The role of radiosurgery after multimodality treatment of recurrent desmoplastic adult medulloblastoma is analyzed. The ultra-early clinical and pathological response of this tumor to adjunctive radiosurgery is stressed.

[Usefulness of hyperbaric oxygen in the treatment of radionecrosis and symptomatic brain edema after LINAC radiosurgery]. / Eficacia del oxígeno hiperbárico en el tratamiento de la radionecrosis y el edemacerebral sintomáticos tras radiocirugía con acelerador lineal.

Radionecrosis with brain edema is a complication of radiosurgery. Three female patients harbouring a frontal pole, petrous and parasagital parietoocipital meningiomas respectively who had been treated with LINAC radiosurgery are presented. Those patients developed, between two and eight months later, a severe symptomatic radionecrosis with a huge brain edema resistant to the usual steroid therapy. Only after 40 sessions of hyperbaric oxygen, a good remission of the lesions was obtained. There are few cases reported in the literature with such a good outcome. Consequentely, this therapy must be taken into account to treat this type of radiosurgical complication before considering surgery.

[Retroperitoneal cystic lymphangioma in childhood]. / Linfangioma quístico retroperitoneal en la infancia.

UNLABELLED: Lymphangiomas are very common neoplasms in infancy. However, a retroperitoneal location is seldom observed. We present the case of a male with a history of chronic recurrent pain over a period of several years. An X-ray showed a calcic density in the left upper abdominal quadrant; the histological study revealed it to be a mixoid cystic lymphangioma. Clinical presentation varies greatly from an asymptomatic mass to serious complications. In order to correctly diagnose of these neoplasms it is essential to carry on ultra sound and CT examination although a simple abdominal X-ray may show calcifications as the one presented here. Treatment is always surgical and a complete extirpation should be performed, unless vital structures were are involved. Treatment with laser, fibrin and sclerotherapy have also been used. CONCLUSION: In spite of being benign neoplasms we believe they should be removed to confirm diagnosis and avoid possible complications.
