Imaging the Inferior Vena Cava: A Road Less Traveled

A broad spectrum of congenital anomalies and pathologic conditions can affect the inferior vena cava (IVC). Most congenital anomalies are asymptomatic; consequently, an awareness of their existence and imaging appearances is necessary to avoid misinterpretation. Imaging also plays a central role in the diagnosis of Budd-Chiari syndrome secondary to membranous obstruction of the intrahepatic IVC. Primary malignancy of the IVC is far less common than intracaval extension of malignant tumors arising in adjacent organs, and imaging can accurately help determine the presence and extent of tumor thrombus, information that is crucial for surgical planning. However, the radiologist should be aware that artifactual filling defects at computed tomography and magnetic resonance imaging can mimic true thrombus in the IVC and must be able to differentiate true from pseudo filling defects. Other imaging findings such as flat IVC and early enhancement of the IVC are useful in limiting the differential diagnosis. Familiarity with the imaging features of the various congenital and pathologic entities that can affect the IVC is paramount for early diagnosis and management.

Combined transmesocolic and left paraduodenal hernia: barium, CT and MRI features

Internal hernia is difficult to diagnose clinically because the symptoms are often non-specific. Although this entity is an uncommon cause of small-bowel obstruction, prompt diagnosis is essential for a favorable outcome. We report the barium, CT and MRI features of a rare case of non-obstructing combined transmesocolic and left paraduodenal hernia.

Antenatal MRI Diagnosis of Massive Subchorionic Hematoma: A Case Report

Massive subchorionic hematoma is a large maternal blood clot, which separates the chorionic plate from the villous chorion [Kojima K, et al: Fetal Diagn Ther 2001;16:57–60]. It is an uncommon condition associated with poor perinatal prognosis and intrauterine growth retardation [Tan WH, et al: Fetal Diagn Ther 1997;76:381–383, Nishijima K, et al: Fetal Diagn Ther 2005;20:23–26]. Ultrasound may not be able to differentiate this condition from other placental abnormalities [Kojima K, et al: Fetal Diagn Ther 2001;16:57–60]. We report a case of massive subchorionic hematoma where the antenatal diagnosis was made on MRI.

Imaging spectrum of pediatric orbital pathology: A pictorial review

A wide spectrum of pediatric orbital disorders can occur in the pediatric age group. Cross-sectional imaging plays an important role in the diagnosis and management of these patients. We reviewed our imaging record and collected representative cases of pediatric orbital pathology. The purpose of this pictorial essay is to illustrate the imaging features of various orbital lesions encountered in children.

Proptosis with orbital soft tissue and bone changes and unilateral papilloedema: unusual presentation of POEMS syndrome

POEMS syndrome is a rare manifestation comprising of polyneuropathy, organomegaly, endocrinopathy, monoclonal gammopathy and skin changes. Orbital involvement in this syndrome is rare and manifestation with proptosis, even rarer. The imaging features in Poems syndrome and rarity of various features in our case are being highlighted here.

Meningioma of the floor of the anterior cranial fossa with bilateral intraorbital extension

We report meningioma of the floor of the anterior cranial fossa with bilateral, symmetrical intraorbital extension, describing the findings on plain films and CT.
