Pediatric head and neck emergencies.

PURPOSE: Head and neck emergencies in children are frequent cause of visits to the hospital. Imaging plays a critical role in the management of these patients. This review article aims to familiarize radiologists with the common clinical presentations encountered, imaging characteristics of nontraumatic pediatric head and neck emergencies, and improve their ability to recognize associated complications as well as be aware of common mimics. METHODS: We researched our database for commonly encountered nontraumatic head and neck emergencies in children. A literature search was done to compare and complete the list of conditions to be discussed in this review. RESULTS: The review was organized according to anatomical location of the emergent condition. Relevant anatomy has been discussed along with clinical presentation, imaging characteristics and complications. We have presented common mimics with each set of disorders. Key imaging characteristics have been delineated using radiology images. CONCLUSION: Familiarity with the known complications of head and neck emergencies allows the radiologist to actively search for such findings, encourage early institution of appropriate therapy, and improve outcomes.

Petrositis caused by fluconazole-resistant candida: case report and literature review.

BACKGROUND: Petrositis is a rare and fatal complication associated with otitis media. It is most likely caused by bacterial infections, but in some cases it is caused by fungal infections. CASE STUDY: The case in this report is associated with fungal petrositis. The clinical symptoms are: ear pain from chronic otitis media, severe headache, peripheral facial palsy and diplopia. The case was finally confirmed through imaging of middle ear, bacterial culture, pathology, and blood Metagenomic next-generation sequencing (mNGS) test. The patient was treated with sensitive antifungal drugs. CONCLUSION: Drug treatment is conservative but efficient method in this case. mNGS can provide pathogenic reference, when antibiotic is not efficient enough for fungal infections or drug-resistant fungal infections cases. This allows we to adjust drug use for the treatment.

A child with Gradenigo syndrome presenting with meningism: a case report.

BACKGROUND: The symptoms of meningitis which include fever, headache, photophobia and irritability along with abducens nerve palsy pose a diagnostic dilemma requiring urgent attention. Here we report how such a dilemma was methodically and sequentially resolved using anatomical knowledge supported by neuroimaging and the eventual diagnosis of Gradenigo syndrome was made. CASE PRESENTATION: A 6-year-old previously healthy boy from Sri Lanka presented with high grade fever, headache, photophobia and left eye pain for 10 days and diplopia for 2 days duration. Neurological examination was unremarkable except for left sided abducens nerve palsy. He had high inflammatory markers and white blood cell count. A tentative differential diagnosis of acute bacterial meningitis complicated by cerebral oedema, acute hydrocephalus or cerebral abscess was made. However, non-contrast CT brain, cerebrospinal fluid analysis and electroencephalogram were normal leading to a diagnostic dilemma. MRI brain with contrast performed 3 days later due to limited resources revealed left mastoiditis extending to petrous temporal bone confirming Gradenigo syndrome. CONCLUSION: This case report highlights the importance of a thorough physical examination in children presenting with unrelated neurological symptoms and signs. Unilateral abducens nerve palsy raises the suspicion of increased intracranial pressure and neuroimaging is vital in diagnostic uncertainties. Gradenigo syndrome emphasises the importance of incorporating anatomical knowledge into clinical practice.

Gradenigo's syndrome: A common infection with uncommon consequences.

Acute otitis media is a common diagnosis encountered by emergency medicine providers. With appropriate antibiotic treatment, patients with otitis media, in general, have minimal long-term sequela from their underlying infection (Limb et al., 2017 [1]). However, untreated cases can develop life-threatening complications that require prompt intervention. We report a case of an 8-year-old that developed Gradenigo's syndrome, a condition characterized by the triad of otitis media, facial pain in the distribution of the trigeminal nerve, and abducens nerve palsy (Yeung and Lustig, 2016; Janjua et al., 2016; Kantas et al., 2010; Motamed and Kalan, n.d.; Vita Fooken Jensen et al., 2016 [2-6]). Signs and symptoms are often subtle, so a high-level of suspicion is required in order not to miss this potentially fatal process.

Atypical Gradenigo's syndrome in a pediatric case: A critical review of neuroimaging.

Gradenigo's syndrome, a rare but serious complication of otitis media, encompasses a triad of symptoms including otalgia, facial palsy, and abducens nerve palsy, pointing to the involvement of the petrous apex. This case report presents an 11-year-old boy with an atypical manifestation of Gradenigo's syndrome, characterized by the absence of classic features such as abducens nerve palsy and purulent otorrhea. MRI findings were significant for petrous apicitis extending to Meckel's cave and the cavernous sinus, along with abscess formation and clivus osteomyelitis. The report highlights the critical role of advanced neuroimaging, particularly MRI, in the diagnosis and management of this condition. It underscores the importance of recognizing atypical presentations of Gradenigo's syndrome and the effectiveness of imaging-guided conservative treatment strategies in pediatric otological cases.

Refractory Pseudomonas Osteomyelitis of the Skull Base With Gradenigo's Syndrome: Early Dysphagia and Late Abducens Nerve Palsy.

Gradenigo's syndrome (GS) is a rare entity characterized by otitis media, pain in the trigeminal nerve distribution and abducens nerve palsy. The classic triad is uncommon, making the diagnostic workup challenging. Specifically, the diagnostic approach includes medical history, a complete otorhinolaryngological examination, a pure-tone audiogram and radiological investigation such as contrast-enhanced computed tomography scan and magnetic resonance imaging of head and neck. Broad-spectrum antibiotics are the first-line treatment, such as intravenous (IV) ceftriaxone and IV metronidazole. Here, we present the case of a 71-year-old man with a previous history of otitis media and poorly controlled type 2 diabetes mellitus. He presented to our attention with facial pain, left hemilarynx paralysis, dysphagia and otorrhea. The patient was treated with broad-spectrum antibiotics without any clinical improvement. Imaging evaluations demonstrated the presence of wide and poorly defined pathological material with epicenter in the masticatory space, involving all nearby structures. The patient underwent multiple biopsies without obtaining a definitive tissue diagnosis of neoplasia. After 2 months, the patient developed delayed VI cranial nerve palsy, providing evidence of GS. Although incomplete, GS has been described in the literature; however, none of the cases exhibited a latent abducent deficit. To the best of our knowledge, this is the only case with a delayed onset of abducens nerve palsy.

Insights into Gradenigo syndrome: Case presentation and review.

Gradenigo syndrome (GS) is characterized by a triad of clinical features: abducens nerve palsy, retro-orbital pain, and otorrhea, arising as a complication of suppurative otitis media. Herein, we present a case of GS in a 15-year-old male patient, secondary to left otitis media. The patient exhibited fever, otorrhea, accompanied by diplopia, retrobulbar pain, and headache. Imaging studies demonstrated petrous bone destruction and inflammatory changes with opacification of petrous bone, mastoid cells and surrounding structures, confirming the diagnosis of GS. Treatment included intravenous antibiotics and anticoagulants, resulting in the resolution of symptoms and radiological improvement. GS, though rare, warrants prompt recognition and appropriate management to prevent severe complications. Diagnostic imaging plays a crucial role in evaluation, and treatment often involves prolonged antibiotic therapy and, in severe cases, surgical intervention. Understanding the clinical presentation and management strategies is essential for clinicians encountering this condition.

A Case of Gradenigo's Syndrome in an Elderly Patient.

Gradenigo's syndrome (GS) presents with the classical triad of otitis media, facial pain, and abducens nerve palsy as a complication of petrous apicitis. However, in the era of increased antibiotic use, complications of petrous apicitis have become infrequent and cases of GS are not frequently seen in clinical practice. We present the case of a 76-year-old man with uncontrolled diabetes mellitus presented with a two-month history of worsening right-sided headache, right-sided facial pain and weakness, along with dysphagia, hearing loss, and right otalgia with intermittent otorrhea following a right upper molar extraction. Imaging identified the inflammatory changes and indications of petrous apicitis. Although GS has become quite rare in recent years, this case highlights the importance of the responsible use of antibiotics in treating a seemingly innocuous infection.

Gradenigo Syndrome: A Case Report of a Rare Complication of Otitis Media.

Otitis media, a common inflammation of the middle ear, frequently complicates upper respiratory infections. Gradenigo's syndrome, a rare complication, manifests as suppurative otitis media, abducens nerve palsy, and severe trigeminal nerve pain. Prompt recognition is vital because of the proximity of the infection to critical neurovascular structures. We present the case of a 38-year-old female who presented with facial pain, otalgia, and diplopia following an upper respiratory infection. Examination revealed facial weakness and abducens nerve palsy. Laboratory results showed elevated inflammatory markers. Imaging confirmed middle ear involvement. Antibiotics were initiated, and myringotomy was performed, resulting in a successful outcome. This case report contributes to understanding Gradenigo's syndrome's clinical nuances, emphasizing the necessity of a structured diagnostic and therapeutic approach. Ongoing research is crucial for refining diagnostic criteria, optimizing treatment, and enhancing pathophysiological understanding. Increased medical education is imperative to ensure early detection and improved patient outcomes.

Neurosurgical Intervention in the Treatment of Gradenigo Syndrome: A Case Report.

Gradenigo syndrome comprises a clinical triad: retro-orbital pain, sixth cranial nerve palsy, and purulent otorrhea. This clinical syndrome often arises secondary to petrous apicitis, which is an infection of the petrous apex that may result from the contiguous spread of infection from the ear or mastoid. This syndrome is very rare, and based on the existing literature, the initial approach for treatment involves long-term administration of IV antibiotics, which may resolve the underlying infection related to petrous apicitis, mastoiditis, and/or otitis media. In this case, the patient, a 69-year-old male, had a progression of several symptoms, including recurrent headaches, diplopia, hearing loss, and dysphagia, despite long-term antibiotic therapy and a prior mastoidectomy. Thus, the neurosurgical team decided to intervene via anterior petrous bone resection via the Kawase approach, which unfortunately did not result in the resolution of the patient's symptoms. The patient continued to have symptoms of Gradenigo syndrome, including sixth cranial nerve palsy and was subsequently referred to outpatient follow-up for further management. In this report, we present the patient's case and a brief review of the literature concerning various treatment modalities for Gradenigo syndrome.

Gradenigo's Syndrome and Vernet Syndrome as Presenting Signs of Nasopharyngeal Carcinoma.

Both Gradenigo's syndrome and Vernet syndrome are rare pathologies of the intracranial space; both involve compression of a particular anatomic location in the skull, thus affecting structures nearby or within that space. A patient presenting with one or both of these syndromes should raise concern for malignancy, head trauma, or an intracranial infection. We present a case of a 39-year-old female with three weeks of left-sided ear, face, and neck pain along with difficulty swallowing and reduced vision in the left eye. Magnetic resonance imaging of the brain revealed fullness in the left nasopharyngeal region, raising concern for malignancy or infection. Biopsy of the mass ultimately revealed Epstein-Barr virus positive nasopharyngeal carcinoma, nonkeratinizing undifferentiated type, along with culture data revealing methicillin-resistant Staphylococcus aureus positive left otomastoiditis. She received chemoradiation therapy along with six weeks of antibiotic therapy. A patient presenting with symptoms reflective of a sinus infection unrelieved by antibiotics with concomitant cranial nerve deficits should raise clinical concern for an intracranial pathology rather than a simple case of sinusitis.

Gradenigo's Syndrome With Septic Lateral Sinus Thrombosis.

Gradenigo's syndrome (GS) is a rare but life-threatening complication of acute otitis media (AOM). It is classically defined as a clinical triad of acute otitis media, ipsilateral sixth (abducens) nerve palsy, and pain in the distribution of the first and second branches of the trigeminal nerve. Another rare but serious complication of AOM is venous sinus thrombosis, which is often associated with GS. The diagnosis of these conditions requires clinical suspicion, sound interpretation of signs and symptoms, and the use of the correct imaging techniques. Here, we present the case of an 81-year-old man with a previous history of recurrent otitis media, who presented with GS and septic lateral sinus thrombosis. The clinical presentation, physiopathology, and management of these conditions are discussed.

Anatomy and Pathology of the Skull Base: Malignant and Nonmalignant Lesions.

The skull base (SB) is the osseous foundation of the cranial vault. It contains many openings that allow communication between the extracranial and intracranial structures. This communication is crucial in normal physiologic processes yet may also arrow spread of disease. This article provides a comprehensive review of SB anatomy including important landmarks and anatomic variants relevant to SB surgery. We also illustrate the diverse pathologies affecting the SB.

Atypical Gradenigo Syndrome in an Elderly Man Resolved with Mastoidectomy and Petrous Apicectomy.

Gradenigo syndrome (GS) was described primarily in the paediatric population, especially in the pre-antibiotic era. GS is rarely reported in the elderly population, especially in the post-antibiotic era. We present the rare case of a 67-year-old man who presented with an incomplete triad of symptoms (without abducens nerve palsy) of GS that failed medical therapy and was successfully treated with surgical intervention (mastoidectomy and petrous apicectomy). Physicians should be familiar with atypical presenting symptoms of GS as it can lead to life-threatening complications, especially in the elderly. GS cases resistant to medical therapy may require prompt appropriate imaging studies and surgical intervention. LEARNING POINTS: Gradenigo syndrome may present with an incomplete triad (without abducens nerve palsy), especially in the post-antibiotic era.Gradenigo syndrome can rarely affect immunocompromised elderly patients.Gradenigo syndrome cases resistant to medical therapy may require prompt appropriate imaging studies and surgical intervention (mastoidectomy and petrous apicectomy).

Case Report: Diagnosis of Petrous Apex IgG4-Related Disease by Middle Cranial Fossa Craniotomy and Temporal Bone Biopsy.

Introduction: Primary IgG4-related disease (IgG4-RD) of the temporal bone is a rare condition. Unlike typical petrous apicitis or Gradenigo syndrome, our patient presented exclusively with unilateral cranial nerve VI palsy and symptoms of diplopia. Skull base imaging demonstrated a destructive bony lesion in the petrous apex. Imaging and systemic investigations were insufficient to support a diagnosis. The diagnosis was achieved histologically after acquiring the specimen by middle cranial fossa craniotomy and temporal bone biopsy. This case report is thought to be the first published description of a diagnosis of IgG4-RD proven with the middle cranial fossa approach. Case Report: We describe a 29-year-old female with primary IgG4-RD of the petrous apex of the temporal bone. This patient presented with a few-month history of left-sided headache and recent-onset diplopia due to paralysis of cranial nerve VI. Imaging demonstrated a petrous apex lesion, and comprehensive systemic investigations could not reach a diagnosis. A middle cranial fossa craniotomy and a biopsy of the temporal bone lesion were undertaken to establish the diagnosis. Histological confirmation of IgG4-RD was proven. Following treatment with corticosteroids, the patient experienced complete recovery and resolution of her symptoms. Conclusion: This study describes a case of primary IgG4-RD of the petrous apex of the temporal bone that presented with diplopia and was diagnosed by middle fossa craniotomy and temporal bone biopsy. To the best of our knowledge, this is the first case description where primary diagnosis was made based on middle cranial fossa craniotomy and temporal bone biopsy.

Steroid-Responsive Gradenigo's Syndrome Mimicking Subdural Hematoma.

Gradenigo's syndrome (GS) is featured by a clinical triad of otorrhea, retro-orbital pain, and a sixth nerve palsy. Clinical examination is crucial prior to considering neuroimaging. The majority of cases are secondary to infection thus requiring long-term broad-spectrum antibiotics; severe cases also require surgical intervention for risk of intracranial abscess or even death. The patient was a 35-year-old female who presented with right temporal headache and right retro-orbital pain. The initial diagnosis from the local clinic was of subdural hemorrhage. Cranial nerve (CN) VI paresis was noted upon examination and inflammatory process was documented based on brain MR. The patient was diagnosed with Gradenigo's syndrome and administered antibiotics and steroids. Symptoms recurred after cessation of steroids and once antibiotics-related fever developed. The symptoms resolved after stopping the antibiotics and reintroducing steroids. The MRI performed after three months recorded no brain inflammation. We report a Gradenigo's syndrome caused by chronic inflammation with good response to steroids. To our best knowledge, there were merely approximately 80 patients who were reported with Gradnigo or Gradenigo's syndrome before. Infection comprised 76% of cases, thus broad-spectrum and long-term antibiotics use have been emphasized instead of steroid use. However, steroids also play an important role in reducing nerve injury by edematous change.

An unusual case of acute otitis media resulting in Gradenigo syndrome: CT and MRI findings.

With the widespread use of antibiotics, Gradenigo syndrome is a rare complication of acute otitis media (AOM) and acute mastoiditis. It is an uncommon form of petrous apicitis and can be life-threatening. We report the case of a 14-year-old female with unresolved AOM, who developed otorrhea, ipsilateral headaches, diplopia and raised inflammatory markers. Magnetic Resonance Imaging (MRI) demonstrated features of petrous apicitis and confirmed the suspicion of Gradenigo syndrome. The objective of this clinical case report is to highlight this unusual syndrome together with its radiological appearance to improve its diagnosis and management.

How well do we know Gradenigo? A comprehensive literature review and proposal for novel diagnostic categories of Gradenigo's syndrome.

Gradenigo's Syndrome is a rare complication of otitis media and/or mastoiditis resulting in inflammation of the petrous apex of the temporal bone. Here, we highlight an interesting case from our institution, summarize available pediatric cases from the past fifty years to provide an updated diagnostic categorization for this rare condition with confusing nomenclature, and suggest guidance for diagnosis and management.

Delayed diagnosed Gradenigo's syndrome associated with acute otitis media.

Gradenigo's syndrome presents as a triad of retroorbital pain, ipsilateral abducens palsy, and purulent otorrhea. If the otologic pathologies in Gradenigo's syndrome go unnoticed, the condition could be misdiagnosed with neurological diseases because of retroorbital pain and abducens palsy. Treatment of Gradenigo's syndrome remains controversial. Although some reports state that long-term antibiotic treatment is sufficient, we recommended that management ought to be guided on a case-by-case basis depending on patient and disease factors. Herein, we report a delayed diagnosed pediatric case of Gradenigo's syndrome associated with acute otitis media that was treated with ventilation tube insertion.
