Granular cell astrocytoma (GCA) is a rare type of infiltrative brain tumor with most reported cases occurring in the suprasellar region. A pineal localization is extremely rare, with only 4 previously reported cases in the literature. The authors describe the case of a 16-year-old boy who developed signs of increased intracranial pressure and Parinaud syndrome. Cranial CT and MRI revealed a well-demarcated and enhanced mass in the pineal region accompanied by obstructive hydrocephalus. Subtotal resection was performed via a subtemporal approach. A histological diagnosis of GCA was made. Three years after surgery, the patient was alive and well without adjuvant therapy, and serial MRI showed no signs of progression of a small residual tumor. After a thorough review of the different epidemiological, clinical, and imaging features; treatments; and prognoses of GCAs in other intracranial localizations, the authors analyzed features of this tumor in the pineal region.
Le ganglioneurome est une tumeur nerveuse bénigne rare, d'origine neuroectodermique et de localisation rétropéritonéale fréquente. Nous rapportons l'observation d'un patient de 55 ans dont la tumeur est révélée fortuitement sur une échographie abdominale demandée dans le cadre d'une cytolyse hépatique secondaire à une hépatite virale C. Le patient est opéré après la réalisation d'un scanner abdominal et d'un bilan hormonal. L'examen anatomopathologique de la pièce opératoire est en faveur d'un ganglioneurome. Devant une volumineuse masse rétropéritonéale avec état général conservé, on doit envisager le diagnostic de ganglioneurome car l'exérèse chirurgicale complète permet une guérison sans récidive. Préalablement, l'ensemble des autres diagnostics différentiels doit être éliminé.
