Primary and secondary pulmonary artery neoplasia mimicking acute pulmonary embolism.
Two cases of rare pulmonary neoplastic lesions (primary pulmonary artery sarcoma and pulmonary carcinosarcoma) directly involving the pulmonary artery and presenting with findings mimicking acute pulmonary embolism are discussed. Although this represents an unusual presentation for these two lesions, they should be included in the differential diagnosis of acute pulmonary embolism in patients presenting with somewhat atypical clinical, isotopic, and radiological features. Serial lung scans followed by angiography will prove useful in arriving at the correct diagnosis.

Traumatic thenar ischemia.
A case of posttraumatic digital ischemia involving the thenar portion of the hand is presented and the differential diagnosis of hand ischemia is discussed. The importance of obtaining an occupational history for assessment of possible hand trauma is emphasized. Angiography can confirm the diagnosis of posttraumatic arterial injury and will localize thrombosis or aneurysms for possible surgical repair.

Ossicle of the meniscus.
Two patients with an ossicle of the meniscus are described. Radiologic differentiation from osteochondral loose body or chondrocalcinosis can be made by its ossified appearance and its location within the meniscus. Correct diagnosis is important so that unnecessary surgery is avoided and a protracted search for a free fragment is not carried out.

Roentgen anatomy of the posterior horn of the lateral meniscus.
The roentgen anatomy of the posterior horn of the lateral meniscus of the knee is presented with particular attention to the relationships between the popliteus tendon, joint capsule and meniscus. The popliteus tendon creates a tunnel as it passes obliquely through the posterior half of the meniscus creating two walls (medial and lateral) and a roof (superior attachment) and a floor (inferior attachment). The boundaries are readily visible on the double-contrast knee arthrogram. Familiarity with these relationships aids in the diagnosis of meniscal injuries.

Modification of a serial film changer for frontal magnification angiography.
A movable carriage was designed and built for a Franklin film changer to facilitate routine serial 2 times magnification. This simple device permits magnification angiography without major equipment purchases or room alterations.
