We describe a unique presentation of acute myeloid leukaemia (AML) with myeloid sarcoma (MS), manifested as proptosis with multiple cranial nerve palsies in a 9-year-old boy. MRI of the brain revealed multiple enhancing lesions and bilateral mastoiditis, in addition to sagittal sinus thrombosis. Peripheral blood smear demonstrated blasts showing Auer rods. Bone marrow examination confirmed the diagnosis of AML. PCR was positive for RUNX1-RUNX1T1. Neurological deficits improved with induction chemotherapy for AML...

Septic arthritis of the temporomandibular joint as a complication of acute otitis media is rare in the Western world. This report describes the case of a 7-year-old boy who had pain in his right ear and limited mouth opening, following the onset of acute otitis media. A contrast-enhanced computed tomography scan revealed right-sided mastoiditis and hydrops of the right temporomandibular joint, suggesting septic arthritis. Real-time PCR and microbiologic analysis identified Streptococcus pyogenes and Staphylococcus epidermidis in the joint aspirate...

HYPOTHESIS: The temporal bone shows regional differences in bone development. BACKGROUND: The spreading pattern of acute mastoiditis shows age-related differences. In infants, it spreads laterally and causes retroauricular swelling, whereas in older children, it tends to spread medially and causes intracranial complications. We hypothesized that bone maturation may influence the spreading pattern of acute mastoiditis. METHODS: Eighty participants with normal hearing, aged 3 months to 42 years, participated in this study...

BACKGROUND: Acute mastoiditis remains the commonest intratemporal complication of otitis media in the paediatric population. There has been a lack of consensus regarding the diagnosis and management of acute mastoiditis, resulting in considerable disparity in conservative and surgical management. OBJECTIVES: To review the current literature, proposing recommendations for the management of paediatric acute mastoiditis and appraising the treatment outcomes. METHOD: A systematic review was conducted using PubMed, Web of Science and Cochrane Library databases...

Intracranial infections may result from contiguity, such as mastoiditis or acute otitis media, or from haematogenous dissemination from an infectious source. Streptococcus constellatus, a coccus from the normal genital, oral and gastrointestinal flora, has a tendency to form abscesses, but not to cause infective endocarditis (IE). Also, S. constellatus is an extremely rare causative agent of brain abscess. We report the case of a woman with a colorectal tumour who presented with IE and cerebellar abscesses due to a S...

PURPOSE: To assess the usefulness of the new computed tomography (CT) classification criteria proposed by Horowitz et al. and their effect on inter-observer agreement when estimating intracranial complications of acute mastoiditis. METHODS: In this study 53 contrast-enhanced CT scans of patients with acute mastoiditis were each retrospectively reviewed by two radiologists, using two different assessment criteria for intracranial complications. According to the new criteria, intracranial CT findings in the perisinuous area were graded into four classes (I normal, II linear halo, III nodular halo ≤4 mm thick and IV nodular halo >4 mm thick), where classes III and IV indicate a high risk for epidural abscesses...

Rebecca Ichord
Cerebral sinovenous thrombosis (CSVT) is a rare but serious cerebrovascular disorder affecting children from the newborn period through childhood and adolescence. The incidence is estimated at 0.6/100,000/year, with 30-50% occurring in newborns. Causes are diverse and are highly age dependent. Acute systemic illness is the dominant risk factor among newborns. In childhood CSVT, acute infections of the head and neck such as mastoiditis are most common, followed by chronic underlying diseases such as nephrotic syndrome, cancer, and inflammatory bowel disease...

BACKGROUND: Pneumococcal conjugate vaccine (PCV) was introduced in 2000. The first 7-valent vaccine (PCV7) was followed by a 13-valent vaccine (PCV13) with the same conjugate, and a 10-valent vaccine (PCV10), conjugated to protein D from Haemophilus influenzae. The vaccines offer some protection against pneumococcal acute otitis media (AOM), and, with PCV10, possibly also some protection against H. influenzae AOM. PCV7 was introduced in Sweden in 2009, but from 2010, Swedish counties were free to use either PCV13 or PCV10...

Metastatic renal cell carcinoma (RCC) involving the temporal bone is a rare entity. It is usually asymptomatic and misdiagnosis as acute otitis media, mastoiditis, and Ramsay-Hunt syndrome in early onset is not uncommon. We report a case of RCC metastasis to the postoperative temporal bone in the middle of molecular targeted therapy. A 60-year-old man presented left facial palsy with severe retro-auricular pain and he also underwent left middle ear surgery for cholesteatoma more than 30 years before and had been aware of discontinuous otorrhea; therefore, initially we speculated that facial palsy was derived from recurrent cholesteatoma or Ramsay-Hunt syndrome...

INTRODUCTION: Petrositis is a rare but severe complication of acute otitis media and mastoiditis. Despite efficient antibiotic therapy, there are still reports of both intratemporal and intracranial complications of otitis media with the potential risk of high morbidity and mortality. Petrositis has traditionally been treated with surgery, but recent advances in imaging, with improved antibiotic treatment, allow more conservative management. CASE REPORT: In this case report we describe the clinical course and treatment of a 33-year-old man with petrous apicitis who presented with severe otalgia, retro-orbital pain, and sixth cranial nerve palsy Gradenigo syndrome...

This article was designed to report a case of otogenic abscess of the temporomandibular joint in a 5 year-old child. The specific feature of this observation is a rare complication of acute otitis media (otogenic abscess of the temporomandibular joint). Of crucial importance for the establishment of the correct diagnosis was the timely evaluation of the state of the temporomandibular bones by means of CT examination.

BACKGROUND: Acute otitis media (AOM) is a common childhood infection, which is usually managed in the outpatient setting. Yet, the more severe cases are referred for inpatient treatment. We hypothesized that pneumococcal conjugate vaccines (PCVs), administered during the first year of life, would decrease AOM admissions rate in this age group. We studied the characteristics of infants admitted with AOM and acute mastoiditis (AM) in the PCV13 era, routinely given from November 2010 to all infants...

Acute otitis media used to cause fatal results because of its intracranial complications before the introduction of potent and effective antibiotics. After the introduction of antibiotics, complications have started to be observed more frequently as a result of chronic otitis media and especially in children. Because clinical findings changed and became indistinct, the diagnosis of otitis and mastoiditis has been made occasionally with imaging findings only after complications occurred. Multidetector computed tomography and magnetic resonance imaging are efficient and sufficient methods in the rapid diagnosis and should be immediately referred methods...

When acute mastoiditis occurs in cochlear implant recipients, it can progress to subsequent retroauricular abscess due to the absence of the external mastoid cortex resulting from mastoidectomy performed for cochlear implantation. The management goal is to control infection while preserving the implanted device. A 2-year-old boy with cochlear implants developed acute mastoiditis and a subsequent retroauricular abscess. The patient underwent a surgical intervention based on the diagnosis made utilizing gray-scale and power Doppler sonography...
