Gradenigo Syndrome in a 6-Year-Old Boy with Acute Otitis Media: A Case Report.

Gradenigo Syndrome (GS) is not a common intracranial complication of acute otitis media infections that needs proper diagnosis and management. This case report presents a 6-year-old child diagnosed with unilateral headache, right eye diplopia, and right abducens nerve palsy. MRI and cranial nerve examination facilitate the confirmation of GS. The patient was treated with proper antibiotics and showed good outcomes. This case report highlights the importance of early detection and understanding of the clinical picture associated with GS, which have a crucial role in achieving desired outcomes and avoiding serious complications.

Headache in Petrous Apicitis: A Case Report of Chronic Migraine-like Headache Due to Peripheral Pathology.

OBJECTIVE: To report a case of petrous apicitis that manifested as chronic migraine without aura and to discuss the pathophysiological mechanisms behind this presentation. BACKGROUND: Petrous apicitis is a rare complication of acute otitis media with varied clinical presentations that stem from the close proximity of the petrous apex to numerous neurovascular structures. Headache is among the common symptoms of petrous apicitis. METHODS: A case of new onset headache in the setting of petrous apicitis with symptomatic response to antibiotic therapy was reported. We provided a brief review of peripheral pathophysiological mechanisms of migraine and correlated to mechanism of headache in petrous apicitis. RESULTS: A 65-year-old man with chronic otitis externa/media presented with ongoing headache fulfilling International Classification of Headache Disorders 3rd edition (ICHD-3) criteria for chronic migraine without aura that persisted despite undergoing right mastoidectomy and tympanoplasty with multiple courses of oral antibiotic therapy for his chronic otitis. MRI brain revealed petrous apicitis, otomastoiditis, and clival osteomyelitis. His imaging findings improved and his migraine-like headache completely resolved after treatment with a prolonged course of antibiotics. CONCLUSIONS: Petrous apicitis can present as a headache with features of migraine, and in this case in particular, as chronic migraine without aura. The pathophysiological mechanisms that may underlie the generation of migraine-like headache in petrous apicitis may include the activation of nociceptive fibers within the periosteum of the petrous apex and clivus whose cell bodies originate in the trigeminal ganglion and upper cervical dorsal root ganglia. By treating the peripheral pathology, resolution of the headache may be achieved.

Gradenigo's syndrome with abscess of the petrous apex in pediatric patients: what is the best treatment?

BACKGROUND: Gradenigo's syndrome is defined by the classic clinical triad of ear discharge, trigeminal pain, and abducens nerve palsy. It has become a very rare nosological entity after the introduction of antibiotics, so that has been defined as the "forgotten syndrome." However, the underlying pathological process (apical petrositis) still represents a life-threatening condition that shall be immediately recognized in order to address the patient to the proper therapy. The therapy itself may be an argument of discussion: on a historical background ruled by surgery, reports of successful conservative antibiotic treatment have risen in recent years. METHODS AND RESULTS: We reported a case of Gradenigo's syndrome in a child with an abscess of the left petrous apex and initial involvement of the carotid artery. After multidisciplinary evaluation, we decided to encourage conservative treatment, until complete regression was observed. DISCUSSION: The available literature of the last 10 years was reviewed, with particular attention to the presence of an apical abscess and the therapeutic approach. The principles of management with regard to conservative therapy versus surgical indications are therefore examined and discussed.

Sudden Diplopia at a Pediatric Emergency Department: A Case of Gradenigo Syndrome in a Child.

OBJECTIVE: Otitis media, facial pain in trigeminal region, and ipsilateral abducens nerve palsy clinically define Gradenigo syndrome, a rare but serious complication of suppurative middle ear infection. Radiological investigation is required to confirm petrous apex involvement and to exclude further consequences as sinus thrombosis, meningitis, and intracranial abscess. METHODS/RESULTS: We report the case of an 8-year-old child referred to our emergency department for recurrent headache and sudden strabismus. Clinical evidence of suppurative otitis media raised the suspicion for Gradenigo syndrome, definitively confirmed at computed tomography and magnetic resonance imaging scans. Conservative treatment alone enabled complete clinical and radiological remission, without long-term sequelae. CONCLUSIONS: Despite being a rare condition, Gradenigo syndrome should be taken into account as potential differential diagnosis in children referred to emergency department for recurrent headache and strabismus. An accurate anamnesis to document recent ear infection is mandatory to orientate the diagnosis and focus radiological investigations. Early recognition and timely intervention may allow conservative management to succeed, avoiding the need for surgery and serious sequelae.

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.

The Forgotten Syndrome? Four Cases of Gradenigo's Syndrome and a Review of the Literature.

BACKGROUND: Gradenigo's Syndrome (GS) is defined as the clinical triad of acute otitis media, ipsilateral sixth nerve palsy, and pain in the distribution of the first and the second branches of the fifth nerve. The purpose of this study is to review the literature and report 4 cases of GS. METHODS: The study is a retrospective case series and a review of the literature. Four consecutive patients (aged 5-70 years) treated by otolaryngologists and ophthalmologists for GS in the Capital region of Denmark from 2003 to 2015 are presented. Diagnosis is based on the clinical triad, and in 3 of 4 patients, neuroimaging supports the diagnosis. Follow-up was continued until both the sixth nerve palsy and the ear infection had resolved. Diagnostic work-up and treatment profile are described. RESULTS: In 3 of our 4 reported patients, the presentation of GS was classic with a history of acute otitis media and ipsilateral sixth nerve palsy. One case presented as a chronic case with a sixth nerve palsy secondary to chronic suppurative otitis media (CSOM), with a relapse 6 years later. CONCLUSION: GS is a rare and potentially life-threatening complication to otitis media. GS can present in an acute and chronic form, and should be a differential diagnosis in the workup of unexplained sixth nerve palsy.

[Diagnosis and treatment of the complications of otitis media in adults. Case series and literature review]. / Abordaje diagnóstico y terapéutico de las complicaciones de la otitis media en el adulto. Serie de casos y revisión de la literatura.

BACKGROUND: The complications of otitis media (intra-cranial and extra-cranial) used to have a high morbidity and mortality in the pre-antibiotic era, but these are now relatively rare, mainly due to the use of antibiotics and the use of ventilation tubes, reducing the incidence of such complications significantly. Currently, an early suspicion of these complications is a major challenge for diagnosis and management. CLINICAL CASES: The cases of 5 patients (all male) are presented, who were diagnosed with complicated otitis media, 80% (4) with a mean age of 34.6 years (17-52). There was major comorbidity in 60% (3), with one patient with diabetes mellitus type 2, and two with chronic renal failure. There were 3 (60%) intra-cranial complications: one patient with thrombosis of the sigmoid sinus and a cerebellar abscess; another with a retroauricular and brain abscess, and a third with meningitis. Of the 2 (40%) extra-cranial complications: one patient had a Bezold abscess, and the other with a soft tissue abscess and petrositis. All patients were managed with surgery and antibiotic therapy, with 100% survival (5), and with no neurological sequelae. The clinical course of otitis media is usually short, limiting the infection process in the majority of patients due to the immune response and sensitivity of the microbe to the antibiotic used. However, a small number of patients (1-5%) may develop complications. CONCLUSION: Otitis media is a common disease in our country, complications are rare, but should be suspected when the picture is of torpid evolution with clinical worsening and manifestation of neurological signs.

Aspergillus petrous apicitis associated with cerebral and peritubular abscesses in an immunocompetent man.

BACKGROUND: Petrous apex aspergillosis is an uncommon and dangerous condition, with only four previously reported cases. As with other forms of petrous apicitis, the clinical symptoms are often non-specific and this contributes to diagnostic delay. This paper presents the first reported case of Aspergillus petrous apicitis associated with an intracranial or nasopharyngeal abscess. CASE REPORT: A 72-year-old man with chronic otorrhoea developed neuralgic headaches and progressive lower cranial nerve palsies despite antibiotic therapy. Imaging revealed petrous apicitis, a temporal lobe abscess and nasopharyngeal abscess. Analysis of biopsy tissue indicated invasive aspergillosis. The patient recovered on a protracted course of voriconazole in addition to medium-term antibiotic therapy. CONCLUSION: Invasive fungal disease should be considered early in the course of skull base osteomyelitis that is clinically unresponsive to empirical broad spectrum antibiotics. This paper highlights the role of tissue biopsy in diagnosis, and the efficacy of voriconazole therapy without the need for radical surgery.

Subacute tuberculous otitis media complicated by petrositis and meningitis.

AIMS: The aim of our case study is to illustrate diagnostic and therapeutic difficulties as well as gravity related to tuberculous otitis media with intracranial complications. CASE PRESENTATION: A diabetic male patient of 65 years old was treated for subacute otitis media with mixed hearing loss. Early bacteriologic samples from ear exudates revealed opportunistic pathogens. Clinical evolution after four months was marked by the appearance of mastoiditis with facial paralysis. The patient presented petrositis and bilateral laryngeal paralysis with lymphocytic meningitis after six and eight months respectively. Tuberculosis was suspected after a positive ELlspot tests with appearance of biologic markers of hepatic dysfunction like cholestasis and hepatic cytolysis. Although antituberculous treatment was instaured even without isolation of acid fast bacilli, the patient died after ten months. CONCLUSION: Subacute otitis media complicated by labyrinthitis, early onset of facial paralysis or any other oranial nerve palsy should raise suspicion of tuberculosis. The prognosis depends on early diagnosis which remains difficult despite morphological and metabolic imaging. The diagnostic workup should include histological and bacteriologic samples, liver markers of intacellular damage as well as ELlspot test. The prognosis remains poor especially in immunocompromised patients despite appropriate treatment.

Conservative management of Gradenigo's syndrome in a child.

Gradenigo's syndrome, the triad of suppurative otitis media, abducens nerve palsy and pain in the ophthalmic division of the trigeminal nerve, remains a rare complication of otitis media. A case in a paediatric patient is described, successfully managed conservatively. There is little evidence to support increased use of antibiotics in acute otitis media to prevent this complication.
