Optimal diagnosis of splenic vein thrombosis: brief clinical report.

The presence of splenic vein thrombosis is sometimes very difficult to diagnose. We present a patient in whom the splenic vein was thought to be patent by ultrasound and conventional celiac angiography. Because of high clinical suspicion and continued bleeding, he underwent a selective intra-arterial digital splenic angiogram. The venous phase clearly showed proximal (hilar) splenic vein occlusion with filling via collaterals in real time. Splenectomy confirmed the diagnosis. We believe that a selective intra-arterial digital splenic angiogram is the radiographic study of choice for suspected splenic vein thrombosis.

'Page kidney'. Hypertension caused by chronic subcapsular hematoma.

Conditions analogous to an experimental model of hypertension described by Page in 1939 are called "Page kidney." In chronic subcapsular hematoma, the most common clinical counterpart to Page's model of renal parenchymal compression, a review of the literature reveals that hypertension is usually cured by nephrectomy, but is seldom cured by mere evacuation of the hematoma. To our knowledge, no patient remaining hypertensive after evacuation has undergone nephrectomy. In the patient described herein, a liquified subcapsular hematoma reaccumulated after it was drained percutaneously, and therefore it had to be evacuated surgically. Persistent renin-mediated hypertension, however, prompted curative nephrectomy. The response to more prolonged percutaneous drainage might have guided more effective initial surgery.

Is there still a role for knee arthrography?

To assess the continued value of arthrograms in the wake of arthroscopic diagnosis, an analysis of arthrographic data on 240 knees was carried out. The accuracy, sensitivity, and specificity of the arthograms were compared with the arthroscopic findings for each knee. For meniscal lesions, the arthrogram is reasonably accurate. An algorithm is presented that defines the relative roles of arthrography and arthroscopy.

Preoperative radiographic evaluation of hypernephroma.

Computed tomography (CT) of hypernephroma is compared with arteriography in terms of accuracy and cost. Computed tomography is shown to be as accurate as arteriography with respect to identification and diagnosis of most renal masses. In selected cases, it has been more accurate than arteriography because of the definition of adjacent retroperitoneum and tumor extent. Most of our patients having CT have required supplemental inferior vena cavography preoperatively, and a few selected cases have required arteriography. Nevertheless, the renal arteriogram can be omitted in most cases because CT is effective in diagnosing and staging hypernephroma, in addition to being noninvasive and more cost-effective.

Correlations of arthrography with arthroscopy.

Arthrography and arthroscopy were compared on a prospective basis in 100 consecutive and unselected knees, all in patients who underwent arthrography, arthroscopy, and surgery. Arthroscopy was found to be more accurate than arthrography in the diagnosis of medial and lateral meniscus and anterior cruciate ligament lesions. Because of its easy availability and relatively low cost, arthrography continues to be a useful extension of the physical examination of the knee, serving as a further diagnostic screening technique. However, arthroscopy is recommended in all patients prior to surgery because it provides more complete and more accurate delineation of intra-articular lesions.

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.

MR and CT appearance of ruptured intracranial dermoid tumors.

Intracranial dermoid tumors have characteristic MR and CT appearances. Rupture of an intracranial dermoid produces a dramatic MR and CT appearance. Two cases of ruptured intracranial dermoid tumors are presented, one with rupture into the subarachnoid space, another with rupture into the ventricles. MR and CT findings are included.
