Hypothalamic hamartoma associated with a craniopharyngeal canal.

Respiratory Epithelial Adenomatoid Hamartoma: A Very Rare Entity Originating from the External Auditory Canal

Respiratory epithelial adenomatoid hamartoma (REAH) is an uncommon lesion of the upper aerodigestive tract. It is characterized by abnormal glandular formations with ciliated epithelium arising from the nasal cavity, paranasal sinuses and nasopharynx, but other locations have also been described. We did not find any other cases of this hamartomas in the external auditory canal in the literature...

Craniopharyngeal canal and its spectrum of pathology.

BACKGROUND AND PURPOSE The craniopharyngeal canal is a rare, well-corticated defect through the midline of the sphenoid bone from the sellar floor to the anterosuperior nasopharyngeal roof. We reviewed a series of craniopharyngeal canals to determine a system of classification that might better our understanding of this entity, highlight the range of associated pathologic conditions, and optimi...

Recurrent meningitis and persistence of craniopharyngeal canal: case report.

OBJECTS Craniopharyngeal Canal is a rare malformation of the sphenoid bone described in up to 0.42% of the asymptomatic population. It's been related to the development of the Rathke's pouch during embrionary period although some authors think it's a vestige of a former vascular channel. METHODS This report details a case of a four and a half years old child that developed recurrent meningiti...

Pathophysiology and Treatment Options in Trigeminal Meningoceles

Trigeminal meningoceles, lateral to the maxillary nerve (V2), have seldom been reported as underlying pathology for spontaneous rhinoliquorrhea. In contrast to sphenoid meningoceles arising from a persistent lateral craniopharyngeal canal (Sternberg-Cruveilhier, medial to V2), their occurrence seems to be generated by addition of erosive processes to the constitutively thin bony shell underneat...
