OBJECTIVE: It is classically considered that the morbidity and mortality rates are greater for
stereotactic biopsies of pineal region tumors, compared with tumors in other regions …

Most pineal region masses are malignant germ cell neoplasms that occur in young male
patients. The most common is a germinoma, which is a homogeneous mass with signal …

Our aim was to review the MRI appearances of primary intracranial germ-cell tumours
(GCT). We reviewed the MRI studies of 32 patients: 19 with germinomas, five with teratomas …

The authors advocate an aggressive surgical approach to pineal region tumors to provide a
definitive histological diagnosis and to facilitate extensive tumor removal. This strategy is …

Lesions of the pineal region include a diverse group of entities. The most common
neoplastic lesions are the germ cell tumors. Germ cell tumors may be hormonally active, and …

• The germinoma represents a less malignant form of germ cell tumor. Depending on the
individual's age, this neoplasm constitutes approximately 0.1% to 3.4% of all intracranial …

MR brain scans of 672 consecutive patients were examined prospectively to determine the
incidence of high-signal pineal glands on T2-weighted images. The scans were obtained on …

The computed tomographic (CT) and magnetic resonance imaging (MRI) features of 73
histologically proven primary intracranial germ cell tumors were analysed. CT images were …

MR images of pineal region tumors were analyzed in 26 patients with histologically proved
tumors: seven germ-cell tumors, six astrocytomas, five teratomas, three pineoblastomas, two …

✓ To optimize orientation and operative exposure for aggressive resection, the authors
approached pineal region tumors transtentorially with the patient in a semisitting position. In …
