Fibroadenoma in male breast: case report and literature review.

We report a rare case of mammary fibroadenoma in a 75 year old male patient with emphasis on imaging findings and review of the previously reported cases.

Presacral extramedullary hematopoiesis: report of a case and review of the literature.

Extramedullary hematopoiesis is manifested by several clinical hematological disorders. Its localization to presacral space as mass is extremely rare. We report one such case in a patient with hereditary spherocytosis.

Radiological findings in Birt-Hogg-Dubé syndrome: a rare differential for pulmonary cysts and renal tumors.

Birt-Hogg-Dubé syndrome is a rare disorder characterized by cutaneous hair follicle tumors, pulmonary cysts, and renal tumors. We report a case of a 63-year-old male patient with this syndrome. The radiological findings seen with this syndrome are described.

Collar osteophytes: a cause of false-positive findings in bone scans for hip fractures.

Objective: A retrospective review of our radiology database revealed five elderly patients, seen over a 12-month period, whose findings were judged positive for hip fractures on the basis of their bone scans, but whose MR imaging findings were negative.

Conclusion: The presence of collar osteophytes around the femoral neck caused a false diagnosis of hip fracture for these patients, as revealed on radionuclide bone scans. CT or MR imaging correlation is needed where collar osteophytes may have caused an incorrect diagnosis of hip fracture based on a bone scan.
