- Background
This study aimed to evaluate ovarian reserve in patients with unilateral endometrioma by exploring correlations between serum anti-Müllerian hormone (AMH) levels and imaging markers derived from ultrasonography and magnetic resonance imaging (MRI).
Methods
We conducted a retrospective study of 146 female patients diagnosed with unilateral endometrioma at a single tertiary hospital between 2015 and 2023. Ovarian size was measured using ultrasonography and MRI, and various absolute and relative indicators were calculated. Serum AMH levels and inflammatory markers were assessed, and statistical analyses were performed to examine correlations between AMH levels and imaging markers.
Results
The participants’ mean age and AMH level were 32.01±5.99 years and 3.54±3.24 ng/mL, respectively. Serum AMH levels were significantly negatively correlated with age and body mass index. Among ultrasonographic parameters, only the maximum diameter of the healthy ovary showed a significant positive correlation with AMH levels. Among MRI-derived parameters, the maximum diameter, mean diameter, and volume of the healthy ovary exhibited significant positive correlations with AMH, whereas the relative volume of the affected ovary showed no significant correlation with AMH. These findings suggest that the healthy ovary plays a crucial role in maintaining ovarian reserve.
Conclusions
In women with unilateral endometrioma, the size and volume of the healthy ovary are significantly associated with serum AMH levels. This information is useful for accurately assessing ovarian reserve. These findings highlight the importance of considering the healthy ovary in treatment planning and counseling for women with unilateral endometrioma.

- Spinal subarachnoid hematoma (SSAH) following lumbar puncture (LP) in patients without coagulopathy is exceedingly rare, but can lead to severe neurologic complications, such as paraplegia. Although LP has been identified as a cause of SSAH in certain cases, its rarity underscores the need for a prompt diagnosis. Here, we present the case of a young patient who developed SSAH after LP and presented with headache and back pain. The patient was diagnosed accurately and rapidly using magnetic resonance imaging and was successfully managed with conservative treatment.

- Squamous cell carcinoma (SCC) of the pancreas is very rare. No reports have described SCC accompanied by intraductal papillary mucinous neoplasm (IPMN) of the pancreas. This report presents the first known case of SCC with IPMN of the pancreas in a 71-year-old man, with a focus on radiologic findings. Here, the imaging features of SCC with IPMN of the pancreas were similar to those of IPMN of the pancreas with high-risk stigmata features.

Abstract

Contrast-induced encephalopathy (CIE) following cerebral angiography has similar clinical presentations to ischemic complications of cerebral angiography. Neurologic deficits in CIE are mostly transient, but those caused by acute cerebral infarction (ACI) as ischemic complications of cerebral angiography may be permanent. Therefore, distinguishing CIE from ACI is important. Diffusion restriction on magnetic resonance imaging (MRI) implies ACI, while hyperintensity on diffusion weighted imaging (DWI) without correlation on the apparent diffusion coefficient (ADC) map implies CIE. We reported a rare case of CIE with diffusion restriction on MRI following cerebral angiography that mimicked MRI findings of ACI. The mechanism of this phenomenon remains unknown and requires further investigation.

Objectives Identification of axillary metastases in breast cancer is important for staging disease and planning treatment, but current techniques are associated with a number of adverse events. This report evaluates the diagnostic accuracy of superparamagnetic iron oxide (SPIO)-enhanced magnetic resonance imaging (MRI) techniques for identification of axillary metastases in breast cancer patients.
Methods We performed a meta-analysis of previous studies that compared SPIO enhanced MRI with histological diagnosis after surgery or biopsy. We searched PubMed, Ovid, Springer Link, and Cochrane library to identify studies reporting data for SPIO enhanced MRI for detection of axillary lymph node metastases in breast cancer until December 2013. The following keywords were used: “magnetic resonance imaging AND axilla” and “superparamagnetic iron oxide AND axilla”. Eligible studies were those that compared SPIO enhanced MRI with histological diagnosis. Sensitivity and specificity were calculated for every study; summary receiver operating characteristic and subgroup analyses were done. Study quality and heterogeneity were also assessed.
Results There were 7 publications that met the criteria for inclusion in our meta-analysis. SROC curve analysis for per patient data showed an overall sensitivity of 0.83 (95% Confidence interval (CI): 0.75–0.89) and overall specificity of 0.97 (95% CI: 0.94–0.98). Overall weighted area under the curve was 0.9563.
Conclusions SPIO enhanced MRI showed a trend toward high diagnostic accuracy in detection of lymph node metastases for breast cancer. So, when the breast cancer patients has axillary metastases histologically, SPIO enhanced MRI may be effective diagnostic imaging modality for axillary metastases.
