Urinary tract infection (UTI) is most commonly diagnosed bacterial infection in febrile infants. Renal abscess is a very rare complication of UTI in children. Early diagnosis and treatment with appropriate antibiotics are important because renal scar correlates positively with the time of treatment. Renal ultrasonography and abdominal computerized tomography facilitates an earlier diagnosis and is also useful in establishing percutaneous drainage. Extended broad spectrum antibiotics therapy alone can be effective in most types of renal abscesses in infant, but some antibiotics-resistant cases need surgical drainage or nephrectomy. We report a case of a infant UTI, that progressed to renal abscess despite early antibiotic treatment and was treated with US guided percutaneous needle aspiration.

A 65-year-old male was admitted to our hospital complaining of painful swelling of right sternocostoclavicular area. In the past history, he had no specific disease including trauma. After admission, chest CT and neck CT showed right empyema and right cervical abscess. Empyemectomy was performed through open thoracotomy and fistulous tract was detected on right parietal pleura and right sternocostoclavicular area. Osto-myelitis was also detected on right sternocostoclavicular area and removal of right cervical abscess, partial resection of proximal clavicle, resection of chondral portion of 1st rib, and partial resection of manubrium were performed. Empyema that extends from sternocostoclavicular osteomyelits, as in this case, is rare. Herein we report a case of loculated empyema with sternocostoclavicular osteomyelitis and neck abscess.

A healthy, 14-year-old boy presented with right hip pain and consequent fever after falling out of bed while sleeping. The patient could not walk and complained of severe pain with active and passive motion, which consisted mainly in extension and internal rotation of the right hip. Laboratory analysis of the peripheral blood identified leukocytosis and increased levels of acute phase reactants. Magnetic resonance imaging of the hip, which was performed with the expectation of right hip pathology, revealed cellulitis and abscess in the right psoas muscle and associated inflammatory changes in the adjacent presacral fat plane but showed no abnormal lesions in the adjacent pelvic bone and spine. Staphylococcus hominis was cultured from the blood. With empirical antibiotic therapy, the patient recovered fully. We report a case of primary psoas abscess confused with hip pathology in an immunocompetent child without underlying disease.

Head and neck abscess usually requires hospitalization, intravenous antibiotic therapy, and surgical incision and drainage. Open surgical drainage may result in unsightly scars. We report two cases of a 56-year-old man with a facial abscess and a 47-year-old man with a parotid abscess. The patients were successfully treated with ultrasound-guided angiocatheter irrigation and drainage without scar. Ultrasound-guided angiocatheter irrigation and drainage can be a simple, safe and effective alternative procedure to open surgery in the management of the selected head and neck abscesses.

Usually fungal infections caused by opportunistic and pathogenic fungi had been an important cause of morbidity and mortality among immunocompromised patients. However clinical data and investigations for immunocompetent pathogenic fungal infections had been rare and neglected into clinical studies. Especially Cryptococcal brainstem abscess cases mimicking brain tumors were also much more rare. So we report this unusual case. This 47-year-old man presented with a history of progressively worsening headache and nausea for 1 month and several days of vomituritions before admission. Neurological and laboratory examinations performed demonstrated no abnormal findings. Previously he was healthy and did not have any significant medical illnesses. A CT and MRI scan revealed enhancing $1.8{\times}1.7{\times}2.0$ cm mass lesion in the left pons having central necrosis and peripheral edema compressing the fourth ventricle. And also positron emission tomogram scan demonstrated a hot uptake of fluoro-deoxy-glucose on the brainstem lesion without any evidences of systemic metastasis. Gross total mass resection was achieved with lateral suboccipital approach with neuronavigation system. Postoperatively he recovered without any neurological deficits. Pathologic report confirmed Cryptococcus neoformans and he was successively treated with antifungal medications. This is a previously unreported rare case of brainstem Cryptococcal abscess mimicking brain tumors in immunocompetent host without having any apparent typical meningeal symptoms and signs with resultant good neurosurgical recovery.

We present a patient who showed a sterile abscess after facial bone fixation with bioabsorbable plates and screws. He had zygomaticomaxillary complex and periorbital fracture due to falling down. The displaced bones were treated by open reduction and internal fixation successfully using bioabsorbable plate system. However, at postoperative 11 months, abrupt painless swelling was noted on the previous operation sites, left lateral eyebrow and lower eyelid. By surgical exploration, pus-like discharge and degraded materials were observed and debrided. The pathologic analysis revealed foreign body reaction with sterile abscess. This complication followed by bioabsorbable device implantation on maxillofacial bone surgery has been rarely reported in which we call attention to the maxillofacial plastic surgeons.

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.

Anoperineal tuberculosis is a rare extrapulmonary form of the disease and may present as abscess. We report a case of anoperineal tuberculous abscess, which showed low signal intensity on T1-weighted images, high signal intensity on T2-weighted images and diffusion restriction on diffusion weighted images.

Synchronous gastric cancer and adenomatous colorectal polyp in patients with Klebsiella pneumoniae-induced pyogenic liver abscess (KP-PLA) and bacteremia is a rare presentation. A 58-year-old man with a 6-month history of diabetes mellitus (DM) presented with febrile sensation and dull abdominal pain in the right upper quadrant of the abdomen. Subsequent to laboratory test results and abdominal computed tomography findings, KP-PLA with bacteremia was diagnosed. After intravenous antibiotic administration, his symptoms improved, and upper endoscopy and colonoscopy were performed to evaluate the cause of KP-PLA. Biopsy specimens of the prepyloric anterior wall revealed a moderately differentiated adenocarcinoma. Endoscopic mucosal resection of the colon revealed high-grade dysplasia. Early gastric cancer (EGC) and adenomatous colorectal polyps with high-grade dysplasia concomitant with KP-PLA and bacteremia were diagnosed in our patient who had DM. Intravenous antibiotic treatment for KP-PLA, subtotal gastrectomy for EGC, and colonoscopic mucosal resection for the colon polyp were performed. After 25 days of hospitalization, subtotal gastrectomy with adjacent lymph node dissection was performed. Follow-up ultrasound imaging showed resolution of the abscess 5 weeks post-antibiotic treatment, as well as no tumor metastasis. Upper gastrointestinal endoscopy and colonoscopy should be performed to evaluate gastric cancer in patients with PLA or bacteremia, accompanied with DM or an immunocompromised condition.

A retropharyngeal abscess is a rare disease entity in young infants but can develop after nasopharyngeal viral infection. Group B Streptococcus and Staphylococcus aureus are the most common pathogens in young infants, however, Mycobacterium tuberculosis is very rare. We report the case of retropharyngeal abscess and coinfection with S. aureus and M. tuberculosis in a very young infant presenting with respiratory symptoms due to upper airway obstruction. Usually tuberculous retropharyngeal abscesses are caused by the direct invasion of the bacteria from the spine via anterior longitudinal ligament of the spine. However, in this case, no associated spinal disease was observed.
