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.

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.
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.

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.
