CT and MRI Diagnosis of Central Neurocytoma: A Report of3 Cases with Literature Review

Objective To discuss CT and MRI findings of central neurocytoma. Materials and Methods CT and MRI findings in 3 patients with pathologically-proved central neurocytoma were retrospectively analyzed and the relevant literatures were reviewed.Results In 2 cases, the lesions were located in lateral ventricle and were originated from the septum pellucidum, extending into uni- or bi-lateral ventricles. The lesion showed a mixed density (n=2) and calcification (n=1) on CT, while displayed mixed signal and marked inhomogeneous enhancement on MRI. In the remaining case, the tumor was located in left temporal lobe, presenting calcification on CT and cystic degeneration, ring-like enhancement on MRI without obvious space-occupying effect.Conclusion Central neurocytoma is a rare intracranial neoplasm. It carries certain characteristics in its occurrence age and the lesion's location, as well as in CT and MRI manifestations.
