Tectal glioma presenting with clinical triad of obesity, amenorrhea and central cord syndrome with radiological pentad of hydrocephalus, empty sella, suprapineal diverticula, Chiari and syrinx.

BACKGROUND

Tectal gliomas (TG) are slow-growing tumors and generally present with features of increased intracranial pressure.

CASE DESCRIPTION: We describe an unusual case of a young girl who presented with clinical triad of obesity, primary amenorrhea and central cord syndrome. The radiology unveiled a pentad of hydrocephalus, empty sella, suprapineal recess diverticulum, secondary Chiari malformation and cervical syringomyelia, masking a relatively obscure tectal plate glioma. She was subjected to endoscopic third ventriculostomy (ETV). All of her symptoms improved after ETV and the tumor is being followed up. The possible pathogenesis of such a highly atypical clinico-radiological presentation is described.

CONCLUSION

This unusual syndromic presentation of tectal glioma without clinical features of increased intracranial pressure is probably due to increased compliance of third ventricular walls, and is relieved with ETV.
