Bosch-Barrera J, Urdiroz J, Centeno C. Alucinaciones visuales y dolor inusual en relación a hipomagnesemia en un paciente con cáncer avanzado. An Sist Sanit Navar 2010 Sep-Dec;33(3):319-322.
Hypomagnesemia has been related to high accumulated
doses of cisplatin, and its clinical presence is
characterized by neuromuscular and cardiovascular
We present the case of an advanced cancer patient
who had received successive lines of chemotherapy
and who was receiving opioid treatment for cancer
pain. During his hospital stay, he experienced visual
hallucinations and very intense, unexplained pain in
one shoulder. Symptoms reverted with the normalization
of his plasma magnesium levels, which were low.
We consider that plasma magnesium levels should be
monitored in oncology patients with neurological or
psychiatric symptoms or with unusual pain.
