| Abstract |
|
Mycoplasma pneumoniae infection is manifestated as pneumonia and extra-pulmonary symptoms
such as hematologic, neurologic, gastrointestinal, musculoskeletal, dermatologic and cardiac manifes-
tations. Among the hematologic changes, hemolytic anemia is most frequently seen. Throm-
bocytopenic purpura, lymphocytosis or rarely lymphopenia, elevated erythrocyte sedimentation rate,
positive direct Coombs test, reticulocytosis and DIC are known hematologic features.
This 12 years old female patient was presented with pneumonia and pancytopenia. Bone marrow
biopsy showed less than 10% cellularity which was compatible with aplastic anemia. Chest X-ray
finding revealed patchy hazy density in superior and lateral segments of the left lower lobe with
collapse. On the fourth hospital day, cold agglutinin titer was 1:1,024 and anti-mycoplasma antibody
titer was 1:5,120. On the thirteenth hospital day, with improvement of pneumonia, those titers
became 1: 512 and 1:5,120 respectively. Gradually reticulocyte count increased and the features of
hemolytic anemia became more prominent with improvement of chest X-ray and symtoms after
treatment with antibiotics. We concluded that she sufferred with mycoplasmal pneumonia and the
initial pancytopenia was the ‘aplastic crisis’ of hemolytic anemia which was caused by Mycoplasma
pneumoniae infection (pneumonia). |
