I have the same lump on my ankle. It is similar to your description. It doesn't appear too much when the ankle is bent, but when flexed, it shows quite well. It is generally hard, but a little softer that bone. It doesn't hurt, but it is a concern. My neighbor, who works in medical records, believes it may be a Bakers cyst, but that seems to occur only in knee joints and is usually large -- like the size of a golf ball. When you find out what you have, please send me an e-mail or update this thread. I will continue to do more research and hopefully we can figure this out.
Thanks.
Hello - thanks for asking your question.
Without seeing the lesion, it is impossible for me to say what it is.
Lipomas, fibromas, neuromas, dorsal exostoses, periarticular calcaneus deposits, giant cell tumors, and synovial cysts are benign lesions that can occur as solitary or multiple lesions. Sarcomas are rare, but metastatic lesions to the digits can occur.
An MRI can determine whether this is a ganglion cyst versus any other disease. This is a very accurate test with studies suggesting a positive predictive value approaching 100 percent for diagnosis of a ganglion cyst.
If the MRI shows anything else, the next step would be a biopsy of the lesion to give a definitive answer.
Followup with your personal physician is essential.

Tumors can occur anywhere, but anything that's fluid-filled is pretty unlikely to be a tumor. MRI can help to show what it is. No test is perfect, however.
