Incidental dedifferentiated mediastinal liposarcoma on F-18-fluciclovine PET/CT
Fat-containing mediastinal masses, particularly mediastinal liposarcomas, are rare neoplasms that can grow to large sizes before becoming symptomatic and may be incidentally found on radiology examinations.In this case report, a 67-year-old male with a history of prostate cancer status post prostatectomy presented for an F-18-fluciclovine PET/CT for a rising, clinically detectable PSA and indeterminate pelvic lymph nodes seen on multiparametric MRI of the prostate. No local tumor recurrence or metastatic disease from prostate cancer was identified, but the PET/CT demonstrated a mixed soft tissue and fat density prevascular...

Correlation between hyperhemoglobinemia and pseudosubarachnoid hemorrhage
Subarachnoid hemorrhage (SAH) is a severe cerebrovascular condition. Some cases present with typical signs of SAH on head computed tomography (CT), whereas other cases have a condition known as pseudo-SAH, with no bleeding actually present. In our clinical experience, we noted that cases of hyperhemoglobinemia often also had pseudo-SAH. Here we investigated the relationship between hyperhemoglobinemia and pseudo-SAH and explored the underlying mechanism. (Source: Clinical Imaging)

Magnetic resonance imaging of tubal ectopic pregnancy: correlation with intraoperative findings
Ectopic pregnancy is defined as a pregnancy that occurs outside of the uterine cavity (ACOG Committee on Practice Bulletins, 2018 [1]). Ectopic pregnancy is occasionally diagnosed with MRI. Particularly, when ultrasound is nondiagnostic, it is essential that radiologists are able to recognize findings of ectopic pregnancy on MRI in the emergent setting. This novel case report demonstrates specific MR imaging signs recently proposed in the literature to help identify a tubal gestational sac, the most common type of ectopic pregnancy, and is the first reported case demonstrating intraoperative correlation with MRI findings o...

Lymphangitic spread of invasive lobular carcinoma to the contralateral breast
Breast cancer typically spreads primarily to regional lymph nodes and subsequently to distant sites via hematogenous routes. Occasionally metastasis can occur through lymphangitic spread, usually to the lungs, resulting in lymphangitic carcinomatosis. Lymphangitic spread of several malignancies have been reported at other sites in the body with varying degrees of clinical significance. In this case report, we describe a rare case of lymphangitic spread of invasive lobular carcinoma to the contralateral breast identified on imaging as significant background enhancement without a discrete suspicious mass.

Articular cartilage is a complex tissue with unique properties that are essential for normal joint function. Many processes can result in cartilage injury, ranging from acute trauma to degenerative processes. Articular cartilage lacks vascularity, and therefore most chondral defects do not heal spontaneously and may require surgical repair. A variety of cartilage repair techniques have been developed and include bone marrow stimulation (microfracture), osteochondral autograft transfer system (OATS) or osteochondral allograft transplantation, autologous chondrocyte implantation (ACI), matrix-assisted chondrocyte implantatio...

Tissue marker placement after image-guided breast biopsy has become a routine component of clinical practice. Marker placement distinguishes multiple biopsied lesions within the same breast, prevents re-biopsy of benign lesions, enables multi-modality correlation, guides pre-operative localization and helps confirm surgical target removal. Numerous breast tissue markers are currently available, with varied shapes, composition, and associated bio-absorbable components. This review serves to familiarize the breast interventionalist with the tissue markers most widely available in the United States today and to provide guidan...

Currently, teleradiology is most frequently used in the United States to supplement shortages of radiologists and provide overnight and weekend coverage to allow real-time interpretation of studies [2].

Curbside consults: Practices, pitfalls and legal issues
“Curbside consults” are informal opinions provided by one physician to another. In radiology, it often refers to opinions rendered on imaging performed at outside facilities and has evolved from being a targeted response to a discrete clinical question to a complete over-read in recent years. Gi ven that the consults are usually sought for patients with complex conditions, the potential for error increases with informal reads, often due to the time constraint and lack of adequate information. Misinterpretations and inaccurate documentation by the referring clinician are also more likely. (Source: Clinical Imaging)
