1/20. Sinusitis with contiguous abscess involvement of the clivus and petrous apices. Case report.A wide spectrum of diseases may involve the clivus, such as primary neoplasms, metastatic disease, and inflammatory, vascular, hematopoietic, and infectious processes. Of these, osteomyelitis of the skull base and/or clival-petrous abscess are unusual, but may occur as a result of contiguous spread from the paranasal sinuses, namely, the posterior ethmoid and sphenoid, as was demonstrated by this patient. In this case report we discuss the pertinent anatomy, imaging studies, pathogenesis, and medical and surgical management of this case.- - - - - - - - - - ranking = 1keywords = abscess (Clic here for more details about this article) |
2/20. Superolateral subperiosteal orbital abscess complicating sinusitis in a child.Orbital complications of sinusitis in children generally occur as a consequence of ethmoid sinusitis due to preferential spread across the lamina papyracea. A case is presented of a subperiosteal abscess (SPA) in the superolateral orbital wall complicating frontal sinusitis in a 6-year-old female. Congenital bony dehiscences exist in the lateral floor of the frontal sinus, which may allow direct spread of infection through to that region. While the general principles of managing orbital complications of sinusitis are applicable, the surgical approach for a SPA complicating frontal sinusitis differs from that of the typical medial SPA, and the clinician should be mindful of this variation when planning surgical treatment.- - - - - - - - - - ranking = 1keywords = abscess (Clic here for more details about this article) |
3/20. Orbital abscess due to acute ethmoiditis in a neonate.Orbital complications due to ethmoiditis are not uncommon in children. However, they are very rare in infants. A case of orbital abscess due to acute ethmoiditis in a 10 days old boy is reported. Causative microorganisms isolated from the operated specimen were Staphylococcus aureus and aspergillosis. Successful outcome was achieved following antimicrobial therapy, external ethmoidectomy, and surgical drainage of the abscess. The aetiopathogenesis and management of this clinical entity is discussed, with a brief review of the literature.- - - - - - - - - - ranking = 1.2keywords = abscess (Clic here for more details about this article) |
4/20. Neonatal orbital abscess.PURPOSE: To describe two cases of orbital abscess in neonates and to review the literature of orbital cellulitis in neonates. DESIGN: Two interventional case reports. methods: photographs, orbital computed tomography scans, and full pediatric examination were obtained in two cases of orbital abscess in neonates. RESULTS: Acute ethmoiditis with orbital abscess formation was found in both infants. In one of them, Staphylococcus aureus was identified as the source of infection. CONCLUSIONS: The clinical findings of our cases concur with the literature (eight cases) indicating that orbital abscess caused by Staphylococcal ethmoiditis is the most common form of orbital cellulitis in neonates.- - - - - - - - - - ranking = 1.6keywords = abscess (Clic here for more details about this article) |
5/20. Nasal septal abscess: an unusual complication of acute spheno-ethmoiditis.Nasal septal abscess complicating acute sinusitis is rare. There have been very few reports in the literature of this condition. We present a 12-year old-male with a nasal septal abscess complicating acute pansinusitis.- - - - - - - - - - ranking = 1.2keywords = abscess (Clic here for more details about this article) |
6/20. Bilateral cavernous sinus thromboses and intraorbital abscesses secondary to streptococcus milleri.PURPOSE: To report the first case of bilateral cavernous sinus thromboses and bilateral intraorbital abscesses secondary to streptococcus milleri. STUDY DESIGN: Single interventional case report. INTERVENTION AND TESTING: The findings of the ophthalmic evaluation, radiographic imaging, medical and surgical intervention, specimen cultures, and clinical course were analyzed. RESULTS: A 17-year-old female had bilateral proptosis, decreased vision in the left eye, and altered mental status at presentation. An orbital compartment syndrome developed in the left eye and purulent material was present after lateral canthotomy, suggestive of an intraorbital abscess. magnetic resonance imaging (MRI) scans revealed bilateral cavernous sinus thromboses, and subsequent computed tomographic (CT) scans revealed bilateral intraorbital abscesses in the setting of acute ethmoid and sphenoid sinusitis. Antibiotic treatment and surgical drainage of the orbital abscess and sinuses was performed, and specimen cultures revealed S. milleri. After surgery, the patient experienced hearing loss and a right internal capsule infarct, in addition to complete vision loss in the left eye. A second intraorbital abscess developed in the right eye and was drained surgically. The vision remained 20/20. CONCLUSIONS: streptococcus milleri is a virulent organism with a propensity to form abscesses in multiple areas of the body and should be considered as a possible etiologic agent in abscess formation of the orbit and cavernous sinus thrombosis.- - - - - - - - - - ranking = 2.2keywords = abscess (Clic here for more details about this article) |
7/20. arcanobacterium haemolyticum sinusitis and orbital cellulitis.We present a case of sinusitis and orbital cellulitis in a 9-year-old girl caused by the Gram-positive bacillus arcanobacterium haemolyticum. In addition to antimicrobial chemotherapy, two surgical procedures were required to drain the ethmoid and maxillary sinus cavities and a subperiosteal abscess.- - - - - - - - - - ranking = 0.2keywords = abscess (Clic here for more details about this article) |
8/20. diffusion-weighted imaging of cerebritis.Restricted water diffusion has been used to distinguish pyogenic abscess from other rim-enhancing brain masses; however diffusion-weighted imaging of cerebral infection before capsule formation has rarely been described. We report a case of fungal cerebritis in which water diffusion was more restricted than that of normal contralateral brain and the measured diffusion coefficient was in the range of that reported for pyogenic brain abscess. In the proper clinical setting, cerebritis should be considered in the differential diagnosis of an ill-defined focal brain mass associated with markedly restricted water diffusion.- - - - - - - - - - ranking = 0.4keywords = abscess (Clic here for more details about this article) |
9/20. Recurrent periorbital cellulitis in a child. A random event or an underlying anatomical abnormality?We present a case of recurrent periorbital cellulitis in a child. From the age of 2 years the child was admitted with periorbital cellulitis a total of six times with the first five episodes responding to conservative management with intravenous antibiotics. On the sixth admission endoscopic surgical treatment was carried out. Two abnormalities were noted: an anatomically abnormal uncinate process and an isolated abscess in an ethmoidal cell. It is believed that the abnormal uncinate process caused obstruction of the osteomeatal area, predisposing to recurrent peri-orbital cellulitis. We discuss the importance of early imaging and surgery in recurrent periorbital cellulitis.- - - - - - - - - - ranking = 0.2keywords = abscess (Clic here for more details about this article) |
10/20. Neonatal disseminated methicillin-resistant staphylococcus aureus presenting as orbital cellulitis.orbital cellulitis and abscess are known complications of ethmoiditis in children, but they are very rare in the newborn. The authors report a case of orbital abscess caused by methicillin-resistant staphylococcus aureus (MRSA) in a four-week-old neonate born four weeks prematurely.- - - - - - - - - - ranking = 0.4keywords = abscess (Clic here for more details about this article) |
