Streptococcus constellatus is a member of Streptococcus milleri group which is a subgroup of Viridans streptococci, first described by Guthof in 1956 after being isolated from dental abscesses. S. constellatus, a gram positive, non-sporing, non-motile, catalase negative cocci, is the normal flora of the oropharyngeal, gastrointestinal and urogenital tract. It is not a commonly encountered pathogen but has a propensity to form abscesses and cause bacteremia in the immunocompromised patient. Here, we report a 78-year-old man with sepsis due to Streptococcus constellatus liver abscess. The patient had a history of hypertension, stroke, benign prostatic hyperplasia, vascular dementia and myocardial infarction status post coronary artery bypass grafting. There has been no particular link between any of these conditions to S. constellatus. However, immunocompromised status predisposes to fulminant infection and formation of abscesses. The patient was febrile with a temperature of 99.1°F, blood pressure of 143/73 mmHg and the heart rate (HR) of 98. Labs revealed a leukocytosis of 16.90 K/uL, hemoglobin 11.8 g/dL, hematocrit 35.8%, total bilirubin 1.7 mg/dL, direct bilirubin 1.0 mg/dL, aspartate aminotransferase (AST) 44 IU/L, alanine aminotransferase (ALT) 28 IU/L, alkaline phosphatase (ALKP) 176 IU/L and lactate dehydrogenase (LDH) was 290 IU/L. He was started on intravenous Maxipime and Unasyn which was switched to Rocephin and Clindamycin based on the Infectious disease recommendations. Metronidazole was also started and the serologies were sent for Entamoeba histolytica. Computerized tomography (CT) scan showed an abscess in the right lobe of the liver which was finally drained using an interventional radiology (IR)-guided approach. The cultures from the fluid and blood yielded S. constellatus and thus Metronidazole was discontinued. The patient improved after a few days and the drainage catheter was pulled out and the patient discharged in stable condition.

INTRODUCTION
Pancreatic pseudocysts are abnormal mature collections of pancreatic fluid that can develop in association with acute or chronic pancreatitis. Here, we share the discovery of an infected hepatic subcapsular pseudocyst of the pancreas causing septic shock following endoscopic retrograde cholangiopancreatography (ERCP).
PRESENTATION OF CASE
A 55-year-old woman with ethanol-related chronic pancreatitis and biliary stricture was transferred to the ICU for hypotension 8 hours following ERCP. Examination revealed mild right upper quadrant tenderness without sign of peritonitis. Laboratory studies were notable for leukocytosis (14.6 k/L) and slightly elevated serum lipase (489 U/L). Abdominal CT scan revealed a previously undescribed subcapsular fluid collection. She underwent CT-guided percutaneous subcapsular drainage with return of opaque yellowish fluid. Fluid analysis showed elevated lipase of 62,901 U/L with cultures positive for ESBL , , and .
DISCUSSION
A majority of pancreatic pseudocysts develop in peripancreatic regions, while, in a recent study, over a quarter of cases were found in usual sites. The management of subcapsular pseudocysts has not been standardized and often involves endoscopic or percutaneous drainage. Operative intervention is reserved for severe infection or rupture in patients with intrahepatic pseudocysts. Rarely do subcapsular pseudocysts become infected. In this case, we postulate the pseudocyst became seeded by bacteria during ERCP resulting in infection and then sepsis.
CONCLUSION
This case report highlights an atypical presentation of pancreatic pseudocyst as well as a rare septic complication of ERCP.

Congenital hepatic cysts are a common disorder. Usually they are asymptomatic and do not have to be treated. However, some serious complications can occur. We report here the case of an 86-year old patient who has been treated by a percutaneous drainage for an infected solitary hepatic cyst due to urinary sepsis. She was admitted to the Department of Internal Medicine for epigastric pain with fever and chills. The patient was treated for a urinary tract infection 3 weeks ago by her General Practitioner. On admission, blood tests showed 21 620 neutrophils per microliter with a C-reactive protein level at 443.7 mg/L, procalcitonin > 200 ng/mL, total bilirubin at 1.43 mg/dL, lactate dehydrogenase at 666 U/L and alanine aminotransferase at 227 U/L. Urinalysis and hemocultures highlighted the presence of Escherichia coli and Streptococcus constellatus. The abdominal tomodensitometry indicated the presence of a left hepatic biliary cyst with banal appearance. She was first treated with intravenous amoxicillin clavulanic acid. After a few days, another abdominal tomodensitometry with contrast pinpointed a large abscess of 11 centimeters in diameter extending to liver segments II and IV with a similar small lesion in segments IV and V. clindamycin per os was added to the treatment because of its good diffusion in tissues. Percutaneous drain was inserted under tomodensitometric control and stayed in place until the follow-up at three weeks. Bacteriologic culture on the fluid sample demonstrated the presence of Escherichia coli and Streptococcus constellatus. The abscess completely regressed after 6 weeks of treatment and the biologic abnormalities resolved at the same time.

Review
We report a rare case of suppurative thrombophlebitis of the posterior neck caused by Streptococcus constellatus. A 69-year-old female patient was admitted to the hospital with neck pain and fever, which had persisted for 16 days prior to hospitalization. On day 1 (day of admission), blood cultures (later identifying S. constellatus) were performed, and ceftriaxone (CTRX) IV (2 g SID) was started. On day 3, suppurative thrombophlebitis of the posterior neck was diagnosed by CT scan. The antimicrobials were changed from CTRX to ampicillin/sulbactam IV (12 g QID) to guard against the possibility of complicated infection with Fusobacterium spp. or Prevotella spp. On day 17, a CT scan revealed that the thrombus remained. Therefore, oral edoxaban (30 mg SID) was started. On day 27, the patient was discharged after her medication was changed to oral amoxicillin/clavulanate (1500 mg/375 mg TID). On day 33, the amoxicillin/clavulanate was changed to oral cefaclor (1500 mg TID) and edoxaban was discontinued due to itching. On day 45, the course of cefaclor was completed. The patient went on to follow an uneventful course with no relapses or complications for two years since the conclusion of treatment. These results suggest that when a patient presents with persistent neck pain accompanied by fever, suppurative thrombophlebitis of the posterior neck should be considered. In antimicrobial therapy, the treatment could be switched from intravenous to oral. In addition, direct-acting oral anticoagulants may be an alternative to other forms of anticoagulants.

Infective endocarditis (IE) is a severe infection of the endocardium and cardiac valves by multiple etiologic agents. Clinical presentation can be acute or subacute based on the host immunity and the causative agent's virulence. Although are responsible for most community-acquired native valve bacterial IE, is an infrequent cause. can rarely infect prosthetic cardiac valves. A middle-aged white male with poorly controlled type 2 diabetes mellitus was transferred to our facility for suspected stroke with an initial presentation of acute encephalopathy of uncertain duration. Transthoracic echocardiogram revealed a left ventricular apical mural vegetation, and brain imaging displayed multiple white matter hypodensities indicative of numerous small strokes. Blood cultures were positive for . Clinical presentation was unusual with an acute encephalopathy due to multiple septic emboli and primary mural IE with high-grade bacteremia due to . PubMed medical literature review reveals this to be a rare clinical presentation by an uncommon etiological agent with an infrequent echocardiogram finding.

are gram-positive cocci belonging to the group that have a propensity to cause bacteremia and abscesses, especially in immunocompromised patients. Here, we report the case of a 39-year-old male who was initially admitted to the hospital for diabetic ketoacidosis. During the hospitalization, he developed sepsis and blood cultures grew . CT imaging revealed multiple hepatic abscesses. A periapical abscess of the left mandibular central incisor found on CT Scan of face was identified as the likely source of infection. IR-guided drainage was performed however the patient went on to develop septic shock despite attempted source control and IV antibiotic therapy. Repeat imaging showed persistent hepatic abscesses in addition to new intraperitoneal abscesses necessitating exploratory laparotomy, drainage and abdominal washout. Fluid cultures grew and common enteric flora. Our report highlights the need for high clinical suspicion in cases of bacteremia to obtain diagnostic imaging for any abscess formation. Prolonged antibiotic therapy is a must and imaging guided or surgical drainage may be needed.

is an oropharyngeal commensal Gram-positive coccus, frequently associated with the respiratory tract. is part of the or group, which has traditionally been considered to have propensity to cause empyema and purulent abscesses, a property that is sometimes overlooked as the severity of infections it causes may have a varying degree. In this case, we present the case of a 54-year-old male with known liver cirrhosis who developed a severe empyema during an acute liver failure episode, requiring extensive decortication and prolonged hospital admission.

(SC) is a species of belonging to the group, along with and . Despite its commensal nature, underlying risk factors and medical conditions might lead to various anatomic site infections caused by this opportunistic pathogen. Although SC infections have mostly been associated with bacteremia, some case reports of abscess and empyema formation have been documented. Herein, we report a case of a middle-aged female patient who initially presented with radiculopathy symptoms. Subsequent neurologic imaging revealed a pyogenic abscess along paravertebral muscles, which was found to be caused by SC. The patient was successfully treated with abscess drainage from the lumbar zone and antibiotics, and the symptoms of radiculopathy have completely resolved.

is usually a benign, commensal bacteria but has increased incidence in blood cultures and abscesses. This pathogenic involvement is most prevalent in individuals with underlying medical conditions, such as solid tumors and type 2 diabetes mellitus, as well as in cases of community-acquired infections. We report a 43-year-old male with a right medial thigh ulcer and necrotic scrotal skin. The wound culture from surgical debridement grew and histology was consistent with stage III necrotizing fasciitis. Regardless of etiology, the mortality rate of patients with necrotizing fasciitis is greatly decreased with early intervention and thorough surgical debridement.

RATIONALE
Empyema caused by Streptococcus constellatus is rare in patients without underlying diseases. However, the importance of the Streptococcus anginosus group, which consists of S constellatus, S anginosus, and Streptococcus intermedius, as causative organisms of empyema has been increasing.
PATIENT CONCERNS
A 78-year-old man initially presented with dyspnea and chills for 4 days. He had no medical history.
DIAGNOSIS
Chest X-ray and chest computed tomography showed a large and multiloculated pleural effusion with an air bubble on the right side. Cultivation of the pleural effusion using clone library analysis of the 16S rRNA gene revealed S constellatus positivity.
INTERVENTIONS
The patient was treated by drainage of the pleural effusion and intravenous ceftriaxone and clindamycin for the possibility of anaerobes, followed by 10 weeks of oral antibiotics.
OUTCOMES
On the 11th day of admission, the thoracic drainage tube was removed. After 1 year of treatment, there were no sequelae of empyema.
LESSONS
Although S constellatus can cause serious infections in patients with underlying diseases and immunosuppression, physicians need to consider S constellatus infection in community-acquired empyema in elderly individuals. It should be treated with early pleural drainage and antibiotics to avoid surgical decortication and prolonged hospitalization.
