Disseminated cysticercosis incidentally diagnosed in a patient of fracture shaft of femur.

Cysticercosis is caused by the larval form of Taenia solium tape worm, cysticercus cellulose. The life cycle of T. solium consists of 2 host, the definite host is a man who harbours the adult forms of the worm in the intestine, while the intermediate host is the pig, where the larval form (cysticercus cellulose) is found in the skeletal muscle. Cysticercosis develops when human beings incidentally become the intermediate host and the eggs mature within their small intestine. The route of entry of the eggs into the human intestine may occur through autoinfection or by ingestion of contaminated food or water. Further, these eggs develop into the larval form which spread throughout the intestinal wall and are disseminated by the blood stream to brain, muscles, subcutaneous tissues or any other organ. Until now, only 50 cases of disseminated forms have been reported in the literature, with the majority of the cases being from Indian subcontinent. Regarding the clinical presentations, symptoms usually depend on the location, size and number of cysts in the involved lesion. However, it may present occasionally with dementia, muscular hypertrophy or subcutaneous nodules with relative absence of focal neurological signs or raised intracranial pressure. We, here, report a case of disseminated cysticercosis, detected incidentally in a man aged 52 years who presented with an open fracture of the right femur. 2017 BMJ Publishing Group Ltd.
