Consider the following medical report that includes the patient's historical health records. Use it to predict the disease that the patient is high likely exposed to. 

 Medical Report: history of present illness: this 69 year-old gentleman with non-hodgkin's lymphoma status post a bone marrow transplant with refractory thrombocytopenia is admitted with weakness and confusion. he was recently discharged from the hospital with severe thrombocytopenia awaiting potential splenectomy. he was found to have left hand weakness and noticed that he could not move his wrist and he was becoming more confused. he was brought to the emergency room for evaluation. past medical history: non-hodgkin's lymphoma treated with a bone marrow transplant in with recurrence status post chemotherapy. he also has chronic obstructive pulmonary disease, gastroesophageal reflux disease, clot in the inferior vena cava, glaucoma, chronic low platelets with past history of itp and also of myelofibrosis. medications: 1. calcium. 2. tylenol. 3. amicar. 4. accolate. 5. percocet. 6. danazol. 7. prednisone. 8. prevacid. 9. serevent. 10. atrovent. allergies: bactrim. physical examination: he was awake, but drowsy and arousable. temperature is 100.4. the chest was clear. there was gingival bleeding in the mouth. the abdomen was benign. on mental status he was oriented to self and to place. he was poorly cooperative. there was decreased strength in his left upper extremity. admission laboratory: hematocrit of 25.2, platelet count 51,000 after transfusion, which originally was 5000. electrolytes were normal. glucose 105. chest x-ray showed no infiltrates. hospital course: the patient is admitted with decreased mental status and thought perhaps to have intracerebral bleed. mri showed some enhancement over the right side of the brain. there was a question of carcinomatosis versus bleed. however, reread showed a probably small subarachnoid bleed. the patient was treated conservatively and attempts were made to keep his platelets in a reasonable range. he was admitted to the intensive care unit. he was followed by the stroke service and neurosurgery. over some length of time he began to improve from a neurological point of view. he remained febrile. he was placed on antibiotics. a lumbar puncture was performed and there was a question of meningitis for which he was treated with acyclovir, vanco, clindamycin and ceftriaxone. there was no evidence of lymphoma on cerebral spinal fluid cytology. over some time he continued to improve. however, his platelet count still became a significant problem. kept requiring large amounts of platelet products and had a gastrointestinal hemorrhage. consultation was then obtained again with the surgical service about the long term goals. a very long conversation was again had with the patient and his family about options and it was thought that perhaps the only way for the patient to have a reasonable life was to have a splenectomy, which may decrease the patient's requirement for platelet transfusion. it was known that this was a high risk procedure. therefore on the patient underwent a splenectomy, which was uncomplicated. the spleen was somewhat large. operation was uncomplicated. postoperatively, the patient initially did reasonably well requiring continued platelet transfusions though at a much lesser rate. however, over his intensive care unit stay he had more difficulty with respiration and required reintubation for a pneumonia. he also then had a higher requirements for platelets and red cells. there is no evidence of active bleeding, but the patient continued to have severe consumption of his platelets and probably no platelet production. he was continued to be followed by the hematology/oncology service as well. he then had severe deterioration of his respiratory function with developing ards, increasing respiratory acidosis and dead space. because of his extremely poor prognosis and the fact that the splenectomy did not improve his platelet problem as well as severe respiratory failure it was thought that further measures were to attempt to improve the situation were futile. discussion was had with the family, dr. and dr. in attendance. the decision was made to withdraw care, which was done and the patient expired. final diagnoses: 1. severe thrombocytopenia. 2. itp. 3. non-hodgkin's lymphoma status post chemotherapy and bone marrow transplant. 4. chronic obstructive pulmonary disease. 5. ventilator associated pneumonia with respiratory failure. 6. intracerebral bleed. 7. possible meningitis. no autopsy was performed. , m.d. dictated by: medquist36 procedure: venous catheterization, not elsewhere classified continuous invasive mechanical ventilation for 96 consecutive hours or more spinal tap incision of lung insertion of endotracheal tube biopsy of bone marrow arterial catheterization total splenectomy diagnoses: pneumonia, organism unspecified subarachnoid hemorrhage candidiasis of mouth bone marrow replaced by transplant acute respiratory failure infection and inflammatory reaction due to other vascular device, implant, and graft chronic obstructive asthma, unspecified reticulosarcoma, unspecified site, extranodal and solid organ sites
