Minimally invasive vaginal approach to the uterovestibular anastomosis for cervicovaginal aplasia: a case series and review of literature.

BACKGROUND: Congenital cervicovaginal agenesis (CVA) with functioning endometrium is an extremely rare mullerian anomaly. Genital tract patency and fertility preservation are the major challenges in cases of CVA. With the advances in surgical techniques, management has shifted from a radical approach-like hysterectomy towards a more conservative approach of uterine conservation. CASE PRESENTATION AND REVIEW OF THE LITERATURE: In the present study, we report our experience in managing four cases of congenital CVA with complete vaginal atresia, which were treated with a simple minimally invasive vaginal approach for UVA without using graft for neovagina creation and studied the long-term anatomic and functional result of uterovestibular anastomosis (UVA) in patients with CVA. A literature review was performed for congenital complete vaginal atresia (≤ 2 cm blind vagina), with a functioning uterus. The experience and results of this 4-year study are in accordance with the prior studies with 97% (33/34) success rate, where vestibular mucosa was used for the UVA. CONCLUSIONS: Findings of this study should encourage more gynaecologists to learn and recreate a complete vaginal approach, as no special surgical equipments are needed. Hysterectomy should only be reserved for cases, where repeated anastomosis attempts fail. This minimally invasive technique should be preferred over canalization procedures and graft, as it is associated with a higher success rate with least complications and recurrence. Conservative end-to-end anastomosis with a completely vaginal approach should be offered as the primary treatment option for CVA with total vaginal atresia.

Sonographic appearance of endometrial osseous metaplasia.

Osseous metaplasia of the endometrium is a rare condition characterized by the presence of mature or immature bone in the endometrium. Most cases present with secondary infertility following an abortion or chronic endometritis. Some patients are asymptomatic, while others have menstrual abnormalities such as menorrhagia or oligomenorrhea. Removal of the bony fragments helps in spontaneous conception. We hereby present two cases of osseous metaplasia of the endometrium with radiological and pathological correlation.

Sonographic Appearance of Testicular Adrenal Rest Tumour in a Patient with Congenital Adrenal Hyperplasia.

BACKGROUND: Testicular adrenal rest tumours (TARTs) are benign testicular masses that are found in inadequately treated patients with congenital adrenal hyperplasia (CAH). Recognizing this association and identifying characteristic ultrasound features of TARTs is important so as to avoid misdiagnosing them as malignancies, which can lead to unnecessary interventions. CASE REPORT: We describe a case of a 9-year-old boy, with a diagnosis of CAH and precocious puberty, who was referred to our department for an ultrasound evaluation of the abdomen and scrotum. On ultrasound, there were well-defined, heterogeneous, predominantly hypoechoic, round-to-oval masses in both testes. Taking into account the presence of CAH and a typical sonographic appearance of bilateral testicular masses, a diagnosis of testicular adrenal rest tumour was made; biopsy was deferred and hormonal treatment was modified. CONCLUSIONS: Prompt diagnosis of testicular adrenal rest tumours is essential, as it only indicates inadequate hormonal control. Moreover, it can prevent unnecessary biopsies and orchidectomies, and can maintain fertility. TARTs have a typical imaging appearance that every radiologist must be aware of.

Atraumatic Main-En-Griffe due to Ulnar Nerve Leprosy.

BACKGROUND: Leprosy is the most common form of treatable peripheral neuropathy. However, in spite of effective chemotherapeutic agents, neuropathy and associated deformities are seldom ameliorated to a significant extent. This necessitates early diagnosis and treatment. Clinical examination of peripheral nerves is highly subjective and inaccurate. Electrophysiological studies are painful and expensive. Ultrasonography circumvents these demerits and has emerged as the preferred modality for probing peripheral nerves. CASE REPORT: We describe a 23-year-old male who presented with weakness and clawing of the medial digits of the right hand (main-en-griffe) and a few skin lesions since eighteen months. The right ulnar nerve was thickened and exquisitely tender on palpation. Ultrasonography revealed an extensive enlargement of the nerve with presence of intraneural color Doppler signals suggestive of acute neuritis. Skin biopsy was consistent with borderline tuberculoid leprosy with type 1 lepra reaction. The patient was started on WHO multidrug therapy for paucibacillary leprosy along with antiinflammatory drugs. Persistence of vascular signals at two months' follow-up has led to continuation of the steroid therapy. The patient is compliant with the treatment and is on monthly follow-up. CONCLUSIONS: In this manuscript, we review multitudinous roles of ultrasonography in examination of peripheral nerves in leprosy. Ultrasonography besides diagnosing enlargement of nerves in leprosy and acute neuritis due to lepra reactions, guides the duration of anti-inflammatory therapy in lepra reactions. Further, it is relatively inexpensive, non-invasive and easily available. All these features make ultrasonography a preferred modality for examination of peripheral nerves.

Enlarged parathyroid glands with variable sonomorphology in a case of tertiary hyperparathyroidism: Sonographic-histopathologic correlation.

The typical sonomorphology of homogeneously hypoechoic texture of an enlarged parathyroid gland (PG) is a reflection of uniform arrangement of the parathormone-producing chief cells. A variable cellular arrangement, hemorrhage, fibrosis, and adipocytes cause heterogeneous appearance. We describe a case of a 32-year-old male, a case of tertiary hyperparathyroidism, with increased serum parathormone levels, hypercalcemia, and enlargement of all four PGs, albeit with differing morphology. The left lower gland had two nodules, namely, superior and inferior. The inferior nodule of the left lower gland had an echogenic core surrounded by a sonolucent rim whereas the superior nodule was homogenously hyoechoic. The left upper gland had an echopattern exactly reverse of the inferior nodule of the left lower PG, i.e., hypoechoic gland surrounded by hyperechoic periphery. The appearance of the right-sided glands was that of the superior nodule of the left lower PG. On histopathology, the hypoechoic areas corresponded to numerous chief cells and congested vessels whereas edema gave rise to an increase in echogenicity. This report exemplifies atypical sonographic appearances of PG and their histopathologic correlation.

Supernumerary testis: Imaging appearance of a rare entity.

Supernumerary testis is a rare congenital anomaly of the testis arising from abnormal division in the genital ridge during the embryogenesis of testis. We describe a case of polyorchidism detected incidentally in a 52-year-old with renal failure.

Sonography of postpartum uterine inversion from acute to chronic stage.

We report the sonographic appearance of postpartum uterine inversion progressing from acute partial to chronic stage after an 8-week interval. The delay in diagnosis was partly due to the patient's stable clinical condition except for minor vaginal discharge and bleeding. The diagnosis of chronic inversion on the follow-up sonographic examination prompted clinicians to undertake surgical repair. Our case shows that the prompt use of sonography during labor and in the peripartum should be sufficient to establish the diagnosis of this serious postpartum complication, which can result in shock or even death. Sonography findings can be considered characteristic and fairly accurate in this condition.

Sonographic diagnosis of inferior mesenteric artery aneurysm and marginal artery of Drummond.

We report the case of a patient in whom sonographic examination revealed an aneurysm of the inferior mesenteric artery with severe proximal stenosis and poststenotic dilatation--the enlargement of the proximal portion of the artery of Drummond. This collateral pathway should be kept in mind when studying bowel ischemia, especially when stenosis is present or when there is occlusion of the superior mesenteric artery.

Scimitar syndrome.

Scimitar syndrome, a rare anomaly of partial pulmonary venous drainage into the hepatic portion of the inferior vena cava, detected in a ten-day-old neonate who presented clinically with respiratory distress and diagnosed on ultrasound of the thorax is being reported here.
