Abstract: Adrenal collision tumors are rare clinical entities referring to separate coexisting adjacent tumors involving an adrenal gland with sharp demarcation between the two and without a substantial histologic admixture at the interface. Most of the adrenal collision tumors described are combinations of adenoma and metastasis or adenoma and myelolipoma. We report two cases of a 63-year-old male and a 76-year-old female patient with a presumable exceedingly rare adrenal hemangioma-adenoma collision tumor. To our knowledge, only two reports of a collision tumor comprising an adrenal hemangioma and an adenoma have been described in literature.

Abstract: Serious side effects of vaccinations are not common, though rare complications can occur. We present a case of one such uncommon side effect, influenza vaccine-related subacromial/subdeltoid bursitis. A 72-year-old female presented with severe shoulder pain following influenza vaccination. The pain persisted for up to two months despite conservative measures, and MRI demonstrated moderate subacromial/subdeltoid bursitis. Vaccine-related shoulder dysfunction includes a range of pathology, from osteonecrosis to bursitis, which will be reviewed in this report. Recognition of infrequent vaccine-related musculoskeletal pathology is important to prevent delay of diagnosis.

Abstract: Anastomosing hemangiomas are a rare subtype of benign vascular hemangioma which most commonly arise in the genitourinary tract and retroperitoneum. In only a small number of reports has this entity been shown originating within the liver parenchyma. Despite their benign behavior, on contrast-enhanced computer tomography and magnetic resonance imaging studies anastomosing hemangiomas can demonstrate enhancement characteristics similar to primary and metastatic liver lesions. This case report highlights the imaging features of this entity and provides a brief review of the limited literature that exists on this rare hepatic lesion.

Abstract: Subperiosteal hematoma of the orbit is an uncommon radiologic finding. Most typically, the hemorrhage is in the superior aspect of the orbit, however, location within the orbit may vary. Subperiosteal hematoma of the orbit may be associated with trauma. Nontraumatic etiology has also been well documented. We present a series of three cases, to illustrate typical and atypical radiologic findings of subperiosteal hematoma of the orbit, both traumatic and nontraumatic. Review of the pertinent radiologic literature and its relation to the cases presented here is also provided.
