Article Synopsis
  • Atraumatic localized convexity subarachnoid hemorrhage (cSAH) is a rare type of bleeding in the brain that can be caused by issues like internal carotid artery dissection (ICAD), particularly when associated with a condition known as Eagle syndrome, characterized by an elongated styloid process (ESP).
  • A case involving a 47-year-old woman revealed cSAH along with ICAD and an ESP, leading to the diagnosis of Eagle syndrome; despite severe headaches and imaging challenges, the causes were identified and treated conservatively.
  • The findings underscore the importance of thorough investigation in cSAH cases, as recognizing conditions like Eagle syndrome can lead to better patient outcomes and prevent

A 75-year-old woman presented with fatigue and multiple enlarged lymph nodes and was initially suspected of having metastatic cancer of unknown primary origin. Differential diagnoses included carcinomatous meningitis, neurosarcoidosis, and TBM, as suggested by the presence of multiple enhancing cerebral nodules.

A 73-year-old woman who had been followed in our department of gynecology because of ovarian cancer since 2002, was admitted with liver dysfunction and complaining of back pain and light precordial chest pain. The chest radiograph on admission revealed a tumor in her left upper lung field, and chest CT revealed a tumor adjacent to the chest wall and mediastinum. FDG-positron emission tomography (PET) showed abnormal uptake in the tumor and Th6/7, and the subaortic lymph nodes.
