Relapsed neuroblastoma treated with 4 cycles chemotherapy. Orbits: The lobulated heterogeneous mass arising from the left lateral orbital wall has not significantly changed in size, measuring up to approximately 3.0 cm, previously also approximately 3.0 cm, with slide left lateral extraconal space and bulging into the left masticator space via subperiosteal extension, but no significant mass effect upon the intraorbital contents. The right orbit is unremarkable.Brain: There are postoperative findings related to left pterional craniotomy. There is persistent diffuse enhancement within the left foramen rotundum. There is no discernible tumor within the cavernous sinuses or Meckel caves. Aside from the minimal epidural extension of tumor associated with the left lateral orbital wall tumor, no other intracranial tumors are apparent. There is no evidence of intracranial hemorrhage or acute infarct. There is mild mega cisterna magna. Otherwise, the ventricles and basal cisterns are normal in size and configuration. There is no midline shift. There is diffuse paranasal sinus mucosal thickening and secretions. There is fluid and mucosal enhancement within the bilateral middle ears and mastoid air cells.
1. No significant interval change in size of tumor arising from the left lateral wall of the orbit.2. Persistent diffuse enhancement within the left foramen rotundum, which may represent the residual of treated perineural tumor.3. Diffuse paranasal sinus mucosal thickening and secretions.4. Persistent fluid within the bilateral middle ears and mastoid air cells.
