24. Venous Malformation in the Breast: Imaging Features to Avoid Unnecessary Biopsies or Surgery

Author

Abstract

Venous malformations are now categorised under the broad heading of slow flow vascular malformations. They comprise abnormally dilated venous channels that fail to involute. These may be superficial or deep in location. We describe two cases of venous malformation in breast. Both the patients presented with focal pain in one breast. On mammography, they appeared as equal density well circumscribed soft tissue masses. No sonographic correlate was found on initial ultrasound examination. Subsequent ultrasonography performed by an experienced radiologist with minimal probe pressure revealed dilated veins. On the basis of imaging findings, the diagnosis of venous malformation was established.

36. Temporal Evolution of Signal Alterations in the Deep Gray Nuclei in term Neonates With Hypoxic-Ischemic Brain Injury: A Comprehensive Review.

Abstract

The deep gray nuclei are paired interconnected gray nuclei comprising the basal ganglia and thalami. Injury to the deep gray nuclei secondary to hypoxic-ischemic injury is associated with poor short- and long-term clinical outcomes. The signal changes following hypoxic-ischemic injury are dynamic and evolve over a period of time from injury to resolution. Radiologically relevant events following hypoxic-ischemic injury include the onset of anaerobic metabolism immediately following hypoxic-ischemic injury, increase in cytotoxic edema followed by its resolution, and the onset and progression of neuronal necrosis and gliosis. Appearance of lactate peak on proton spectroscopy is the initial radiologic evidence of hypoxic-ischemic injury. Diffusion-weighted imaging has the highest prognostic value and pseudo-normalizes following 1 week of hypoxic-ischemic injury. Recommended timing for magnetic resonance imaging (MRI) is between 4 and 7 days. MR imaging performed between 1 and 6 months underestimates the extent of injury because radiologic changes are subtle. This review provides a detailed timeline of radiologic abnormalities in the deep gray nuclei following hypoxic-ischemic injury. [ABSTRACT FROM AUTHOR]

38. The role of 'penumbra sign' and diffusion-weighted imaging in adnexal masses: do they provide a clue in differentiating tubo-ovarian abscess from ovarian malignancy?

Abstract

Purpose: To evaluate the role of "penumbra sign", diffusion-weighted imaging (DWI), and the apparent diffusion coefficient (ADC) value in differentiating tubo-ovarian abscess (TOA) from ovarian malignancy. Material and methods: Thirty-six patients with 50 adnexal masses (tubo-ovarian abscess, n = 24; ovarian malignancy, n = 26), who underwent magnetic resonance imaging (MRI) with DWI, were retrospectively evaluated. "Penumbra sign" (hyperintense rim on T1W images), diffusion restriction, and mean apparent diffusion coefficient (ADC) values from cystic (c-ADC) and solid (s-ADC) components were evaluated for all the masses. Results: "Penumbra sign" on T1W images was significantly more common in the TOA group (n = 21, 87.5%) than in the ovarian malignancy group (n = 2, 7.7%) (p < 0.001). Similarly, diffusion restriction in the cystic component was more frequent in the TOA group (n = 24, 100% vs. n = 2, 10.5%; p < 0.001). In contrast, diffusion restriction in the solid component was more common in the ovarian malignancy group (n = 5, 20.8% vs. n = 26, 100%; p < 0.001). The mean c-ADC value was significantly lower in TOAs (p < 0.001). A c-ADC value of 1.31 × 10-3 mm2/s may be an optimal cut-off in distinguishing TOAs from ovarian malignancies. Conversely, the mean s-ADC value was significantly lower in the ovarian malignancy group (p < 0.001). An s-ADC value of 0.869 × 10-3 mm2/s may be an optimal cut-off in differentiating ovarian malignancies from TOAs (p < 0.001). ROC curve analysis showed that c-ADC values had a higher diagnostic accuracy than s-ADC values. Conclusions: "Penumbra sign" on T1W images, diffusion characteristics, and ADC values provide important clues in addition to conventional MR imaging features in differentiating TOA from ovarian malignancy.

39. Cervical extension of pancreatic pseudocyst: An unusual cause of neck stiffness and dysphagia

Abstract

Pancreatic pseudocyst is a common complication that can occur following acute or chronic pancreatitis. Commonly, they are peripancreatic in location. Rarely, they can extend to the mediastinum, and further extension to the neck is even rarer. A 55-year-old man who presented with neck stiffness and dysphagia and on imaging, was found to have a cystic lesion in the neck. Aspiration of the lesion revealed raised amylase levels suggestive of a pancreatic pseudocyst.&nbsp

41. Magnetic resonance imaging of rhino-orbito-cerebral mucormycosis: a pictorial review.

Abstract

Rhino-orbito-cerebral mucormycosis is a potentially fatal disease requiring early magnetic resonance imaging (MRI) for disease evaluation and timely detection of intracranial complications. Angio-invasive nature leading to necrosis and infarction is the hallmark of mucormycosis. The disease follows a fulminant course extending from the paranasal sinuses to involve the orbit, deep neck spaces, skull base, facial bones, and intracranial compartment. Loss of vision either due to direct extension into the orbit or optic nerve infarction adds to disease morbidity. Prompt MRI using dedicated sequences can help in assessing the exact disease extent including early osseous and intracranial changes, which aid in precise disease management. [ABSTRACT FROM AUTHOR]
