Revealing an Uncommon Presentation of Chiari I Malformation With Diverse Craniovertebral Anomalies in the Absence of Syringomyelia and Atlanto-Occipital Subluxation: A Case Report.

A Chiari I malformation is a frequently encountered anomaly of the posterior fossa, occurring in a notable percentage of the population. It often coexists with various other craniovertebral junction abnormalities, albeit less frequently with Klippel-Feil syndrome. Interestingly, the majority of individuals with Chiari I malformation do not exhibit any symptoms. We present a rare case of a 25-year-old male with chronic neck and occipital pain, along with progressive weakness and sensory disturbances in all four limbs, urinary urgency, and elevated left shoulder. Examination unveiled spasticity, weakness, and brisk reflexes. On extensive radiological evaluation (X-ray, CT, and MRI), findings revealed various anomalies in the craniovertebral junction, including complete atlanto-occipital assimilation, basilar invagination, and platybasia. Furthermore, cervical segmentation abnormalities indicative of Klippel-Feil syndrome were observed, along with Sprengel's deformity. MRI confirmed Chiari I malformation with tonsillar herniation and myelomalacia, as well as compression at the cervico-medullary junction. This patient underwent a surgical procedure that included transoral odontoidectomy combined with occipito-cervical fixation, after which a good clinical response was observed. It emphasizes the necessity of radiological imaging for the diagnosis of Chiari and other associated abnormalities in the craniovertebral junction.

A Case of Lymphangioma of the Calf Region: Imaging Spectrum With Histopathological Correlation.

Lymphangioma, also known as cystic hygroma are benign malformations arising from abnormal development of the lymphatic system. Most often these lesions are found in the pediatric population, having a predilection for the neck/axilla, and are less common in extremities. Symptoms can vary based on size and location. Treatment is not usually indicated until they start impacting life due to deformity or symptoms such as pain, paraesthesia, etc. Here, we report a case report of lymphangioma located in the calf region of the right lower limb presenting in adult age.

Chondrosarcoma of Iliac Bone Imaging Spectrum With Histopathological Correlation: A Case Report.

Chondrosarcoma is a rare form of carcinoma that originates in the cells of cartilage, the flexible tissue that cushions the joints and gives structure to various parts of the body. This malignant tumour primarily affects adults and is most commonly found in the bones of the arms, legs, pelvis, and ribs. The severity and prognosis of chondrosarcoma can vary widely depending on factors such as tumour size, location, and grade. We are reporting a case of an 83-year-old male patient who presented with swelling over the left hip joint. A mass was detected on radiograph and ultrasound that was further characterized using contrast-enhanced CT and MRI. Imaging findings suggested chondrosarcoma. The patient was diagnosed on histopathological examination.

Budd Chiari Syndrome: A Case Report on Classic Imaging Findings With Successful Intervention.

Budd Chiari syndrome is an unusual vascular disease involving the hepatic vasculature and has significant mortality and morbidity if not treated early. Ultrasonography (USG), Doppler, computed tomography (CT), and magnetic resonance imaging (MRI) have classical imaging findings that can help make a reliable and quick diagnosis. Intervention radiology plays an important role in the treatment of these patients, helping avoid various complications and proper patient management. We are presenting a case report with classical imaging spectrum and highlighting successful intervention with hepatic vein stenting.

The Diagnosis and Treatment of Rasmussen's Encephalitis: A Case Report.

Rasmussen's encephalitis is a very rare type of chronic inflammatory disease of the brain. We report a case of a nine-year-old male patient who presented with seizures and cognitive impairment for six years. An MRI of the brain revealed significant cerebral hemiatrophy. The patient was on immunoglobulin therapy. We also engage in a review of the existing literature on Rasmussen's encephalitis.

Rasmussen's Aneurysm: A Rare Case.

Rasmussen's aneurysm is a very uncommon condition occurring in post-pulmonary tuberculosis patients. We are presenting a case of a young male patient with the chief complaints of hemoptysis, breathlessness on exertion, cough with expectoration and fever, and weight loss. A thorough radiological examination revealed multiple cavitary lesions, bronchiectasis, tree-in-bud appearance and pulmonary nodules, and areas of air-spaced opacities, indicating a likely diagnosis of post-primary pulmonary tuberculosis with stages of active infection and healed infection. The post-contrast study revealed a well-defined dilated vascular channel arising from a branch of the right pulmonary artery indicating pseudo-aneurysm formation, i.e., Rasmussen's aneurysm, within a large cavity in the right middle lobe. The patient underwent emergency trans-arterial embolization successfully and he was stable postoperatively.

A Unique Case of Unicornuate Uterus With a Non-communicating Rudimentary Horn and Hematometra.

Congenital uterine anomalies are a rare type of malformation involving female genitalia caused by abnormal development of the Mullerian duct system. Patients having an obstructive type of uterine anomalies are very much likely to develop obstetric and gynecological complications usually at the age of menarche or later in the course of life. In this case report, we present a case of a young female patient having severe dysmenorrhea which is caused by obstructive hematometra in the rudimentary horn which is not communicating with the uterine cavity. Ultrasonography (USG) was used to make a differential diagnosis of a probable congenital abnormality, which was subsequently validated by magnetic resonance imaging (MRI), which revealed a uterine cavity having a single cornu on the left side seen to be connecting with the cervix and a dilated rudimentary horn on the right side. The patient underwent the excision of the rudimentary horn laparoscopically. This case emphasizes the importance of identifying patients having anomalies involving the uterus to provide appropriate treatment to the patient and to prevent adverse outcomes for her reproductive potential.
