Central neurocytoma with craniospinal dissemination.
We report a case of central neurocytoma that manifested tumor recurrence with craniospinal dissemination. Imaging studies before surgery showed a markedly enhanced tumor with small cysts and calcification, which invaded the adjacent brain parenchyma, located in the posterior horn of the right lateral ventricle. Proton MR spectroscopy showed markedly elevated choline and lactate peaks with a str...
متن کاملSeeding of a Pituitary Adenoma or Atypical Pituitary Carcinoma?
Pituitary carcinomas are defined as pituitary tumors with craniospinal and/or systemic metastasis. These are rare and highly aggressive lesions. We present an unusual case of a 52-year-old male who had a pituitary adenoma removed via craniotomy. The tumor recurred three years post-op near the surgical tract, and slowly enlarged before removal two years later. Technically, this lesion was define...
متن کاملCase Report: Co-Occurrence of Pituitary Adenoma with Suprasellar and Olfactory Groove Meningiomas
Introduction: The co-existence of pituitary adenoma and meningioma is extremely rare. It is even rarer in patients with no previous known risk factors for either tumour. Here, we present a case of synchronous non-functioning pituitary adenoma with suprasellar and olfactory groove meningiomas in a patient without previous irradiation. Methods: The tumours were diagnosed on MRI in the 65-year-ol...
متن کاملAn atypical pituitary adenoma with a high degree of malignancy: a case report
Background: Pituitary carcinoma is very rare and hard to diagnose. However, some atypical pituitary adenomas present with a high rate of proliferation and extensive invasion, suggesting a tumor with a high degree of malignancy. Case presentation: Here, we present a case study of this type of tumor. A 46 years old women was admitted for headaches and impaired vision, and MRI and CT revealed a se...
متن کاملPeritoneal dissemination from central neurocytoma: case report.
OBJECTIVE Central neurocytoma is a low grade tumor of neuroglial origin and a relatively new histological entity. Only a few cases have been reported and its biological behavior is still uncertain. Some cases have shown an aggressive behavior (local recurrence, malignant dedifferentiation or CSF dissemination) and challenged the initial view of its relative benignity. A case of central neurocyt...
