Spontaneous transverse colon volvulus in a patient with Duchenne muscular dystrophy: An unreported complication.

A 22-year-old male patient with Duchenne muscular dystrophy (DMD) and chronic constipation presents to the emergency room with severe abdominal pain and hive closed to feces and gas. Contrast-enhanced computed tomography of the abdomen demonstrates mechanical ileus due to volvulus of the transverse colon: torsion of the transverse mesocolon is confirmed and subtotaly colectomy is performed, revealing multiple ischemic areas with focal perforations. DMD is frequently associated with gastrointestinal motility disorders, including chronic constipation and life-threatening conditions like intestinal pseudo-obstruction and sigmoid volvulus. To date, transverse colic localization of volvolus represents an unreported condition among patients with DMD.

Aortic intramural hematoma and classic aortic dissection: two sides of the same coin within the acute aortic syndrome for an interventional radiologist.

Management of acute type B aortic intramural haematoma (AIH) still represents a challenging issue. Although most resolve spontaneously or with conservative therapy, several cases of AIH may complicate into classic aortic dissection with subsequent risk of aortic rupture and visceral malperfusion, thus needing urgent or preemptive thoracic endovascular aneurysm repair (TEVAR). Despite the long-term aorta-related survival, TEVAR might lead to graft obstruction, migration, infection, stroke/paraplegia, visceral ischemia, endoleak and, last but not least, retrograde aortic dissection (AD), frequent in the acute phase and associated with a high mortality risk. In order to highlight such a close relationship between AIH and AD and the possibility to perform endovascular treatment, we report the experience of an adult female patient with an aortic intramural haematoma evolving into a classic aortic dissection. Despite successful thoracic endovascular aneurysm repair (TEVAR), our patient developed an aortic dissection type A at one month with subsequent indication for cardiac surgery still representing the elective approach in case of pathologies including the ascending aorta. Thus, the aim of our discussion is to create a debate on the most appropriate management for the treatment of descending AIH.

Giant sacral schwannoma excised under intraoperative neuromonitoring in an elderly patient: case report.

Schwannomas are mainly benign tumors arising from the Schwann cells of the peripheral nerve sheath. These tumors can often be associated with non-specific symptoms, such as abdominal heaviness. In this article, we present a detailed description of the surgical management of a giant sacral schwannoma in an elderly patient, for which intraoperative neuromonitoring made it possible to distinguish easily the nerves of the sacral plexus from which the tumor originated and to remove it without complications. Treatment of these rare and symptomatic giant tumors is still a challenge for surgeons; to treat adequately these tumors; a multidisciplinary approach is required to ensure an optimal therapeutic approach to reduce the risk of recurrence and, on the other hand, is not associated with unnecessary iatrogenic neurological damage.
