A rare case of diminished visual acuity: neurohypophyseal granular cell tumor

A neurohypophyseal granular cell tumor was found in a 60-year-old man who presented diminished visual acuity. Neuronavigation resection via a fronto-pteronial approach removed split up material. The diagnosis was established by histology and immunochemical studies. Granulous cell tumors, which are c...

More Information
Summary:A neurohypophyseal granular cell tumor was found in a 60-year-old man who presented diminished visual acuity. Neuronavigation resection via a fronto-pteronial approach removed split up material. The diagnosis was established by histology and immunochemical studies. Granulous cell tumors, which are common, are rarely located in the neurohypophysis. Their origin remains a subject of debate, but unlike the other localizations, these tumors in the sellar and/or supra-sellar area are always considered benign. The clinical course depends on the quality of the surgical resection; there is no consensus on appropriate management.
