BACKGROUND AND OBJECTIVES: Diagnostic features of peritonsillar abscess are an asymmetrically enlarged palatine tonsil with peripheral rim enhancement and central low density in the post-contrast computed tomography (CT). Although it is necessary to differentiate tumorous conditions of tonsils to compare pre- and post-contrast CT, pre-contrast CT may be less useful in the diagnosis of peritonsillar abscess. This study aims to evaluate of the efficacy of single post-contrast CT for diagnosis and treatment of peritonsillar abscess. SUBJECTS AND METHOD: We retrospectively compared 29 patients with peritonsillar abscess, who were diagnosed by single post-contrast CT, with 36 patients diagnosed by pre- and post-contrast CT to determine the success rates of pus drainage and hospital days. Additionally, two otorhinolaryngologists made a judgment of abscess presence for sixty randomly mixed CT images of peritonsillar abscess or tonsillitis with pre- and post-contrast CT or single post-contrast CT. RESULTS: There were no significant differences in the success rate of drainage (p=0.622) and hospital days (p=0.504) between groups with/without pre-contrast CT. Abscess presence was judged by raters with/without pre-contrast CT. Inter-rater agreement value (Cohen's kappa) was 0.825 (p<0.01). CONCLUSION: Single post-contrast CT of peritonsillar abscess may be a good alternative for diagnosis and treatment and may reduce unnecessary exposure to radiation.

BACKGROUND AND OBJECTIVES: Abscess of neck is a life-threatening disease in children. Detection of abscess is important because it is essential for the determination of surgical drainage. However, clinical diagnosis is difficult, because children are seldom able to verbalize their symptoms or cooperate with physical examination. This study aims to review the clinical characteristics of 157 pediatric patients with neck inflammation and investigate the relative risk factors for abscess. SUBJECTS AND METHOD: Pediatric patients who were admitted to Dongguk University Hospital from January 2005 to July 2014 with acute neck inflammation were reviewed. All 157 pediatric patients were divided into two groups, based on radiologic findings with and without neck abscess. RESULTS: Of 157 patients, 53 children were diagnosed with neck abscess, and peritonsillar abscess was the most common type of neck abscess followed by submandibular abscess, retro·parapharyngeal abscess and posterior triangle & other abscess. The dominant pathogens, staphylococcal infection (≤2 yr) and streptococcal infection (>3 yr), was different for the different age group. The abscess group except for peritonsillar abscess was characterized by younger age, higher heart rate and WBC count, and longer hospital days than those without abscess (p=0.026, 0.026, <0.001, 0.007 respectively). Multivariate analysis revealed younger age (≤24 mo) and higher heart rate were independent predictors for abscess formation (odds ratio: 3.022, 2.923). CONCLUSION: Pediatric patients with high heart rate & younger age are at risk for abscess formation; meticulous care and early imaging work up are required in younger children with deep neck infection, and especially with higher heart rate.

Lemierre's syndrome is very rare and is characterized by previous oropharyngeal infections, such as pharyngitis or peritonsillar abscess, leading to high fever, internal jugular venous thrombosis, and metastatic infections to multiple internal organs. Prompt and accurate diagnosis followed by early treatment with antibiotics is very important because its mortality is high if treatment is delayed. We report on the case of a 23-year-old female who was transferred to our hospital with a left peritonsillar abscess combined with left jugular venous thrombosis, complaining of a sore throat and left submandibular swelling, and diagnosed as Lemierre's syndrome. Finally, she was treated successfully without anticoagulants.

Peritonsillar abscess is a common deep throat infection. Early diagnosis and prompt, appropriate management of a peritonsillar abscess prevents mortality. A 45-year-old woman on steroids for an ulcerative colitis (UC) exacerbation presented with sore throat and multiple skin ulcers on her left forearm and right foot. Computed tomography of the neck revealed a peritonsillar abscess. Gram staining and culture of the abscess were negative, and a skin biopsy suggested pyoderma gangrenosum (PG). The final diagnosis was peritonsillar involvement of steroid-refractory PG-associated UC. The patient showed a complete response to infliximab. Here, we report a case of successful infliximab treatment for peritonsillar involvement of steroid-refractory PG-associated UC.

Kawasaki disease (KD) causes multisystemic vasculitis but infrequently manifests with deep neck infections, such as a peritonsillar abscess, peritonsillar or deep neck cellulitis, suppurative parapharyngeal infection, or retropharyngeal abscess. As its etiology is still unknown, the diagnosis is usually made based on typical symptoms. The differential diagnosis between KD and deep neck infections is important, considering the variable head and neck manifestations of KD. There are several reports on KD patients who were initially diagnosed with retropharyngeal abscess on on computed tomography scans (CT). However, the previously reported cases did not have abscess or fluid collection on retropharyngeal aspiration. Therefore, false-positive neck CT scans have been obtained, until recently. In this case, suspected neck abscess in patients with KD unresponsive to intravenous immunoglobulin could signal the possible coexistence of suppurative cervical lymphadenitis.

Gossypiboma is the term used to describe mass lesion caused by retained surgical sponges with reactive tissue after a surgical intervention. This condition has been mostly reported after abdominal or thoracic surgery. We recently experienced a case of gossypiboma of the peritonsillar space in a 31-year old male patient, who previously undergone incision and drainage for treatment of peritonsillar abscess but had persistent symptom of sore throat, myalgia and febrile sensation for 6 months. The gauze was accidently left in the peritonsillar space after a surgical intervention and resulted in mass like lesion in the ipsilateral peritonsillar space. To our knowledge, this is the first case of oropharyngeal gossypiboma in the literature. Although it is rare in adults, foreign body of peritonsillar space should be considered in the differential diagnosis of unilateral recurrent tonsillitis.

A peritonsillar abscess is one of the most commonly occurring deep space infections of the head and neck in adults and children. A peritonsillar abscess that appears in newborns, however, is extremely rare. The treatment of a peritonsillar abscess requires both the selection of appropriate antibiotics and the best procedure to remove the abscessed material. We report a case of a peritonsillar abscess in a 40-day-old infant who was treated with antibiotic therapy alone.

Kawasaki disease is an acute febrile mucocutanenous syndrome associated with multisystemic vasculitis. The etiology of Kawasaki disease is still unknown therefore this disease can be diagnosed only based upon clinician's recognition of a symptom pattern which includes high fever, oral cavity changes, polymorphous skin rash, conjuctival injections, cervical lymphadenopathy, and swelling of peripheral extremities. Early diagnosis and treatment of Kawasaki disease is critical to reduce the risk of cardiac complications such as coronary aneurysm. However there is no specific diagnostic tools for Kawasaki disease, unusual clinical manifestation resembling infectious disease involving cervical lesion often leads to delay in appropriate diagnosis and treatment of Kawasaki disease. We report a ten-year-old girl with Kawasaki disease whose initial presentation mimicking peritonsillar abscess.

Arcanobacterium haemolyticum is a cause of chronic skin ulcers in diabetic patients and respiratory infection, especially pharyngitis in healthy person. Less frequently, it is a cause of osteomyelitis, meningitis, pneumonia, abscess, endocarditis and sepsis. We isolated A. haemolyticum from 5 patients including foot or back ulceration in 3 diabetic patients, wound on calcaneus in a chronic osteomyelitis patient and peritonsillar abscess in a pharyngitis patient. A. haemolyticum is usually isolated with other microorganisms and coryneform bacilli which are often considered to be nonpathogenic normal flora or contaminants in wound infections. The correct diagnosis of this microorganism is important for proper treatment and prevention of serious infections.
