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.

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.

Earlier, the dimensions of the gland were estimated by extracting lacrimal glands from cadavers, later ultrasonography and computed tomography studies were used, but had limited soft tissue differentiation. The aim of this study was to retrospectively evaluate Magnetic Resonance Imaging (MRI) data from normal orbits and determine lacrimal gland dimensions. Methods: five hundred and twelve (512) consecutive MRI brain contrast scans (of 240 females, of 272 males; age range 40±20 years) for non-orbital diseases were evaluated retrospectively. The mean axial length (AL), axial width (AW), coronal length (CL), and coronal width (CW) of each lacrimal gland were measured separately. Results: five hundred and twelve (512) MRI brain contrast scans of 272 men and 240 women, with mean age of 40 ± 20 years were included. Right and left LG dimensions were similar, mean AL (13.2±1.35 mm versus 13.11±1.24 mm), mean AW [3.5±0.99 mm versus 3.3±0.82 mm], mean CL [16.3±2.5 mm versus 16.10±2.4 mm], and mean CW (4.15±0.89 mm versus 4.11±0.85 mm). The AL of both lacrimal glands and the CL and CW of right but not left lacrimal glands were significantly lower in women than in men. Age showed significant correlations with the AL and CL of both LGs. Conclusion: in this study, evaluation of normal morphometric parameters of the lacrimal gland in Indian population was established. LG dimensions are smaller in women than men, as well as correlating with side and age.

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.

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.

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.

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.
