"Perifollicular rim sign" in an enlarged ovary-an additional non-contrast CT finding in ovarian torsion.

PURPOSE: To look for the presence of "perifollicular rim sign" on non-contrast CT in surgically proven cases of ovarian or adnexal torsion. METHODS: A retrospective analysis of abdominopelvic non-contrast CT examinations in surgically proven cases of ovarian or adnexal torsion was conducted seeking the presence of "perifollicular rim sign" in torsed ovaries. "Perifollicular rim sign" was defined as a complete ring of perifollicular hyperdensity around ovarian follicles with an attenuation value of > 50 HU and thickness > 1-2 mm. A positive sign was equated to the presence of perifollicular hemorrhage. Pre-operative non-contrast CT was available in 7 out of the 39 ovarian or adnexal torsions included in our study. RESULTS: "Perifollicular rim sign" was present in 5 out of the 7 ovarian torsions on pre-operative non-contrast CT. MRI correlation was available in one patient. Ovarian enlargement (>4 cm) was present in all 7 cases. CONCLUSION: In an appropriate clinical setting, presence of "perifollicular rim sign" in an enlarged ovary on non-contrast CT examination can be considered a useful additional sign for ovarian torsion.

Acute Urinary Retention Due to Incarcerated Uterus With Adenomyosis: A Case Report.

Acute urinary retention caused by uterine incarceration due to adenomyosis is a rare phenomenon with limited documented cases. This report details the case of a 38-year-old female with acute urinary retention. A pelvic MRI revealed an enlarged retroverted uterus with a mass on the posterior left of the myometrium, indicative of adenomyosis. The size and anatomical location of the mass suggested uterine incarceration with direct pressure on the urinary bladder neck, leading to urinary retention. The patient underwent total abdominal hysterectomy, bilateral salpingectomy, and adhesiolysis. Subsequent follow-ups at one and three months post-surgery showed the resolution of urinary symptoms, underscoring the importance of considering adenomyosis as a potential cause of urinary retention in women with lower urinary tract symptoms. Timely recognition and appropriate intervention are crucial for mitigating complications and improving outcomes in these patients, as illustrated in this case.

Myocarditis following COVID-19 mRNA (mRNA-1273) vaccination.

In this case report, we presented a case of myocarditis as a rare complication that developed after Covid mRNA-1273 vaccine. Cases of post-vaccine myocarditis usually progress with mild symptoms. However, it should be a situation that healthcare workers should keep in mind, that myocarditis may develop after vaccination.
