This prospective multicentric study aiming to determine the incidence of complications (malignant transformation, torsion or rupture) during conservative management of adnexal masses was performed in two Portuguese tertiary referral hospitals. It included ≥18-year-old, non-pregnant patients with asymptomatic adnexal masses (associated IOTA ADNEX risk of malignancy < 10%) sonographically diagnosed between January 2016 and December 2020. Conservative patient management consisted of serial clinical and ultrasound assessment up to 60 months of follow-up, spontaneous resolution of the formation or surgical excision (median follow-up: 17.8; range 9–48 months). From the 573 masses monitored (328 premenopausal and 245 postmenopausal adnexal masses), no complications were observed in 99.5%. The annual lesion growth rates and increases in morphological complexity were similar in the premenopausal and postmenopausal patients. Spontaneous resolution, evidenced in 16.4% of the patients, was more common in the premenopausal group (p < 0.05). Surgical intervention was performed in 18.4% of the cases; one borderline and one invasive FIGO IA stage cancer were diagnosed. There was an isolated case of ovary torsion (0.17%). These data support conservative management as a safe option for sonographically benign, stable and asymptomatic adnexal masses before and after menopause and highlight the need for expedite treatment of symptomatic or increased-morphological-complexity lesions.

Belly dancer dyskinesia (BDD) is a rare movement disorder characterized by involuntary, repetitive contractions of the abdominal wall. Pregnancy-associated BDD is exceptionally uncommon, and recurrence in subsequent pregnancies has rarely been reported. We describe the case of a 29-year-old woman in her first pregnancy who developed involuntary abdominal movements at 16 weeks. Her medical history included hypertension and multiple uterine fibroids. Neurological assessment, laboratory investigations, and spinal magnetic resonance imaging were unremarkable, and a clinical diagnosis of BDD was established. Symptoms persisted throughout pregnancy and resolved immediately after delivery. Two years later, during a second pregnancy, similar movements recurred at 15 weeks, again resolving completely after delivery. Recurrence during two consecutive pregnancies suggests a pregnancy-related trigger for BDD, and complete postpartum resolution highlights the self-limiting course of this benign condition.
