Endoscopic endonasal management of congenital intranasal meningocele in a 2-month-old infant

INTRODUCTION

Nasal meningocele, which is usually congenital, is a rare anomaly resulting from meningeal herniation into the nasal cavities through a bone defect in the skull base.

CASE REPORT

An 8-day-old boy was referred with respiratory disturbance and nasal obstruction. Examination showed a cyst-like grayish swelling filling the right nasal cavity. CT scan showed opacity, of fluid-like density, filling the right nasal fossa, in contact with a small bony defect in the right cribriform plate. MRI ruled out herniated brain parenchyma and enabled diagnosis of meningocele. The patient was operated on at the age of 2 months through a transnasal endoscopic approach. Immediate postoperative course was favorable. MRI control at 8 months was normal.

DISCUSSION

Modern imaging (CT scan and MRI) is of paramount importance in the preoperative evaluation of nasal meningocele. Endoscopic endonasal (EE) surgery is currently the treatment of choice.

CONCLUSION

Steady progress in instrumentation, technique and skills will increase the feasibility of skull-base surgery using an endonasal approach in the pediatric population.

[Bronchoscopic findings in children with prolonged respiratory symptoms]

OBJECTIVE

This retrospective study aims to establish an algorithm indicating a bronchoscopy, based on clinical and radiological criteria predictive of the presence of a foreign body (FB), in children with prolonged respiratory symptoms and no history of foreign body aspiration (FBA); to establish a study of these criteria and to compare the clinical, radiological and broncoscopic findings in such cases.

METHODS

We chose to review the records of 73 children (age < or = 15 years) with prolonged respiratory symptoms (for at least 15 days) and no history of FBA who underwent bronchoscopy at our institution between 1996 and 2005.

RESULTS

The mean age was 3 years and 2 months, the majority of the patients were between 1 and 3 years of age (56%), 59% of the patients were boys and the mean of evolution of symptoms before the broncoscopy was 3 months and 3 weeks. We found a foreign body (FB) in 17 cases (23.2%). The FBs were in 88.2% of the cases of vegetable origin. A granulation tissue was associated in 47% of positive bronchoscopies. There were no complications related to bronchoscopy. The clinical and the radiological findings were no specific of FBs.

CONCLUSION

Bronchoscopy must be indicated in suspected cases of FBA to prevent delayed diagnosis and pulmonary sequelae. The clinical and radiological findings may help the clinician to indicate it.

Lymphomes T/NK du nasopharynx

OBJECTIVE

Discussion of the clinical and paraclinical features of a rare tumor in the nasopharynx, the NK/T-cell lymphoma, with an emphasis on the implications of Epstein Barr Virus (EBV) in its pathogenesis and prognosis.

CASES REPORT

We report the cases of a woman and a man aged 34 and 48, respectively. Clinical presentation was non-specific and diagnosis was established with deep biopsies under general anesthesia. Immunochemistry and in situ hybridization were positive for Epstein Barr virus in tumor cells in both cases. The patients were first treated with chemotherapy (CHOP regimen), then underwent radiotherapy. The first patient achieved complete response at twenty months follow-up. The second patient presented two recurrences which were treated by chemotherapy. He died from acute renal failure during treatment of the second recurrence.

CONCLUSION

Diagnosis of NK/T-cell lymphoma may be delayed in the event of non-specific symptoms. Deep biopsies outside necrotic tissue must be obtained. Search for EBV is important as its presence is a factor of poor prognosis.
