Background: Even today patients who suffer from mantle cell lymphoma have a poor prognosis, especially when the CNS is involved. To confirm the diagnosis of meningeosis lymphomatosa, asservation of the liquor cerebrospinalis is necessary. During this procedure, intrathecal chemotherapy may be given if there is clinical evidence of meningeosis. If lumbar puncture cannot be performed, a lateral suboccipital puncture may be an alternative approach. Patient and Methods: We report the case of a 65-year-old patient who suffered from mantle cell lymphoma stage IV. The patient presented with symptoms of progressive paraparesis of both legs and incontinence, with tumor mass intradural from the 12th thoracic vertebra to the level of S1. During irradiation, the patient developed symptoms of diffuse meningiosis lymphomatosa. The conventional lumbar puncture was impossible, because of tumor present in the thoracico-lumbar junction. Results: A suboccipital puncture was performed for both collecting cerebrospinal fluid and application of chemotherapy ( cytosine arabinoside/dexamethasone). This lead to remarkable improvement of the patient's clinical symptoms. Conclusion: The suboccipital cervical puncture was performed without complications. A variation of the intrathecal approach is described, which may serve as alternative when conventional lumbar puncture is not possible.
