A 60-year old man with intracranial space occupying lesion, presented with difficulty in intubation at induction of anaesthesia. Several attempts at direct tracheal intubation were made until the airway was finally secured. Though the brain was slack, the tumour could not be located at this operation. He presented for re-operation with worse signs of raised intracranial pressure which may accompany repeated attempts at intubation, a planned translaryngeal guided intubation was employed to secure the airway. Where fibreoptic laryngoscope is unavailable and difficult tracheal intubation is envisaged, translaryngeal guided intubation may save time and reduce morbidity of prolonged and repeated attempts at tracheal intubation.
The case of an ectopic craniopharyngioma arising from a seed of tissue deposited along the operative track is reported. The uniqueness of this lesion is addressed. Ideal therapy and controversies regarding radiation therapy of craniopharyngiomas are discussed in light of this new variation in recurrence.
Two rare cases of entirely suprasellar Rathke's cleft cyst were reported. Case 1. A 62-year-old man was admitted to our hospital on the 14th of January, 1988, complaining of headache and diplopia. A plain skull x-ray showed the sella turcica was normal. CT scan and MRI demonstrated a lesion mass located entirely in the suprasellar cistern. Right frontotemporal craniotomy was performed, and the cyst wall was resected subtotally. Microscopic sections of cyst wall showed ciliated single layer with focal stratified epithelium. Case 2. A 51-year-old man was hospitalized complaining of visual impairment in the left eye. Endocrinological examination showed no abnormalities. CT and MRI demonstrated a lesion mass located entirely in the suprasellar region. Right frontotemporal craniotomy was performed. The mass was opened and a large amount of yellowish fluid was released. Histologically, the specimens were simple ciliated cuboidal epithelium. Postoperative courses of these patients were uneventful. The findings on CT and MRI of the cases located entirely in the suprasellar region were varied. The histopathogenesis and embryological pathogenesis of Rathke's cleft cyst in the literature, particularly the entirely suprasellar type, were discussed.
