Delayed otogenic hydrocephalus after acute otitis media in pediatric patients: the changing presentation of a serious otologic complication.

CONCLUSIONS: The clinical presentation of otogenic dural sinus thrombosis (DST) as a complication of acute otitis media (AOM) can be masked by antibiotic treatment. Morning episodes of vomiting and/or headache, visual impairment and a history of AOM seem to be indicative of otogenic hydrocephalus. We therefore advocate that the MRI scans of patients with similar symptoms should be carefully studied to facilitate the early diagnosis of a potentially life-threatening complication. OBJECTIVE: To describe the frequency, pathognomonic signs, clinical course and outcome of otogenic hydrocephalus and DST as complications of AOM in pediatric patients. MATERIAL AND METHODS: We undertook a retrospective chart review of all pediatric patients (age 1-14 years) treated for otitis media and its complications at an academic medical center between 1999 and 2003. The main outcome measures were otologic and ophthalmologic findings and CT and MRI scans at the beginning of treatment and 3 months later. RESULTS: We report on five cases with otogenic DST following AOM. All but one of them presented initially with diplopia caused by otogenic hydrocephalus. In four cases the otologic complaints had already disappeared by the time of MRI confirmation of the diagnosis. Only one child was referred with severe otologic symptoms. Management included systemic antibiotics, short-term heparin anticoagulation and surgical decompression. In our cases, even after intensive i.v. antibiotic treatment, only surgery led to a significant improvement in the clinical condition.

Unusual fatal petrositis presenting as myofascial pain and dysfunction of the temporal muscle.

Petrositis is a rare and severe complication of acute otitis media and mastoiditis. Although the extension of the inflammatory process from the petrous apex to the adjacent Meckel cave can lead to trigeminal pain, an irritation of the trigeminal nerve roots resulting in acute or chronic hyperactivity of masticatory muscles has never been reported. We report here the unusual case of an 86-year-old man who presented with a handicapping myofascial pain and dysfunction syndrome of the right temporal muscle as a heralding manifestation of an unusual form of petrositis. The patient progressively developed a retropharyngeal abscess, a right sphenoid sinusitis, and fatal meningitis. This case demonstrated that (1) myofascial pain and dysfunction syndrome that does not respond to conventional treatments may suggest an unusual etiology and warrant further medical investigations and a detailed medical history and that (2) petrositis can manifest itself with atypical clinical symptoms and radiologic signs.

Etat confusionnel avec pneumencéphale: quel est votre diagnostic [A patient with confusion and pneumocephalus: what is your diagnosis?]

We report the case of a 58 year old male who presented with acute meningoencephalitis and pneumocephalus (intracranial air) visualized on head CT scan. Despite the lack of typical clinical signs such as retroauricular tenderness, red tympanic membrane or otorrhea, mastoiditis was suggested by head CT scan. The patient made a full recovery after mastoidectomy and six weeks of antibiotic therapy. Streptococcus pneumoniae grew from a surgical purulent mastoid tissue sample. Mastoiditis and its complications are rare in adults. A high level of clinical suspicion is needed when a patient presents with encephalitis of unclear origin.

Multisystem Langerhans' cell histiocytosis (Hand-Schüller-Christian disease) in an adult: a case report and review of the literature.

Langerhans' cell histiocytosis (LCH) is a rare and enigmatic clonal disorder that affects mainly children. It is characterized by single or multiple granulomatous mass lesions composed of cells with the Langerhans' cell phenotype. Clinical presentation and behavior are heterogeneous and can range from a solitary lytic bone lesion (i.e., eosinophilic granuloma) with a favorable course to a fatal disseminated leukaemia-like form, with a wide spectrum of intermediate clinical presentations between these two extremes. Although LCH typically involves the bone, lesions can be found in almost all organs. We are reporting the case of a multisystem LCH in a 47-year-old patient who presented with a panhypopituitarism and diabetes insipidus, and who, 5 years later, developed mandibular, mastoid and femoral lesions. The final diagnosis of LCH was made on mandibular biopsy.
