A Huge Hemorrhagic Epidermoid Cyst of the Perineum with Hypoechoic Semisolid Ultrasonographic Feature Mimicking Scar Endometriosis

Epidermoid cysts are small, solitary, and slow-growing lesions that rarely appear in the perineum and mostly arise because of trauma. This study examined a huge perineal epidermoid cyst that slowly grew over eight years in a premenopausal woman. Ultrasonography showed that the hemorrhage in the cyst was a semisolid hypoechoic mass, which mimicked endometrioma, and was tentatively diagnosed as scar endometriosis in the perineum after vaginal delivery. This case study highlights the importance of wide surgical excision and histopathologic diagnosis, even with typical ultrasonography and surgical findings.

Evaluation of the snowing-like ultrasonographic features of intraosseous jaw pathologies

Aim of the study: Ultrasonographic examination of intraosseous jaw pathologies may reveal interesting incidental, mobile hyperechoic particles (“snowflakes”) in anechoic areas. Purpose of this study is to explain and discuss this snowing-like ultrasonographic feature of intraosseous jaw pathologies. Material and methods: This study included 113 patients admitted to our clinic for examination: 43 (38.05%) males and 70 (61.9%) females with a mean age of 34.9 ± 17.2 years (range: 6–72 years). A total of 120 intraosseous lesions were evaluated prior to surgery using ultrasonography; these included non-neoplastic, odontogenic, and non-odontogenic lesions. Results: In total, 5 (4.1%) of the 120 lesions exhibited snowing-like feature on ultrasonography, including 2 (1.6% of total) of 3 incisive canal cysts, 2 (1.6% of total) of 7 dentigerous cysts, and 1 (0.8% of total) of 19 odontogenic keratocysts. Conclusions: Snowflakes evident on ultrasonography of intraosseous jaw lesions may be specific to certain pathologies. Future studies correlating radiologic and pathologic features of intraosseous jaw lesions should focus on ultrasonographic snowing-like appearance in different types of lesions and explore why they occur.

Follicular neoplasm of the thyroid: can clinical, ultrasonographical and cytological factors be used to predict carcinoma and determine extent of surgery

Background: The optimal management of cytologically indeterminate thyroid nodules in follicular neoplasm is controversial. We examined the prevalence of malignancy within cytologically indeterminate follicular thyroid lesions in an attempt to predict malignancy based on clinical, sonographic and cytologic features.Methods: Retrospective study was done in between April 2017 to July 2019 of 46 patients having a diagnosis of follicular neoplasm on fine needle aspiration cytology.Results: A total of 46 patients (8 men, 38 women; mean age 47 year) with indeterminate cytology underwent thyroidectomy and had histopathological diagnoses. The prevalence of malignancy in patients was 34.7%. The size of nodules and ultrasonographic feature were significant predictor of malignancy with p value <0.05.Conclusions: Author can predict malignancy in follicular neoplasm of thyroid with indeterminate nodule by using clinical and sonographic feature for the best compromise between the risk of missing carcinomas and the need for reducing unnecessary surgical procedures and cost benefit of the patients.

INTRAVENTRICULAR HEMORRHAGE IN UTERO

The authors report three cases of unexplained prenatal intraventricular haemorrhage (IVH) in three term infants. In the first two cases the suspected diagnosis of prenatal IVH was made a few hours after delivery, in accordance with the ultrasonographic feature of clots in the ventricles, whereas in the third case prenatal ultrasonography was suggestive of hydrocephalus with intraventricular clots.
