Ganglion and haemangioma as a cause of plantar neuritis.

AL : FIG.I.-Case 2. Operative findings. An angioma lying alongside the medial plantar nerve. Pressure due to a simple tumour has to be considered as a cause of isolated peripheral neuritis particularly in the neighbourhood of tendons and joints. Prochazka (I947) published what is apparently the first report of a patient suffering from ulnar neuritis due to a ganglion. Seddon (I952) described three cases of his own and Brooks (1952) collected 13 from various centres. Nerve pressure due to ganglia has now been described at the wrist, the elbow, knee and ankle. In the foot, neuritis due to a plantar neuroma situated between the metatarsal heads is a well recognised condition described in detail by Betts (1940) but I have been able to trace only one previous reference to plantar neuritis due to ganglion (Brooks, 1952), and to angioma (Berry, I957). Case Reports Number One Mrs. P.T., agcd 38. Three months before admission, while wearing bedroom slippers at home after leaving work, she suddenly developed a cramp in her right foot. Since then she had had cramps, aching and tingling in the outer part of the sole of her foot. Her symptoms were cortinuous, and severe at night. Examination.
