Radiation induced cholecystitis is a known but rare complication of Yttrium90 (Y90) radioembolization of hepatic tumors due to nontarget embolization. Many documented cases of radiation induced cholecystitis have been treated with cholecystectomy, which is significant given the typical patient population undergoing radioembolization tends to be of higher surgical risk. Here, we present a case of a 68 year old male who developed radiation induced cholecystitis status post hepatic radioembolization that resolved with conservative management alone. This case highlights that radiation induced cholecystitis may be successfully and safely treated conservatively.

Geniculate artery embolization is a treatment option for refractory knee osteoarthritis in patients unable to receive total knee arthroplasty. This case report describes two patients for whom pedal access was used to embolize the geniculate arteries due to challenging groin anatomy secondary to significant comorbidities (morbid obesity, proximal atherosclerosis). Both patients achieved marked pain relief and enhanced knee function at 1-month follow-up. These cases suggest that pedal access is a viable alternative, offering a promising approach for patients with unfavorable anatomy and comorbidities that make groin access impractical. Further research is needed to validate these findings in larger patient populations. Article published online: 27 January 2025 © 2025. The Author(s).

Solitary plasmacytoma of bone (SPB) is a rare plasma cell malignancy that most often presents with localized pain. This case describes a 70-year-old female with a pathologic humeral fracture due to a large, hypervascular SPB. The tumor was assumed to be a metastatic lesion, and preoperative embolization was performed to minimize intraoperative blood loss, followed by tumor debulking and total shoulder arthroplasty. The total estimated blood loss was limited to 100cc, and the patient was returned to baseline functional status with full shoulder range of motion at 6 months postop. Literature on embolization of appendicular plasmacytomas is sparse; however, this case supports its efficacy. We recommend considering preoperative embolization as an adjunctive therapy for all hypervascular bone tumors requiring surgical management, regardless of origin.

A spontaneous adrenal hemorrhage is a rare complication occurring in the setting of interventional radiology procedures. Here, we present the case of a 73-year-old male who underwent CT-guided drainage of a periduodenal collection. During the procedure, he developed sudden onset left back pain and hypertension, which revealed a left adrenal gland hemorrhage on CT imaging. Potential mechanisms for this complication include a physiological stress response, procedure-associated hypercoagulability, and direct trauma to the adrenal gland. Moreover, an adrenal hemorrhage should be monitored closely as it can lead to severe clinical consequences requiring treatment with IV analgesics and antihypertensives.
