case_images: Computed tomography (CT) scan of the chest. (A) As part of his evaluation after haematopoietic stem cell transplantation, chest CT was unremarkable on day + 92. (B) On day + 123, the patient developed a fever and anorexia, and chest CT revealed a new right upper lobe defined nodule (17 x 15 mm) surrounded by a ring of consolidation. Chest CT scans, which were performed on days + 152 (C), + 251 (D), and + 519 (E), respectively, demonstrated a gradual reduction of nodule size. (F) On day + 540, the chest CT revealed that the original right upper lobe nodule disappeared completely.

case_images: Computed tomography (CT) scan of the chest (Figure 1) revealed a new right upper lobe defined nodule (17 x 15 mm) surrounded by a ring of consolidation. Regular CT scans of his chest (Figure 1) revealed that the original right upper lobe nodule disappeared completely.
case_images: Brain magnetic resonance imaging (MRI) findings. T1, magnetic resonance T1-weighted imaging. T2, magnetic resonance T2-weighted imaging. On day + 138 after haematopoietic stem cell transplantation (HSCT), the patient experienced persistent headache and violent mood swings. The follow-up MRI-T1 (AT1) and MRI-T2 (AT2) identified signal abnormalities (see yellow arrows) suggestive of left-side basal ganglia abscesses (28 x 18 mm) and signs of perifocal oedema (pre-operation). On day + 141 after HSCT, intracranial debridement was performed on the child. On day + 164 after HSCT, MRI-T1 (BT1) and MRI-T2 (BT2) showed that the basal ganglia mucormycosis was completely removed post-operation. On day + 183 after HSCT, MRI-T1 (CT1) and MRI-T2 (CT2) were performed post-operation. On day + 216 after HSCT, MRI-T1 (DT1) and MRI-T2 (DT2) were performed post-operation. On day + 251 after HSCT, MRI-T1 (ET1) and MRI-T2 (ET2) were performed post-operation. On day + 339 after HSCT, MRI-T1 (FT1) and MRI-T2 (FT2) revealed that the surgical site appeared to be healing well with a gradual reduction in size.

case_images: A follow-up brain magnetic resonance imaging (MRI; Figure 2) identified signal abnormalities suggestive of left-side basal ganglia abscesses (28 x 18 mm) and signs of perifocal oedema. The preoperative and postoperative lesion volume changes were evaluated using brain MRIs (Figure 2) and demonstrated a gradual reduction.
