-
A 4-year-old boy presented with sudden proptosis of his left eye.
-
Same patient as in the image above. A CBC revealed anemia (Hb 8.6 mg/dL), thrombocytopenia (64,000), and leukocytosis (12,900). The peripheral smear revealed the presence of blasts 28%, lymphocytes 44%, segmented 14%, monocytes 6%, bands 2%, metamyelocytes 1%, and myelocytes 1%. The boy was diagnosed with AML type M4-M5 chloroma of the left orbit.
-
CT scan reveals infiltration in the left orbit. Notice that the bone is uninvolved. A lumbar puncture revealed that the cerebral spinal fluid was clean of leukemic cells.
-
Systemic chemotherapy was instituted, and the proptosis resolved. Unfortunately, 4.5 months later, the boy passed away secondary to multiorgan failure.
-
An impending bilateral central retinal vein obstruction was discovered during a routine examination of a 76-year-old man. Further workup revealed a WBC count of 709,000, a hemoglobin count of 12 mg/dL, and a platelet count of 104,000. The man was eventually diagnosed with CML. This image is a red-free photograph of the right fundus. Notice the intraretinal hemorrhages.

A 14-year-old boy with a past medical history of ALL complained of a sudden loss of vision OD. Visual acuities were counting fingers OD and 20/20 OS. Notice the macular hemorrhage responsible for the loss of vision. Courtesy of Dr Rafael Jiménez.

Same patient as in the previous image. The hematological workup revealed a hemoglobin count of 5.6, a WBC count of 1800, and a platelet count of 3000. Courtesy of Dr Rafael Jiménez.
