MRI Insights in Chiari Malformation Type 1 and Variations With Hydrosyringomyelia.

Chiari malformation (CM) type 1 is a complex neurological disorder characterized by the displacement of the cerebellar tonsils into the upper spinal canal. Hydrosyringomyelia (HSM), which frequently coexists with this condition, presents diagnostic and treatment problems due to its broad spectrum of symptoms. There are various forms of CMs, with CM type 1 (CM1) being the most common type. Magnetic resonance imaging (MRI) is the best imaging technique to properly identify and diagnose CM1 and HSM. Important imaging findings include downward displacement of the cerebellar tonsils across the foramen magnum, the appearance of the syrinx in the spinal cord, and the alteration of the flow dynamics of the cerebrospinal fluid. This study was conducted at Datta Meghe Medical College, Nagpur, and Government Medical College & Super Speciality Hospital, Nagpur, India. It focuses on the diagnostic use of MRI in CM1 and its variations associated with HSM. Individuals who are asymptomatic may not need any treatment; however, those who are symptomatic or have HSM may require surgical decompression and restoration of the flow. We discuss the findings of MRI of six cases of CM1 and its variants with HSM and search for possible underlying causes. We conclude that magnetic resonance imaging is an imaging modality for the identification and evaluation of CM1 in cases of HSM.

Challenging Diagnosis and Management of an Ovarian Cyst Torsion in a Postmenopausal Woman: A Case Report.

Ovarian masses are rare in the postmenopausal age group, and ovarian torsion is a gynecological emergency. We present a case report of a 63-year-old postmenopausal woman who presented a massive abdominal mass with pain that gradually increased during the previous 12 months. A contrast-enhanced computed tomography scan of the abdomen and pelvis suggested a 16.6 cm × 14 cm × 13 cm originating from the right ovary. Total abdominal hysterectomy, bilateral salphingo-oophorectomy, and partial omentectomy were performed in an emergency as the patient's symptoms worsened. A massive cyst was visualized from the right ovary, which had undergone a torsion of three turns. Histopathological analysis revealed a serous cystadenoma. The twisted ovarian cyst typically manifests as an acute abdomen, although there are cases where this presentation can cause a significant delay in diagnosis. Therefore, high clinical suspicion is often necessary to prevent morbidity and mortality.
