A 48-year woman was found to have bilateral axillary nodal microcalcifications on screening mammogram; a new finding compared to the prior mammogram done about 8 years ago. Combining the new finding with the amorphous and fine morphology of the microcalcifications, deemed it suspicious. In the absence of a definite benign cause, that could be attributed to this finding, biopsy was performed. Histology from the bilateral axillary node was reported to be benign with calcifications identified within granulomas. There are only a few cases with bilateral axillary nodal microcalcifications reported in the literature till date. Most of these are from ovarian cancer or related to chrysotherapy for rheumatoid arthritis. Our case is distinct from them as this rare finding was not due to any of the known etiologies and the morphology is quite different from the known granulomatous causes. As we report this rare case, we also revisit the causes of axillary nodal microcalcifications. Familiarity with this subject can help the reporting radiologists to avert an invasive procedure like biopsy in some cases, if the cause of benignity can be confidently identified.

Solitary axillary lymph node metastasis from ovarian cancer is rare. A 74-year-old woman who had undergone hysterectomy and bilateral salpingo-oophorectomy for ovarian cancer 2 years ago presented to our hospital with enlarged axillary lymph node. 18F-FDG PET/CT revealed left axillary lymphadenopathy with an SUVmax of 8.

Paradoxical embolism occurs when a clot originates in the venous system and traverses through a pulmonary or intracardiac shunt into the systemic circulation, with a mortality rate of around 18%. The risk factors for arterial embolism and venous thrombosis are similar, but different disease entities can lead to a hypercoagulable state of the blood, including antithrombin III (AT III) deficiency. We report the case of a 43-year-old man with a massive central pulmonary embolism with a rider embolus and concomitant aortic arch embolism with involvement of the brachiocephalic trunk, bilateral subclavian and axillary arteries, and the right vertebral artery, followed by a secondary ischaemic stroke.

Background: Endoscopic thoracic sympathectomy is a well-known and effective treatment for palmar and axillary primary hyperhidrosis (PHH). Its most frequent drawback and the main complaint among patients who underwent surgery is the appearance of compensatory sweating (CS). To date, no long-term studies using internationally standardized tools have assessed the efficacy and impact of this surgery on patients.

Background: Stroke is one of the severe complications following surgery in patients with acute type A aortic dissection (ATAAD). This study investigates the relationship between the preoperative serum uric acid to serum creatinine ratio (SUA/Scr) and postoperative stroke in patients undergoing total arch replacement with elephant trunk implantation for aortic dissection.
Methods: We included ATAAD patients who were hospitalized and underwent surgery between June 1, 2015 and June 1, 2023, with complete clinical information.

Background: Regional anesthesia techniques that provide analgesia to the entire lateral abdomen are limited. We present a modified external oblique intercostal block for complete lateral abdominal analgesia with a single injection.
Case: We performed a modified version of the external oblique intercostal block unilaterally at the tenth rib along the mid-axillary line in three patients undergoing robot-assisted partial nephrectomy (two single injections, one catheter placement) and tested the technique on a cadaver with 20 ml of dye bilaterally.
