| Lafora body disease | A form of progressive myoclonus epilepsy beginning from age 6 to 19; characterised by generalised tonic-clonic seizures, resting and action myoclonus, ataxia, dementia, and classic EEG findings, including polyspike and wave discharges; basophilic cytoplasmic inclusion bodies present in portions of the brain, the liver, and skin, as well as the duct cells of the sweat glands. Death usually occurs within 10 years of onset; autosomal recessive inheritance. Synonym: Lafora's disease. (05 Mar 2000) |

| foreign body aspiration | <radiology> 80% most likely to be obstructive emphysema (air trapping), 20% most likely to be obstructive atelectasis, <1% most likely to be normal aeration, normal bronchi dilate during inspiration, the aspirated particle acts as a one-way valve, decubitus or inspiratory/expiratory views (12 Dec 1998) |
| foreign body giant cell | <pathology> Syncytium formed by the fusion of macrophages in response to an indigestible particle too large to be phagocytosed for example talc, silica or asbestos fibres). There may be as many as 100 nuclei randomly distributed: similar cells but with the nuclei more peripherally located (Langhans cells) are found at the centre of tuberculous lesions. (06 Mar 1998) |

| lateral geniculate body | The lateral one of a pair of small oval masses that protrude slightly from the posteroinferior aspects of the thalamus; its main (dorsal) subdivision serves as a processing station in the major pathway from the retina to the cerebral cortex, receiving fibres from the optic tract and giving rise to the geniculocalcarine radiation to the visual cortex in the occipital lobe. Synonym: corpus geniculatum laterale, corpus geniculatum externum. (05 Mar 2000) |
