The head and neck computed tomography (CT) radiological findings. The head and neck coronal CT in the bone window setting revealed a defect in the cribriform plate (arrow), consistent with a cerebrospinal fluid leak.

CSF test showed no evidence of meningitis and had a clear appearance (microscopy: white blood cell, 0/mm3; red blood cell, 0/mm3; protein, 0.18 g/L; CSF glucose, 5.4 mmol/L). Computed tomography (CT) scans showed a defect in the cribriform plate (Figure 1).
Preoperative chest computed tomography (CT) radiological findings. A chest axial CT in the lung window setting showed a consolidation and ground-glass opacity in the posterior segments of the right upper lobes (a) and the superior segments of the bilateral lower lobes (b), consistent with aspiration pneumonia.

Interestingly, chest CT showed a consolidation and ground-glass opacity in posterior segments of the right upper lobes and superior segments of the bilateral lower lobes (Figure 2), indicating aspiration pneumonia.
Intraoperative findings. (a) The bone defect and cerebrospinal fluid leaks were found in the right frontal ethmoidal skull base. (b) A piece of fascia was introduced through the dural defect into the intracranial cavity. The graft was gently pulled with forceps to plug the fistulae. (c) Another piece of fascia was placed as an overlay graft as the second layer. (d) A septal mucosal flap was placed as the third layer.

The bone defect and CSF leakage were found in the right frontal ethmoidal skull base (Figure 3(a)). Then, the graft was gently pulled with forceps to plug the fistulae (Figure 3(b)). Another piece of fascia was placed as the overlay graft as the second layer (Figure 3(c)). Finally, the septal mucosal flap was placed as the third layer (Figure 3(d)).
Postoperative chest computed tomography (CT) radiological findings. A chest CT in the lung window setting showed no consolidation or ground-glass opacity.
