Kawasaki disease is an acute systemic inflammatory disorder, the etiology of which has not yet been established. The clinical manifestations are non-specific and are common to many pediatric infectious and immunologic diseases. In 2 cases presenting fever, cervical lymphadenopathy, and retropharyngeal abscess-like lesions on the neck shown in a computerized tomography (CT) scan, the diagnosis of Kawasaki disease was delayed. The patients were not responsive to antibiotic therapy, and fluid collection was not found during retropharyngeal aspiration. They showed typical Kawasaki manifestations over time and atrioventricular valve regurgitation in the echocardiogram. A diagnosis of Kawasaki disease should be considered in similar cases of fever and cervical lymphadenopathy. A CT scan that shows a retropharyngeal abscess-like lesion on the neck can be a false positive finding, and other laboratory exams, including echocardiography, should be performed as early as possible to avoid unnecessary medical and surgical procedures.

Liver abscess following ventriculoperitoneal (VP) shunting occurs very rarely. We report an unusual case of multiple liver abscesses caused by Staphylococcus capitis in a 50-year-old compromised woman due to a complicating VP shunt infection. We reviewed the nine cases of VP shunt complications reported in the English literature, and speculated that the most likely pathogenetic mechanism in our case is an infected peritoneal tip that migrated to and penetrated the liver, which subsequently caused the formation of multiple liver abscesses. The patient was successfully treated with percutaneous aspiration, drainage of the abscesses, intravenous antibiotics, and shunt revision. Awareness and vigilance of the possibility of liver abscess formation caused by VP shunt infection will help establish an early accurate diagnosis and therapeutic strategy.

Congenital dermal sinus (CDS) is a type of occult spinal dysraphism characterized by a midline skin dimple. A 12-month-old girl presented with fever and ascending quadriparesis. She had a midline skin dimple in the upper sacral area that had been discovered in her neonatal period. Imaging studies revealed a holocord intramedullary abscess and CDS. Overlooking CDS or misdiagnosing it as benign sacrococcygeal dimple may lead to catastrophic infection and cause serious neurological deficits. Therefore, further imaging work-up or consultation with a pediatric neurosurgeon is recommended following discovery of any atypical-looking dimples in the midline.

Retroperitoneal infections are rarer than intra-abdominal infections in children; however, they can lead to significant morbidity in cases of missed diagnosis. We present a case of retroperitoneal abscess caused by extended-spectrum β-lactamase-producing Escherichia coli in a 10-year-old female adolescent who failed to show clinical improvement following empirical antibiotic therapy.

We present a case of tuberculous spondylitis in which diagnosis was masked by a concomitant pyogenic infection. The patient had undergone percutaneous needle aspiration of an abscess in the cavity of the psoas muscle. Early results from the culture regimen showed isolation of methicillin-resistant Staphylococcus aureus. After eight weeks, mycobacterium tuberculosis was grown at regimen which was cultured at the same site. Initial isolation of pyogenic bacteria, considered to be highly virulent organisms, led to delayed diagnosis and treatment of the tuberculosis.

Spinal epidural abscess(SEA) is a rare condition in children. Classic symptoms are spinal ache, root pain, weakness and paralysis. The earliest symptoms of SEA in the pediatric age group are nonspecific and variable. Early diagnosis may be almost impossible when local spinal pain is inconspicuous or absent, when toxic epiphenomena divert attention from subtle signs of neurologic dysfunction and when the patient is an acutely distressed and uncooperative child. Failure to diagnosis and treat condition on a timely basis may lead to permanent neurolgic dysfunction or even death. This infection, usually located in the dorsal epidural space of the mid thoracic or lower lumbar regions, is the result of hematogenous dissemination of bacteria, usually Staphylococci, from foci of infection in the skin, or respiratory or urinary tracts. MRI was the diagnostic method of choice. A combination of antibiotics and surgical drainage remains the treatment of choice. Prognosis is excellent if surgery is performed before the development of neurologic deficit. We report a case of SEA in a child whose first presenting symptom was abdominal pain rather than spinal pain. A case is diagnosed by MRI and successfully treated with laminectomy and drainage and antibiotics.

The purpose of this study was to estimate the diagnostic availability of the common periapical lesions by using computer. The author used a domestic personal computer and rearranged the applied program appropriately with RF (Rapid File), a program to answer the purpose of this study, and then input the consequence made out through collection, analysis and classification of the clinical and radiological features about the common periapical lesions as a basic data. The 256 cases (Cyst 91, Periapical granuloma 74, Periapical abscess 91) were obtained from the chart recordings and radiographs of the patients diagnosed or treated under the common periapical lesions during the past 8 years (1983-1990) at the infirmary of Dental School, Chosun University. Next, the clinical and radiographic features of the 256 cases were applied to RF program for diagnosis, and the diagnosis by using computer was compared with the hidden final diagnosis by clinical and histopathological examination. The obtained results were as follows: 1. In cases of the cyst, diagnosis through the computer program was shown rather lower accuracy (80.22%) as compared with accuracy (90.1 %) by the radiologists. In cases of the granuloma, diagnosis through the computer program was shown rather higher accuracy (75.7%) as compared with the accuracy (70.3%) by the radiologists. 2. In cases of periapical abscess, the diagnostic accuracy was shown 88% in both diagnoses. 4. The average diagnostic accuracy of 256 cases through the computer program was shown rather lower accuracy (81.2%) as compared with the accuracy (82.8%) by the radiologists. 5. The applied basic data for radiographic diagnosis of common periapical lesions by using computer was estimated to be available.

Haemophilus aphrophilus is a fastidious gram-negative bacillus found in mouth of normal individuals. Though H. aphrophilus infection is quite rate, it includes such serious ones as endocarditis and brain abscess. The authors isolated H. aphrophilus from five patients with the diagnosis of lung abscess, conjunctivitis, brain abscess and facial masticator space abscess. Two of the patients died. Three of the patients also yielded other species of bacteria from the same specimens. One of the isolate was intermediately susceptible to amikacin and resistant to tobramycin, indicating the necessity of a routine susceptibility test in order to select the proper antimicrobial agents. Since H. aphrophilus can be differentiated from other similar organisms by morphological and biochemical characteristics, one should determie the possibility of this organism when fastidious gram-negative bacilli are isolated from blood or from sites adjacent to upper respiratory tract.

Tuberculosis is not a common cause of liver abscess and it is rarely considered in the differential diagnosis of a patient with hepatic mass. We report a case of tuberculous abscess of liver and spleen in a 15-year-old boy who presented with abdominal pain, fever and weight loss. The ultrasonographic and computed tomographic scan of the abdomen revealed multiple cystic lesions in the liver and spleen. Mycobacterium tuberculosis was cultured from the ascitic fluid and biopsy specimen of lymph node. Follow up CT scan of the abdomen after anti-tuberculosis medication for eighteen months showed complete resolution of the cystic lesions with calcified nodules.
