The anatomical structure of the temporal bone is quite complex. There are a great number of anatomical variations that are often confused with temporal bone pathologies, especially fractures. It is important that radiologists and surgeons be able to recognize such variations.

Background & objectives: This study aimed to assess chest computed tomography (CT) scans and laboratory parameters of patients with Crimean-Congo hemorrhagic fever (CCHF) and compare results between survivors and non-survivors. Methods: Patients diagnosed with CCHF between July 2012 and July 2021 were examined retrospectively. Patient data, thorax CT findings, laboratory results, and demographic characteristics were evaluated. Survivors and nonsurvivors were compared for ground-glass opacity (GGO), pleural effusion, atelectasis, lung consolidation, pulmonary nodules, bronchiectasis, pericardial effusion, and enlarged mediastinal lymph nodes. Laboratory findings and respiratory complaints were recorded regarding survival status. Results: A total of 112 patients were included, with a mean age of 54.2 years and 56.3% male predominance. The most common CT findings were GGO (46.3%), pleural effusion (40%), and atelectasis (36.3%). GGO, pleural effusion, atelectasis, lung consolidation, and pericardial effusion were more frequent in non-survivors than survivors (p<0.05). Non-survivors demonstrated significantly altered laboratory parameters including elevated WBC counts (p<0.01), reduced platelet counts (p<0.001), decreased fibrinogen (p<0.01), and prolonged coagulation times (PT and aPTT, both p<0.001). Pleural effusion and GGO showed significantly higher mortality risk (11.23-fold and 5.89-fold adjusted, respectively). Interpretation & conclusion: GGO, lung consolidation, pleural effusion, pericardial effusion, and atelectasis may serve as poor prognostic indicators, necessitating close monitoring for patients with these potentially life-threatening findings.

Gastric teratomas are rare intra-abdominal tumors. They are frequently seen in the neonatal period. A palpable mass is the most common clinical sign. Although radiologic imaging plays a role in diagnosis, in most cases the final diagnosis is made by histopathologic examination. In this report, we present a newborn male patient diagnosed with immature gastric teratoma. A male infant was referred to the clinic due to bloating and a palpable abdominal mass. Ultrasonography revealed a complex solid cystic mass in the abdominal and pelvic region. Magnetic resonance imaging was recommended. MRI revealed a multilocular, multiseptated, complex lesion. Given the radiologic findings, a gastric teratoma was suspected. The patient underwent surgery. On histopathologic examination, an immature grade 3 teratoma was diagnosed. Gastric teratomas are extremely rare tumors and must be considered in the differential diagnosis of abdominal masses during the neonatal and infant period.

Polycystic ovary syndrome is associated with complex endocrine and metabolic disturbances that may influence brain structure. This study aimed to evaluate
