ABSTRACT

De-differentiated primary mediastinal liposarcomas account for less than 1% of all liposarcoma pathology. We report the case of an 82-year-old male who was suffering from progressive dysphagia, shortness of breath, and dysphonia for a period of 2 months. A CT scan of the chest with contrast revealed a large heterogeneously enhancing posterior mediastinal mass extending into the posterior soft tissues of the neck, abutting bilateral carotid arteries, and displacing the trachea and esophagus. Treatment chosen for our patient was surgical resection followed by adjuvant radiation therapy which resolved the patient's presenting symptoms. The insights gained through the diagnosis, management, and treatment of our patient can be utilized to approach this type of rare neoplasm.

ABSTRACT

We present a case of a female who presented with the acute onset of neurological changes within 24 hours of receiving her third, or booster, dose of the mRNA Moderna (Cambridge, Massachusetts) coronavirus disease 2019 (COVID-19) vaccination. Her clinicoradiological findings were most consistent with posterior reversible encephalopathy syndrome (PRES). Although PRES has been reported with severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection, this raised suspicion of a possible vaccine-induced PRES with her only confounder being hypertension managed with a beta-blocker. Extensive workup for other entities associated with PRES, including infection, autoimmune, paraneoplastic syndrome, and alcohol were unrevealing. Thus far, there have not been any reports of PRES post mRNA vaccination. We encourage providers to report similar cases with neurological manifestations post mRNA vaccination to the vaccine adverse event reporting system (VAERS). Timely diagnosis and treatment of PRES may help minimize any irreversible neurological sequelae.

ABSTRACT

OBJECTIVE: Chronic venous insufficiency (CVI) has an increased prevalence among obese individuals with body mass indices (BMI) over 30. A safe, efficacious, and evidence-based recommended treatment for CVI due to superficial venous reflux (SVR) in great saphenous veins (GSVs), small saphenous veins (SSVs), accessory saphenous veins (ASVs), and reflux in the perforator veins (PVs) is endovenous thermal ablation (EVTA). We sought to identify if BMI is an independent risk factor for recanalization after EVTA. METHODS: All patients with CVI were initially managed conservatively, and those with pathologic SVR refractory to compression therapy were offered EVTAs depending on the site of reflux. Sonographic confirmation of SVR was defined as >500 milliseconds of reflux in the GSVs, SSVs, and ASVs and a diameter >4 mm. PV reflux was confirmed as >350 milliseconds of reflux and a diameter >2.5 mm. All patients received a follow-up duplex ultrasound 1 week after the procedure, every 3 months for the first year, and every 6 months thereafter. Multivariate analysis with logistic regression was performed regarding patients' age, ablation modality (laser vs radiofrequency ablation), vein location and laterality, BMI, and recanalization. RESULTS: From 2013 to 2018, 9739 endovenous ablations were performed on 3070 patients. Endovenous laser was used in 3862 procedures and radiofrequency ablation in 5831 procedures. Veins treated with EVTA were distributed as follows: 6182 GSVs, 2509 SSVs, 597 ASVs, and 451 PVs. The mean patient age was 61.1 years (15-99, standard deviation [SD] ±15.6) with a mean BMI of 31.2 kg/m2 (13.7-69.5, SD ±7.3). A total of 68.4% patients were women and 31.4% men. The mean follow-up was 25.8 months (0-65.9, SD ±12.9). Multivariate statistical analysis with logistic regression was used to determine potential statistical significance between BMI and vein recanalization after EVTA. Overall, obese patients experienced more recanalizations than nonobese patients (P = .032), with an average BMI of 33 kg/m2 for recanalizations. PVs were statistically more likely to recanalize than any other vein (P = .0001). A secondary analysis was performed with the exclusion of PVs, due to their five times increased risk of recanalization, and showed no significant difference of recanalization across all BMI subgroups (P = .127). CONCLUSIONS: BMI does not predict recanalization risk after EVTA, except for ablations performed on PVs.

ABSTRACT

The most common subtype of colon cancer is colorectal adenocarcinoma. Compared with other subtypes, such as signet-ring and mucinous, colorectal adenocarcinoma has been found to have lower rates of metastasis. Approximately 20% of colorectal cancer cases present with metastatic disease on initial evaluation. The most common locations for metastasis are the liver, lung, peritoneum, bone, and extra-regional lymph nodes. Metastatic disease to the skeletal muscle, however, is considerably rare. We present a clinical case of a 52-year-old female found to have a cystic iliopsoas muscle metastasis from rectosigmoid adenocarcinoma, initially classified as an infected fluid collection.
