different media. Clinicians should be aware that suboptimal F. nucleatum cultivation methods may result in an underestimation of its frequency.

Amoebiasis is a human disease produced by Entamoeba histolytica which causes widespread mortality and morbidity worldwide through diarrheal disease and abscess establishment in parenchymal tissues such as liver, lung, and brain. The true prevalence of infection is unknown for most areas of the world due to the difficulty to characterise Entamoeba histolytica versus other non-pathogenic amoebas with identical morphology, as Entamoeba dispar, and Entamoeba moshkovskii. To overcome microscopy misidentification issues, we tested a nested multiplex polymerase chain reaction (PCR) and a real-time PCR on 194 stool samples collected from incoming dysentery patients in Cairo hospitals diagnosed with E...

An acute dry cough results commonly from bronchitis or pneumonia. When a patient presents with signs of infection, respiratory crackles, and a positive chest radiograph, the diagnosis of pneumonia is more common. Antibiotic failure in a patient being treated for community-acquired pneumonia requires further investigation through chest computed tomography. If a lung mass is found on chest computed tomography, lung empyema, abscess, and cancer need to be included on the differential and managed aggressively. This report describes a 55-year-old Caucasian male, with a history of obesity, recovered alcoholism, hypercholesterolemia, and hypertension, presenting with an acute dry cough in the primary care setting...
