A tale of two sit-bones: The cyclist's ischial hygroma (Perineal nodular induration).

The ischial hygroma, also known as a perineal nodular induration, is a relatively rare and mostly cycling-specific injury that is often incorrectly diagnosed and managed. Here two cases with divergent managements are described to highlight the spectrum of treatment available to manage this condition. The presentation, assessment and management of two cases of perineal nodular induration are discussed. The management options, namely surgical excision vs conservative management, with saddle pressure mapping highlight that there is no single optimal method and that a multidisciplinary approach should be applied to treat these injuries successfully. Perineal nodular induration should be investigated appropriately to exclude less benign causes of perineal masses. Conservative management and surgical excision can both be successful. Clinicians should be familiar with the assessment and management of this relatively rare but debilitating condition in competitive cyclists.

Splenic rupture caused by a cricket ball. A case report.

A 14-year-old boy presented with a ruptured spleen after being injured by a cricket ball during a match. A typical picture of splenic rupture with intra-abdominal haemorrhage was evident on admission to hospital. At emergency laparotomy splenorrhaphy was not feasible because of a deep hilar laceration and splenectomy was performed.

Traumatic superior mesenteric arteriovenous fistula. A case report.

In a case of traumatic superior mesenteric arteriovenous fistula resulting from a stab wound in the abdomen clinical signs of high-output cardiac failure or portal hypertension were absent. Selective angiography was useful in confirming and locating the fistula. The patient made a good recovery after resection of the aneurysm and fistula and insertion of a prosthetic graft.
