Cerebellar

abscess secondary to occipital dermoid cyst with dermal sinus. Sagittal View MRI Brain, T2, FLAIR images showing perilesional oedema in cerebellum and communication.

Cerebellar

abscess secondary to occipital dermoid cyst with dermal sinus. Pre contrast T1W image shows multiple foci in posterior and midline region of cerebellar folia in keeping with leakage of fat content from high signal dermoid cyst in occipital region of scalp through sinus.

Cerebellar

abscess secondary to occipital dermoid cyst with dermal sinus. Pre-contrast T1W coronal images – high signal in subarachnoid space in posterior fossa consistent with leakage of fatty content of dermoid.

Cerebellar

abscess secondary to occipital dermoid cyst with dermal sinus. MRI Brain, axial view, diffusion weighted image showed restricted diffusion.

Cerebellar

abscess secondary to occipital dermoid cyst with dermal sinus. Axial T2W image, lesion in midline with perilesional oedema and mass effect. Communication/dermal sinus tract through occipital bone defect to scalp dermoid with secondary infection. Incidental detected right sided acoustic schwannoma.

Cerebral

venous thrombosis, subdural empyema and cerebral abscess as complications of coalescent otomastoiditis. Axial CT shows small hypodense area in the right temporal lobe, which should prompt the suspicion of cerebral abscess in the given context.

Cerebral

venous thrombosis, subdural empyema and cerebral abscess as complications of coalescent otomastoiditis. MRI T2 shows small delineated hyperintense lesion with surrounding diffuse peripheral hyperintensity in the right temporal lobe, compatible with cerebral abscess with surrounding oedema.

venous thrombosis, subdural empyema and cerebral abscess as complications of coalescent otomastoiditis. B1000 and ADC images with small area of restricted diffusion in right temporal lobe.

Cerebral

venous thrombosis, subdural empyema and cerebral abscess as complications of coalescent otomastoiditis. MRI 3D reconstruction shows small peripherally enhancing area in the right temporal lobe, compatible with cerebral abscess.

Cerebellar

abscess secondary to occipital dermoid cyst with dermal sinus. Post-contrast T1W MR shows high signal foci which were non-enhancing suggesting leakage of fat containing dermoid cyst in cerebellar folia.

with pus draining from the right ear. Axial CT with contrast of the brain with bone windows (left) shows opacification and destruction of the right mastoid air cells while axial CT with contrast of the brain with soft tissue windows (right) shows a large low density ring enhancing lesion in the right cerebral hemisphere that is causing midline shift to the left.The diagnosis was right coalescent mastoiditis with an intracranial abscess.
