A Rare Case of Reversible Splenial Lesion Syndrome with Extracallosal Lesions in the Setting of Deep Anemia
A 35-year-old female patient was admitted to our emergency department with impairment of consciousness, and somnolence. It was learned that the patient had been suffering from headache and anorexia over the last week. The clinic had begun abruptly, and the patient deteriorated over the last 5 hours before admission. The other medical history was unremarkable, and the patient had no history of recent drug use or an infection. The vital signs at admission to the emergency service were within normal limits. The neurological examination revealed that the patient was nonoriented and mildly cooperative. She could not cooperate properly with the examination and an increase in motor and psychological activity was apparent that was compatible with agitation. Other investigations including motor, sensory, and cerebellar tests were roughly within normal limits. The Kernig's and Brudzinski's signs were negative. The laboratory investigations revealed severe iron deficiency anemia (hemoglobin [Hb]: 5.3 mg/dL, serum ferritin: 30 μg/L), mild hyponatremia (131 mM/L [136–146 mM/L]), hyperkalemia (5.1 mM/L), neutrophilic leukocytosis (neutrophil: 89%), and increment of C-reactive protein (27.9 [0–0.8]). The results of the other investigations including liver-kidney functions, thyroid functions, vitamin B12, and folic acid were within normal limits. The initial cranial magnetic resonance imaging (MRI), performed on the 9th hour of the clinic, was normal ([Fig. 1]). Lumbar puncture investigations revealed normal cerebrospinal fluid (CSF) biochemistry, microscopic examination, and the result of the CSF culture was negative. The infectious disease specialist did not consider an infectious etiology of the central nervous system to explain the clinic. Routine electroencephalogram showed mild slow background activity (7 Hz) without discharge and focal slow activity. At this point, the MRI was repeated the day after, which showed restricted diffusion in the splenium, bilateral corona radiata, and left hippocampus ([Fig. 1]). Two-unit red blood cell (RBC) transfusion was administered for deep anemia (the follow-up test revealed Hb level of 8.3 mg/dL and Na level of 134 mM/L) and methylprednisolone 1 g intravenous treatment was initiated considering a possible underlying limbic encephalitis or autoimmune encephalitis.
