(A) Preoperative CT showing a crescent-shaped slightly dense shadow under the right cranial plate, with displaced midline structures and lateral ventricular compression. (B) Postoperative brain CT reexamination showing complete hematoma clearance without secondary bleeding.

CT scans showed that there was a slightly higher density of crescent-shaped shadows at the right frontal-temporal-parietal lobe, the adjacent brain ventricle was compressed, and the midline structure was displaced by 15 mm (Figure 1A). Postoperative CT scans suggested complete clearance of the right frontal-temporal-parietal subdural hematoma (Figure 1B).
Bone marrow smear cytology showed that the proportion of monocytes increased, with promonocytes accounting for ~8.2% of these cells. The cells were variable in size and irregular, mostly with processes and varied amounts of cytoplasm. Morphological analysis of peripheral blood cells showed that the proportion of classified monocytes increased, and promonocytes were easily observed.

Bone marrow aspiration and smear cytology (Figure 2), flow cytology (Figure 3), and karyotype analysis of bone marrow cells (Figure 4) were performed, leading to a diagnosis of acute myeloblastic leukemia.
Flow cytometric analysis showed that CD34+ cells accounted for 20.16% of all nucleated cells. The immunophenotypes of these cells were CD34+, CD117+, HLA-DR+, partial 4+, partial CD11b+, and partial CD13+.

Bone marrow aspiration and smear cytology (Figure 2), flow cytology (Figure 3), and karyotype analysis of bone marrow cells (Figure 4) were performed, leading to a diagnosis of acute myeloblastic leukemia.
Karyotype analysis: 45, X, Y [20]. All the cells analyzed had Y chromosome loss.
