Initial MR imaging patterns of transient lesions (92% of lesions) are different from those of irreversible lesions. Transient lesions suggest insufficiency stress fractures, while irreversible lesions suggest avascular osteonecrosis.

Magnetic resonance imaging appeared as a well suited neuroimaging modality in methanol intoxicated patients both in revealing a specific pattern of brain lesions and in demonstrating valuable correlation between evolution of brain changes on magnetic resonance images and clinical outcome.

Amphiphysin, a synaptic vesicle protein, is an auto-immune target in rare cases of paraneoplastic neurological disorders. We report two additional cases with distinct neurological syndromes and paraneoplastic anti-amphiphysin antibodies. The first patient, a 59-year-old man, presented with cerebellar and cranial nerve dysfunction and small cell lung carcinoma. The second, a 77-year- old woman, presented with left brachial plexopathy followed by sensorimotor neuropathy and breast carcinoma.
