ResumenLa presencia de lesiones quísticas de etiología oncológica en el encéfalo es cada vez más frecuente. El rol del especialista en imágenes es describir sus características, morfología y comportamiento con el contraste endovenoso, para llegar a realizar un diagnóstico presuntivo y enumerar sus diagnósticos diferenciales, y así orientar al médico tratante. Haremos una revisión de las lesiones quísticas de etiología oncológica de presentación frecuente en el encéfalo mediante tomografía computada o imágenes de resonancia magnética.

“…This tumor is frequently located in the ventricular system, filling the lateral ventricle from the foramen of Monro. At CT, the tumor presents in the form of either a polylobulated or round-shaped lesion that may be spontaneously hyperdense, isodense or mixed ( 3 , 7 ) . They are seen attached to the septum pellucidum, and may extend to both lateral ventricles ( 1 , 8 ) .…”

The present essay is illustrated with magnetic resonance images obtained at the authors' institution over the past 15 years and discusses the main imaging findings of intraventricular tumor-like lesions (ependymoma, pilocytic astrocytoma, central neurocytoma, ganglioglioma, choroid plexus papilloma, primitive neuroectodermal tumors, meningioma, epidermoid tumor). Such lesions represent a subgroup of intracranial lesions with unique characteristics and some image patterns that may facilitate the differential diagnosis.

BACKGROUND The majority of central neurocytomas are benign. Approximately 25% of these rare central nervous system tumors are more aggressive, with an MIB‐1 labeling index > 2% or atypical histologic features, and are classified as atypical neurocytomas. The objective of this analysis was to define the optimal treatment for patients with these atypical tumors. METHODS The first atypical neurocytoma was described in 1989. The patients reported since then were reviewed for age, gender, extent of resection, MIB‐1 index, histology, irradiation, local control, and survival. In addition to the data available in the literature, more relevant data were obtained from the authors of that literature. Treatment approaches included complete resection alone (CR), complete resection followed by radiotherapy (CR‐RT), incomplete resection alone (IR), and incomplete resection followed by radiotherapy (IR‐RT). These four therapies were compared for local control and survival using Kaplan–Meier analysis and the log‐rank test. RESULTS Complete data were available on 85 patients (15 patients who underwent CR, 13 patients who underwent CR‐RT, 17 patients who underwent IR, and 40 patients who received IR‐RT). Local control rates at 3 years and 5 years were 73% and 57% after CR, 81% and 53% after CR‐RT, 21% and 7% after IR, and 85% and 70% after IR‐RT, respectively (P < 0.0001). Survival rates at 3 years and 5 years and were 93% and 93% after CR, 90% and 90% after CR‐RT, 65% and 43% after IR, and 87% and 78% after IR‐RT, respectively (P = 0.0076). CONCLUSIONS Patients who underwent CR achieved better local control and survival rates compared with patients who underwent IR. After IR, patients appeared to benefit from RT. A beneficial effect of RT after CR was not observed. Cancer 2004;100:814–7. © 2004 American Cancer Society.
