Article Synopsis
- - Sea spiders (Pycnogonida) are a unique group of marine animals related to horseshoe crabs, but there's limited information on their anatomy and biology, particularly regarding reproduction.
- - This research focuses on the male reproductive system of the sea spider P. femoratum, detailing its U-shaped testis with specific features like pedal outgrowths and reduced reproductive sinus, which supports sperm development.
- - The study highlights the structure of sperm from P. femoratum, noting its lack of typical euchelicerate traits and suggesting that the associated sex-specific glands may have functions in reproduction, with ovigeral glands possibly providing antifungal substances.

Intracardiac bronchogenic cysts (IBCs) are very rare. To date, only a few cases of IBC have been reported in the literature. We report a case of a bronchogenic cyst that arose from the interatrial septum in a 42-year-old man who presented with symptoms of palpitation.

Department of Periodontology, Kyung Hee University College of Dentistry, Kyung Hee University Medical Center, Seoul, Korea.
Article Synopsis
- * In this case study, two patients who had previously undergone the surgery required dental implants, but both had POMCs observed via cone-beam CT, which showed limited bone height for implant placement.
- * An intraoral technique was used for cyst removal and implant installation, resulting in successful integration and healing, with no complications reported over a follow-up period of 4 to 5 years.
Endoscope-assisted treatment for delayed cystic radiation necrosis after stereotactic radiosurgery for metastatic brain tumors: illustrative cases.
J Neurosurg Case Lessons
October 2024
Department of Neurosurgery, Gifu University Graduate School of Medicine, Gifu, Japan.
Article Synopsis
- Cystic radiation necrosis, resulting from radiation therapy for metastatic brain tumors, can require surgical intervention when symptoms arise, making excision of necrotic tissue crucial to avoid recurrence.
- Neuroendoscopic surgery is presented as a minimally invasive technique that allows for effective treatment of these cystic formations by accessing deep brain lesions without extensive procedures.
- In two patient cases, this method successfully removed radiation necrotic tissue, leading to rapid cyst shrinkage and resolution of symptoms, demonstrating the effectiveness of endoscopic surgery for this condition.
Cystic cardiac myxoma: a rare variant of cardiac myxoma in a woman with acute stroke.

Department of Pathology, All India Institute of Medical Sciences, New Delhi, 110029, India.
Article Synopsis
- Cardiac myxomas are the most common benign tumors of the heart, typically appearing as oval masses on the interatrial septum and can cause embolic episodes that require urgent treatment.
- In a case study, a middle-aged woman experienced an acute ischemic stroke and was found to have a complex cystic mass in her left atrium, which was initially difficult to diagnose due to overlapping imaging characteristics with other conditions.
- Surgical removal of the cystic mass was performed to confirm it as a cardiac myxoma and to prevent serious complications like stroke and hemodynamic issues, marking it as a rare case of this tumor variant.
