Abstract

A 30-year-old man was admitted to Intensive Therapy Unit (ITU) with status epilepticus secondary to severe hypoglycaemia on a background of type 1 diabetes. CT of the brain showed generalised cerebral oedema. He was successfully stepped down to a medical ward after 2 weeks. He was noted to have persistently high calcium, which required multiple doses of pamidronate. Parathyroid hormone level was appropriately low. CT of the thorax, abdomen and pelvis showed mild hepatosplenomegaly with small pathological lymph nodes throughout the abdomen. Bone marrow biopsy was unremarkable. Lymph node biopsy was difficult to achieve, and therefore a positron emission tomography scan was arranged. This showed an enlarged and hypermetabolic spleen. Differential diagnoses at this point included lymphoma and sarcoidosis. He underwent diagnostic splenectomy, and the diagnosis of sarcoidosis was confirmed histologically. Calcium level remained normal 17 months after splenectomy.
