1/27. CT and MRI findings in primitive pituitary abscess: a case report and review of literature.Pituitary abscess is not rare. Clinical and radiological features in a primitive pituitary abscess are reported. Transphenoidal surgery revealed an abscess. Preoperative diagnosis of pituitary abscess remains difficult. Sellar round cystic mass isointense to grey matter on T1, high intensity signal on T2, with a peripheral rim enhancement following gadolinium injection associated with thickened stalk and diabetes insipidus may be suggestive of pituitary abscess.- - - - - - - - - - ranking = 1keywords = abscess (Clic here for more details about this article) |
2/27. A case of costochondral abscess due to corynebacterium minutissimum in an hiv-infected patient.corynebacterium minutissimum, known as the causative agent of erythrasma, has recently been reported as a clinically significant pathogen in the immunocompromised host. We report for the first time the possible involvement of a multidrug-resistant C. minutissimum strain in a costochondral abscess occurring in an hiv-infected patient.- - - - - - - - - - ranking = 0.55555555555556keywords = abscess (Clic here for more details about this article) |
3/27. Native valve endocarditis with aorta-to-left atrial fistula due to corynebacterium amycolatum.Infective endocarditis remains a pathology with a high rate of complications and mortality. One of the most dramatic complications is abscess formation. A rare evolution of abscess formation is the development of fistula. We describe an 88-year-old woman with an aortic root abscess and aorta-to-left atrial fistula. To our knowledge this has only been described with streptococcus species as causative micro-organism. In this case the abscess was caused by corynebacterium amycolatum, which is an infrequently found micro-organism.- - - - - - - - - - ranking = 0.44444444444444keywords = abscess (Clic here for more details about this article) |
4/27. Infected bullae: a recognizable entity.Infected bullae are seldom diagnosed. They are frequently confused with pulmonary abscess. We present a case with a characteristic evolution. Bullae were identified previous to the infection. The illness developed gradually with scanty sputum, pleuritic pain and finally a febrile illness. fever abated 48 hours after initiating two weeks of therapy with intravenous clindamycin and amikacin. As it is commonly seen, radiographic resolution was slow but it was complete in 8 weeks. Recognition of infected bullae is important to avoid inappropriate diagnostic or therapeutic interventions.- - - - - - - - - - ranking = 0.11111111111111keywords = abscess (Clic here for more details about this article) |

Isolations of corynebacterium kroppenstedtii from a breast abscess.The recently described species corynebacterium kroppenstedtii was isolated from a breast abscess in a 38-year-old woman on two occasions.

7/27. A case series on chronic canaliculitis.INTRODUCTION: Primary chronic canaliculitis is an uncommon disease, which is often misdiagnosed and insufficiently treated. We present two cases of canaliculitis caused by two different organisms, Actinomycetes spp. and arcanobacterium haemolyticum. To the best of our knowledge, canaliculitis due to arcanobacterium haemolyticum has not been reported before. patients AND methods: The two cases described in this series show typical clinical features of canaliculitis with an inflamed upper canaliculus, not responsive to topical antibiotics. Appropriate treatment was delayed as they were initially treated for conjunctivitis. Both patients were treated with a canaliculotomy, with curettage and subsequent treatment with topical and systemic penicillin. The contents were sent for microbiological examination. RESULTS: There was complete resolution following treatment. actinomyces spp. was grown from one patient as expected. However, in the second patient, arcanobacterium haemolyticum was isolated. Although this organism was not expected, the patient did respond to similar, conventional treatment. DISCUSSION: actinomyces spp. is a cast-forming Gram-positive anaerobe. They are difficult to isolate and identify and can cause infections of hollow spaces with formation of canaliculiths. arcanobacterium (corynebacterium) haemolyticum closely resembles actinomyces (corynebacterium) pyogenes. Ocular infections reported with this organism include orbital cellulitis and subperiosteal abscesses. The difficulty encountered in the isolation and identification of these organisms is discussed and the need for thorough curettage in the treatment of persistent or recurrent canaliculitis is emphasised. CONCLUSION: Chronic canaliculitis should be considered in any patient who presents with chronic or recurrent conjunctivitis. Definitive cure will not be affected until all concretions are removed, either at surgery or by mechanical expression.- - - - - - - - - - ranking = 0.11111111111111keywords = abscess (Clic here for more details about this article) |
8/27. corynebacterium striatum: an underappreciated community and nosocomial pathogen.corynebacterium striatum (CS) is an underappreciated human pathogen that has been associated with serious infections in both immunocompetent and immunocompromised hosts. CS infections tend to be more frequent in males and major infection sites have included blood stream, lung, and central nervous system. Most are nosocomially acquired and there is a significant association with medical devices ranging from intravascular catheters to central nervous system drainage devices. Empiric therapy with vancomycin is advisable as susceptibility to other agents is variable. Treatment may also include removal of foreign material such as an intravascular catheter. The present review describes the wide spectrum of infections associated with CS and we add a unique case of CS pancreatic abscess where treatment included linezolid.- - - - - - - - - - ranking = 0.11111111111111keywords = abscess (Clic here for more details about this article) |
9/27. Pancreatic abscess caused by corynebacterium coyleae mimicking malignant neoplasm.A 50-year-old female was referred to our hospital because of postprandial epigastric pain and pancreatic head mass. On admission, an elastic hard mass with tenderness was palpable in the epigastric region. Laboratory findings showed no abnormalities, except for a slightly elevated c-reactive protein value and iron deficiency anemia. serum levels of pancreatic enzymes and tumor markers were also within the reference range. Computed tomography (CT) demonstrated a 5-cm heterogenous mass at the head of the pancreas. angiography showed that gastroduodenal artery was transformed and narrowed by the mass. Smooth stenosis of portal vein was also observed. Fusion CT-positron emission tomography with 2-deoxy-2-[F]fluoro-D-glucose demonstrated a focus of increased uptake in the pancreatic head mass. We suspected the mass of malignancy but, surprisingly, tumor size was gradually decreased without any therapies. biopsy specimens from the mass of the pancreas showed marked inflammatory cell infiltration and marked interstitial fibrosis without malignant cells. Thereafter, we could isolate corynebacterium coyleae from the biopsy specimen. We diagnosed the mass as a pancreatic abscess caused by C. coyleae and started with the intravenous antibiotics therapy. Subsequent follow-up CT and ultrasonography showed dramatic improvement in pancreatic mass.We present here a case of pancreatic abscess which was difficult to differentiate from malignant lesion by various imaging studies. Moreover, we could culture and identify C. coyleae which had never been reported to be the source of pancreatic abscess.- - - - - - - - - - ranking = 0.77777777777778keywords = abscess (Clic here for more details about this article) |
10/27. Native valve endocarditis due to corynebacterium group JK.We report a case of a 32-yr-old woman on chronic intermittent haemodialysis, who developed endocarditis due to a corynebacterium group JK, involving both the native aortic and mitral valves. Despite a four-week treatment with vancomycin, an aortic root abscess developed. The diagnosis was confirmed on autopsy.- - - - - - - - - - ranking = 0.11111111111111keywords = abscess (Clic here for more details about this article) |
