Abstract
We present two cases of intracerebral recurrence of primary intrathoracic rhabdomyosarcoma, occurring within 2 months of each other. Both had embryonal histological features. One (case 1) almost certainly arose within the lung adjacent to a developmental cyst; the intrathoracic site of origin of the other (case 2) was difficult to ascertain. Both were treated on SIOP MMT protocols. The intracerebral deposits became clinically apparent soon after completing chemotherapy. They were removed surgically and second‐line chemotherapy was given both systemically and intrathecally. Neither received radiotherapy. The disease recurred in both children whilst on therapy and they died as a consequence of raised intracranial pressure.
