[en] Disorders of the choroid plexus, a central nervous system structure, are rare, but can pose diagnostic difficulties. The purpose of this review is to illustrate the computed tomography and magnetic resonance imaging findings of a wide spectrum of lesions that affect the choroid plexus. The areas covered include (1) neoplasms (papilloma, leukaemia, meningioma, lymphoma and metastases); (2) infections (bacterial, fungal and viral); (3) cysts; (4) haemorrhage; (5) congenital abnormalities (Sturge-Weber syndrome, Klippel-Trenaunay-Weber syndrome and vascular malformations); and (6) non-infectious inflammatory disorders (xanthogranulomas, inflammatory pseudotumour, neurosarcoidosis, rheumatoid nodule and villous hypertrophy). Few of the patterns of choroid plexus involvement are specific for a particular pathological process. Guermazi, A. (2000)

[en] Fanconi's anaemia is a severe refractory anaemia, associated with congenital malformations in approximately two-thirds of cases. Although these malformations may involve every organ system, suggestive dysmorphic features include growth retardation, radial ray deformities and urinary malformations. These malformations are not specific for Fanconi's anaemia, but should be recognized during pregnancy, or later in childhood, and suggest the possibility of inherited haematopoiesis disorders.
