PURPOSE: To describe radiologic findings of burn-associated persistent candidemia of the thorax. MATERIALS AND METHODS: This study included 42 patients with major burns in whom blood culture had shown the presence for more than 24 hours of persistent candidemia. The duration of positive culture for candidiasis ranged from two to 67 days(mean, 15 days). Radiographic(n=42) and thin-section CT findings(n=13) were retrospectively analyzed. The onset, pattern, size, distribution and persistence of parenchymal abnormalities as well as the presence or absence of pleural effusions, mediastinal lymphadenopathy and cardiomegaly were assessed. RESULTS: On chest radiographs, positive findings were noticed in 61.9%(26/42) and on thin-section CT, in 76.9%(10/13). The most frequent radiographic finding was pulmonary nodule(s), observed in 14 patients(33.3%). in 13, these were bilateral. Bronchovascular bundle thickening(n=6, 14.3%), consolidation(n=4, 9.5%), cardiomegaly(n=6, 14.3%) and pleural effusion(n=4, 9.5%) were also observed. Those lesions appeared eight to 129 days(mean, 33days) after the burn. Radiographic abnormalities persisted for seven to 115 (mean, 35) days, regardless of the treatment. Thin-section CT showed parenchymal abnormalities in 10/13 patients(76.9%) and subpleural nodules of less than 1cm in diameter and without halo in all patients. Cardiomegaly, pleural effusion and mediastinal adenopathy were observed on CT in 5(38.5%), 4(30.8%) and 2(15.4%) of the 13 patients, respectively. CONCLUSION: In a high proportion of patients with burn-associated candidemia, chest radiograph and thin-section CT findings were positive. The most frequent radiographic parenchymal abnormality was multiple bilateral nodules.

Acute focal bacterial nephritis(AFBN) is an unusual form of localized renal infection, which has various imaging findings and should be distinguished from abscess or other renal masses. Clinical symptoms are similar to other urinary tract infections but the diagnosis needs a CT or sonographic confirmation. Treatment, which is nonoperative, consists of intensive antibiotic therapy. We report three cases of AFBN with urinary tract infection in an 11-month-old, 9-month-old female and 8-month-old male patients, respectively. The confirmative diagnosis was done by localized intrarenal solid mass lesion by sonography. They were treated with intravenous and oral antibiotics for 6, 4 and 2weeks, respectively. Follow-up urinalysis, urine culture and sonographic finding were normal after treatment.

Septic pulmonary emboli(SPE) is derived from a variety of sources, including infected heart valves, peripheral sites of septic thrombophlebitis and infected venous catheters or pacemaker wires. In adult intravenous drug users, the most common cause of septic emboli is tricuspid valve endocarditis, but infective endocarditis in the non-complicated ventricular septal defect is a relatively rare condition in infants and children. Early detection, along with prompt administration of broad-spectrum antibiotics, is an important factor in the prognosis of patients with SPE. Unfortunately, initial clinical diagnosis is often difficult; a heart murmur may or may not be present and blood cultures may remain negative early in the course of infection. And so characteristic chest CT and chest radiographic findings are helpful in non-invasive diagnostic method for early detection. We experienced a case of pulmonary septic emboli associated with ventricular septal defect in a 6-year-old girl. The diagnosis was made on the basis of clinical features, echocardiography, chest x-ray and chest CT. We report this case with brief review related literatures.

We report a very rare case of congenital adrenal agenesis presented with adrenal insufficiency in a 4-day-old female newborn. She was admitted with darkish skin color and seizure. Her external genitalia was normal. Elevated serum level of adrenocorticotropic hormone and increased plasma renin activity were observed. Plasma cortisol level and aldosterone level were decreased. Pelvic ultrasonography revealed bilateral agenesis of adrenal glands. Six exons of the steroidogenic factor-1 (SF-1, NR5A1) gene and their intronic flanking sequences were normal. Now, she is continuously receiving replacement doses of glucocorticoids and mineralocorticoids under adrenal insufficiency. Her growth and development are completely normal. We propose that when a patient presents with 46, XY disorder of sex development or normal female genitalia with adrenal insufficiency, SF-1 gene mutation study should be included in the differential diagnosis.

Shaken baby syndrome (SBS) is a form of child abuse that can cause significant head injuries, of which subdural hematoma (SDH) is the most common manifestation. We report the MRI findings of chronic SDH in three cases of SBS, involving two-, three- and eight-month-old babies. The SDH signal was mostly low on T1-weighted images and high on T2-weighted images, suggesting chronic SDH. In chronic SDH, a focal high signal on T1-weighted images was also noted, suggesting rebleeding. Contrast-enhanced MRI revealed diffuse dural enhancement.

PURPOSE: To clarify the distribution of joint effusion, and the relationship between type of injury andamount of joint effusion seen in traumatic knee joint magnetic resonance imaging (MRI). MATERIALS AND METHODS: Weretrospectively reviewed the MR images of 400 patients with traumatic knee joint effusion. The knee joint spacewas divided into four compartments: central portion (para-ACL, para-PCL), suprapatellar pouch, posterior femoralrecess, and subpopliteal recess, and we then compared the amount and distribution of effusion. For statisticalanalysis, the chi-square test was used. RESULTS: Among 400 MRI examinations of joint effusion, 383 knees (96%)showed homogeneous low intensity on T1-weighted images, and - except for ten cases of fluid-fluid levels-homogeneous high intensity on T2-weighted images. Knee joint effusion was clearly shown to be distributed mainlyin the suprapatellar pouch (345, 86%), followed by the central posterior femoral recess, and the subpoplitealrecess (p<0.001). Extensive joint effusion was less frequently found in the normal group, but was occasionallyfound in the combined injury group (p<0.001). The relationship between amount of joint effusion and type ofinjury was statistically significant (p<0.001), except in the case of medial and lateral collateral ligamentinjury. CONCLUSIONS: The distribution of joint effusion in patients with traumatic knee disorders is a reflectionof anatomic communication, and whether the amount of joint effusion was small or large depended on the anatomicallocation and type of injury.
