Ultrasonographic findings associated with uterine migrating grass seeds in eleven dogs

Numerous locations have been reported for vegetal foreign body migration. However, urogenital migration has rarely been documented. In this retrospective study, the ultrasonographic features associated with intrauterine migrating vegetal foreign bodies (grass seeds) are described in one intact and ten ovariectomized bitches. The most common ultrasonographic finding was focal and mild ampullary dilation of the uterus, containing the foreign body outlined by scant intraluminal fluid. There were no changes seen to the uterine wall, except in one dog with uterine perforation, confirmed at surgery. The remainder of the uterus had a normal appearance in 8/11 dogs, while there was a small amount of intraluminal fluid in 2/11 cases. Mild, focal steatitis around the focal dilation of the uterus segment containing the foreign body was observed in one case. The subtlety of these findings suggests that the ultrasonographic diagnosis of uterine grass awns can be challenging. This underlines a discrepancy with other reported migration sites commonly associated with marked inflammation.

Migration of a swallowed needle into the cervical spine: case report

Foreign body migration into the cervical spine is rare. Only 3 prior reports of needle migration into the cervical spine exist in the literature. Here, the authors report one such case, where the migrated needle narrowly avoided the thecal sac and vertebral artery. To the authors’ knowledge, this is the first report of a migrated swallowed foreign body in the cervical spine.

Air gun orbitocranial penetrating injury: emergency endovascular treatment and surgical bypass following pellet migration to middle cerebral artery: case report

The authors describe a 14-year-old boy presenting with an orbitocranial penetrating injury (OPI) from a metallic air gun pellet to the left eye who developed hemiparesis and speech difficulty due to migration of the pellet to the left middle cerebral artery. They highlight the potential complications associated with both OPIs and intravascular foreign body migration and occlusion by describing the patient’s presentation, results of imaging evaluation, and the combined endovascular treatment and extracranial-intracranial bypass, which resulted in rapid restoration of blood flow and full neurological recovery with intact vision. Based on this case and a review of the literature on intracranial foreign body migration with resultant vascular occlusion, the authors recommend that complex OPIs be treated at centers that offer both neuroendovascular and neurovascular surgical capabilities on an urgent basis to manage both the primary injury and potential secondary vascular compromise.
