Figure 1. Platelet count over time. Patient presented to our institution with intracerebral and third ventricular hemorrhage at which time hematology was consulted. Looking back on prior platelet trends, patient had been hospitalized multiple times for recurrent episodes of severe thrombocytopenia. Upon pattern recognition, a diagnosis of cyclic thrombocytopenia was made and patient was initiated on cyclosporine A. Platelets stabilized to > 5.0 × 104/µL, a threshold recommended by neurosurgery in the setting of ventriculoperitoneal shunt placement, for nearly 3 months.
