Presentation
Incidental finding during work-up for TIA/ intracranial event. The patient presents with dysarthria and right hemiparesis.
Patient Data
There is linear, somewhat symmetric, calcification within the 4th ventricle extending through the foramina of Lushka.
Incidental findings:
bilateral vertebral arterial calcified plaque
extensive artefact emanating from the dental implants
posterior fossa involution appropriate for age
punctate dermal calcifications
prominent external occipital protuberence
Case Discussion
Bochdalek's flower basket is a term given to the appearance of linear choroid plexus calcification within the 4th ventricle that protrudes through the paired foramina of Lushka.
This may mimic a possible subarachnoid haemorrhage especially when linear in appearance or a cerebellopontine angle mass lesion especially when dense or bulbous in appearance.
Contrast enhancement of bulbous protruding choroid plexus may cause confusion in image interpretation during routine CT and MRI brain studies1.
