Superior Rectus Muscle

We present the unusual case of a 74 year-old female with a history of breast cancer who presented with acute painless orbital swelling and vertical diplopia. MRI revealed a focal enhancing mass within the superior rectus muscle. As the concern for metastatic disease was high, surgical biopsy was performed and revealed an unusual mimicker of metastatic disease, the parasitic infection dirofilariasis.

Superior Rectus Muscle

Human cysticercosis is caused by the larval form of the swine tapeworm Taenia solium.It can affect the central nervous system, the eye, skeletal muscles and subcutaneous tissues. In the orbit, cysticercosis can lodge into any extraocular muscle or other adnexal structures and are usually found as part of a generalized systemic infestation and very rarely seen with isolated infestation of a single extraocular muscle.Hence, sometimes as it was in our case,it is very difficult to differentiate an isolated extraocular muscle cysticercosis from extraocular muscle abscess or lymphoma. So,we, at our institute report a rare and unusual case of isolated right superior rectus muscle cysticercosis which presented with ptosis and painless swelling of the right upper eyelid, which was in fact discovered later masquerading as a superior rectus abscess.

Orbital Region

Cat extraocular muscles consist of two regions: orbital, and global. The orbital region contains predominantly small diameter fibers, while the global region contains a variety of fibers of different diameters. The differences in ultrastructural features among these muscle fibers indicate that the extraocular muscles of cats contain at least five structurally distinguishable types of fibers.Superior rectus muscles were studied by light and electron microscopy, mapping the distribution of each fiber type with its distinctive features. A mixture of 4% paraformaldehyde and 4% glutaraldehyde was perfused through the carotid arteries of anesthetized adult cats and applied locally to exposed superior rectus muscles during the perfusion.
