RESUMEN
Exercise rhabdomyolysis is a potentially life-threatening medical condition if not adequately managed early. With the increase in the popularity of indoor cycling, known as Spinning®, over recent years, there has been an increased occurrence of spin-related rhabdomyolysis observed among previously fit adults after undertaking their first spin bike class session. They present with the triad of myalgia, muscle weakness, and dark tea-colored urine within a week of their first spin session. This case series highlights several admissions to the hospital with spin-related rhabdomyolysis and their clinical management.
RESUMEN
Schwannomas are nerve sheath tumors that occur in Schwann cells. They are usually benign, but malignant transformation can occur. Symptomatology depends on the involvement of the surrounding tissues or the mass effect of the tumor. We describe a case of a 28-year-old man who initially presented with right iliac fossa pain associated with radiating pain over the anterior and lateral aspect of his right knee. Following subsequent investigations, we found a retroperitoneal schwannoma of the right lateral femoral cutaneous nerve. The key to our diagnosis was the referred pain to his right knee, which gave us a clue of possible neuropathic pain. Our patient highlights the need to consider a unified diagnosis when faced with an incongruent set of symptoms. Magnetic resonance imaging is the diagnostic modality of choice for the diagnosis of schwannomas. Treatment is directed towards symptomatic control. Surgery, radiation, and, in rare instances, chemotherapy are the major treatment modalities employed.
