The goal of surgery is complete tumor removal without morbidity. An exact analysis of tumor growth and its involvement of different structures is mandatory before performing surgery.

The treatment of subdural collections in infants remains controversial. In order to evaluate the treatment guidelines that we developed on the basis of our earlier experience, we have reviewed the results obtained in 31 consecutive infants with symptomatic chronic and subacute subdural collections treated with external drainage. Using our guidelines for removal of the drains, there was only a very low rate of permanent shunting (4/31), with a low complication rate and good clinical results. However, the long period of external drainage, and therefore of hospitalization, might make if general application of these guidelines problematic.

A patient, recently diagnosed with non-Hodgkin lymphoma, presented with acute tetraplegia after surgical cervical lymph node biopsy. MRI of the cervical spine demonstrated an epidural space-occupying lesion with compressive myelopathy. While epidural hematoma was the tentative diagnosis, intra-operatively non-Hodgkin lymphoma was found. Several factors may have accounted for the inaccurate interpretation of the MRI: the acute clinical presentation appearing shortly after surgery, the non-specific signal intensities of (hyper-) acute hematomas, the lack of contrast-enhanced images, and the absence of the FDG-avid spinal mass in the PET/CT-report. Without radiological features of invasiveness and contrast-enhanced images, careful interpretation is mandatory for space-occupying epidural lesions.Teaching Point: Caution is needed when interpreting an epidural space-occupying lesion in the absence of contrast-enhanced images.
