Reversible myelofibrosis due to severe Vitamin D deficiency rickets.

Neurofibromatosis is a neurocutaneous, tumor predisposing, inheritable disorder characterized by tumors of the brain and spine and the presence of skin lesions. The most important tumors associated with neurofibromatosis are vestibular nerve schwannomas, with others being meningiomas and ependymomas. The cord is also affected by tumors, ependymoma being the commonest, besides meningiomas and schwannomas. We present a case with café au lait macules, neurofibromas in the skin, bilateral VIII cranial nerve schwannomas, multiple meningiomas in the brain and spine, ependymomas in the brain and spine, and schwannomas in the cauda equina nerve roots.
