Incorporation of internal iliac arteries as target vessels during physician-modified fenestrated branched endovascular repair of pararenal abdominal aortic aneurysm with concomitant bilateral short common iliac artery aneurysms.

This report describes an alternative endovascular approach to iliac branch devices for treatment of an abdominal aortic aneurysm with concomitant bilateral short common iliac aneurysms. The short distance between the renal arteries and internal iliac artery origins made the addition of distal iliac branch devices to the proximal fenestrated stent graft challenging. We elected to perform physician-modified fenestrated branched endovascular repair, using four fenestrations for the visceral and renal arteries and an additional two directional branches for the bilateral internal iliac arteries. The patient recovered uneventfully, and the 24-month follow-up imaging shows successful aneurysm exclusion with patent internal iliac artery branches.

Hodgkin lymphoma masquerading as perforated gallbladder adenocarcinoma: A case report.

BACKGROUND: There are several case reports of acute cholecystitis as the initial presentation of lymphoma of the gallbladder; all reports describe non-Hodgkin lymphoma or its subtypes on histopathology of the gallbladder tissue itself. Interestingly, there is no description in the literature of Hodgkin lymphoma causing hilar lymphadenopathy, inevitably presenting as ruptured cholecystitis with imaging mimicking gallbladder adenocarcinoma. CASE SUMMARY: A 48-year-old man with a past medical history of diabetes mellitus presented with progressive abdominal pain, jaundice, night sweats, weakness, and unintended weight loss for one month. Work-up revealed a mass in the region of the porta hepatis causing obstructions of the cystic and common hepatic ducts, gallbladder rupture, as well as retroperitoneal lymphadenopathy. The clinical picture and imaging findings were suspicious for locally advanced gallbladder adenocarcinoma causing ruptured cholecystitis and cholangitis, with metastases to retroperitoneal lymph nodes. Minimally invasive techniques, including endoscopic duct brushings and percutaneous lymph node biopsy, were inadequate for tissue diagnosis. Therefore, this case required exploratory laparotomy, open cholecystectomy, and periaortic lymph node dissection for histopathological assessment and definitive diagnosis. Hodgkin lymphoma was present in the lymph nodes while the gallbladder specimen had no evidence of malignancy. CONCLUSION: This clinical scenario highlights the importance of histopathological assessment in diagnosing gallbladder malignancy in a patient with gallbladder perforation and a grossly positive positron emission tomography/computed tomography scan. For both gallbladder adenocarcinoma and Hodgkin lymphoma, medical and surgical therapies must be tailored to the specific disease entity in order to achieve optimal long-term survival rates.

Atypical presentation of necrotising autoimmune myopathy.

Necrotising autoimmune myopathy (NAM) is characterised by a common phenotype of profound symmetrical proximal muscle weakness, elevated creatine kinase levels, irritable myopathy on electromyography and histological findings of myocyte necrosis and regeneration without remarkable inflammation. NAM is associated with autoimmune antibodies including anti-3-hydroxy-3-methylglutaryl-coenzyme receptor, which is strongly associated with statin use. We report a case of statin-associated NAM with an atypical presentation of severe oropharyngeal dysphagia and no remarkable proximal muscle weakness at initial presentation but with rapid progression to severe quadriparesis in weeks. This case expands the spectrum of presentation patterns of this rare disease and highlights the need for a high index of suspicion in patients with a remote history of statin use.
