Radioiodinated metaiodobenzylguanidine [(131)I-MIBG] is commonly used to treat resistant neuroblastoma or metastatic pheochromocytoma [MP] with little non-hematopoietic toxicity. We describe here transient sialoadenitis, a previously unreported complication. Ten patients [9 neuroblastoma and 1 MP] received 12-18 mCi/kg of (131)I-MIBG. Five patients had bilateral parotid swelling, two with associated buccal discomfort within 24 hr of injection which subsided within 48 hr. Grade 3 or 4 serum amylase elevation was documented in 8/8 patients tested [median 1,336; range: 576-8,830 U/L] which normalized [25-125 U/L] within 4-14 [median 5.5] days. Serum lipase remained normal. Patients did not develop subsequent dry mouth or dysphagia.

The incidence, mode of presentation and management of Dancing Eye Syndrome/Opsoclonus-Myoclonus Syndrome (DES/OMS) was prospectively evaluated in 20 United Kingdom (UK) paediatric neurology centres by questionnaire over a 24-month period between 2003 and 2005. Nineteen children were notified, giving an incidence of 0.18 cases per million total population per year. Mean age at presentation was 18 months (range 3-42 months). Fifteen families consented to participate in the study. Atypical features were present in 6/15 cases including very delayed presentation of opsoclonus, dysphagia, and rapid spontaneous improvement without treatment. Only 4/15 cases were associated with neuroblastoma (NB) but current practice in excluding this is diverse and a standardised approach is suggested.

Presence of thymus in the normal position as well as in the posterior mediastinum is an unusual phenomenon. We report here a case of posterior mediastinal mass in a 20-month old male child who presented with dysphagia and dry cough. Investigations revealed it to be a solid posterior mediastinal mass, suspected to be either lymphoma or a neuroblastoma. Excision of the mass followed by histopathologic examination revealed the mass to be a normal thymus. This case indicates that a benign mass, an accessory thymus, though rare, can be located in the posterior mediastinum and cause symptoms similar to solid mediastinal tumors.

We present a case of pediatric primary cervical neuroblastoma (NB), which is extremely rare. A 3-year-old girl with ataxia but no nasal obstruction, dysphagia, or stridor was diagnosed with cervical NB. Diagnostic results including clinical chemistry, full blood count, and serology, were normal. Ataxia worsened within a few days after onset and was not cured by steroids or intravenous immunoglobulin, delaying a definite diagnosis until a tumor was detected. Opsoclonus-myoclonus syndrome is typified by opsoclonus with myoclonus and ataxia, primarily associated with neuroblastoma. Brain stem cell and cerebellum dysfunction is thought to be due to an autoimmune mechanism. Following chemotherapy and selective neck dissection, the girl has had no recurrence or adverse sequelae. Ataxia disappeared during chemotherapy. We suggest that neuroblastoma should be considered in any child with unexpected by prolonged ataxia.
