We present the case of a 40-year-old male with recent history of moderately differentiated invasive adenocarcinoma of the sigmoid in whom both respiratory and neurological disease developed simultaneously, mimicking diffuse metastatic disease. The broad differential diagnosis and pitfalls (both diagnostic and therapeutic) are described. Pulmonary sarcoidosis as well as neurosarcoidosis occur very rarely after solid cancers.
Keywords: chemotherapy; differential diagnosis; meningoencephalitis; neurosarcoidosis; sigmoid cancer; transverse myeli-tis.
