Answer 21

Subcutaneous nodules are a typical finding in:

True a. neurofibromatosis
False b. hydatid disease
True c. cysticercosis
True d. onchocerciasis
False e. trichinosis

In hydatid disease the cysts are typically found in the liver and the lung.

The cysts in cysticercosis may be multiple. They calcify (and therefore become radio-opaque) after 4-5 years.

Nodules in onchocerciasis are less numerous and are usually found over bony prominences. There is also abundant evidence of itching.
