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.

Benign Phyllodes Tumor of Axillary Tail USG and Elastography Evaluation with Histopathological Correlation.

The axillary tail, also known as spencer's tail or axillary process, is a continuation of tissue from the upper lateral quadrant of the breast that travels into the axilla through a foramen of Langer in the deep fascia. Axillary inflammation or lump is a typical clinical symptom that necessitates imaging evaluation. Since the axilla consists of lymph nodes as well as nonlymphatic tissue such as accessory breast tissue, skin, fat, muscles, nerves, and blood vessels, it has a wide variety of differential diagnoses. The radiologists should be well acquainted with axillary anatomy and imaging aspects of various axillary lesions. Here, we present a 35-year-old female with a right axillary lump which was suggestive of benign tumor on ultrasonography and was proven to be benign phyllodes tumor on histopathology.

Imaging Spectrum of Severe Urinary Tract Infection Complications Presenting as a Seminal Vesicle Abscess, Prostatic Abscess, and Renal Abscess in Uncontrolled Diabetes Mellitus: A Case Report.

Urinary tract infections are more common and severe, and they carry worse outcomes for patients with type 2 diabetes mellitus. The infections are typically caused by resistant pathogens, leading to many complications. Various impairments in the immune system, poor metabolic control, and incomplete bladder emptying due to autonomic neuropathy may all contribute to the enhanced risk of urinary tract infections in these patients. We present an imaging spectrum of a severe urinary tract infection presenting as renal, prostatic, and seminal vesicle abscesses in a patient with uncontrolled diabetes mellitus.

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.

Liver Tuberculosis Presenting As Fever of Unknown Origin: A Case Report and Imaging Spectrum With a Review of Literature.

Hepatic tuberculosis is not commonly seen, and it can be easily missed unless there is strong suspicion. It presents clinically with non-specific symptoms like pain in the upper right abdomen, tenderness, mild fever, sweating at night, losing weight, feeling tired, and a lump in the abdomen. We are reporting a case of a 41-year-old female who presented with an intermittent history of fever and right hypochondriac pain for 10 years. Ultrasound and contrast-enhanced computed tomography (CECT) scans of the patient revealed a mass lesion with classical imaging findings of tuberculosis. Subsequently, a biopsy was conducted, confirming the presence of liver tuberculosis.

An Aberrant Case of Pheochromocytoma in a Young Adult Presenting With Secondary Hypertension: A Case Report With Review of the Literature.

Pheochromocytoma (PCC) is a rare neuroendocrine catecholamine-secreting tumour of the adrenal gland. It originates from the chromaffin cells found within the adrenal medulla or the extra-adrenal paraganglia. We present a case report of a 24-year-old female who presented with hypertension, headache, palpitations, chest pain and blurry vision. On ultrasound evaluation, a right suprarenal mass was noted, which was further evaluated using contrast-enhanced computed tomography (CT). Based on our imaging findings, the patient was diagnosed with a case of right-sided pheochromocytoma. The patient was operated on, and our diagnosis was confirmed with histopathological examination.

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.

Primary Testicular Non-Hodgkin's Lymphoma With Bilateral Adrenal Metastasis: A Rare Presentation.

Primary testicular lymphoma is the common testicular neoplasm in patients aged more than 65 years. It accounts for a small number of cases of adult testicular malignancies. Though the metastasis to bone marrow, liver, and central nervous system are well known, metastasis to adrenal glands is a very rare entity. It can be mistaken as a germ cell tumor or a dual malignancy. To rule out other causes, a multidisciplinary approach is required. Here, we present a rare case of primary testicular Non-Hodgkin's lymphoma with bilateral adrenal metastasis.

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.

An Aberrant Case of Large Submandibular Gland Sialolith With Obstructive Sialadenitis in a Young Female.

Sialolithiasis is a major cause of salivary gland dysfunction. Submandibular sialolithiasis with obstructive sialadenitis is a relatively uncommon condition. Submandibular gland sialolithiasis with obstructive sialadenitis accounts for about 2% of all cases of sialadenitis. We are reporting a case of a 20-year-old female who presented with acute-onset swelling in the right submandibular region. The submandibular gland had a large calculus with pericalcular abscess development, which was clearly visible on pre- and post-contrast computed tomography. Subsequently, surgical excision of the lesion was performed, and calculus was removed.

Adenomatoid Tumor of Epididymis Associated with Tubular Ectasia of Rete Testis: Sonographic Evaluation.

Paratesticular tumors are a relatively rare group of mesenchymal tumors, accounting for 7%-10% of all intrascrotal tumors. Adenomatoid tumor of the epididymis is the most common epididymal tumor. It is difficult to distinguish intra- versus paratesticular tumors and to know the nature of the lesion (benign versus malignant) on clinical examination since they may have similar presentation; therefore, ultrasound examination of these lesions is required to demonstrate its extratesticular location and also to suggest its benign nature. Elastography can further help in characterizing the lesion by evaluating the stiffness of the tumor. Here, we present a case of adenomatoid tumor of the left epididymis with tubular ectasia of the rete testis.

An Aberrant Seminoma as a Complication in an Undescended Testis: A Case Report and Review of Literature.

Testicular germ cell tumors are testicular neoplasms in young and middle-aged men. Undescended testis dramatically increases the risk of testicular germ cell tumors. We report the case of a 33-year-old male who complained of swelling and pain in his lower abdomen. The patient also had an undescended left testis. An intrabdominal mass was detected on ultrasound that was further characterized using contrast-enhanced CT. Imaging findings suggested testicular germ cell tumor, developing as a complication in the undescended testis. The patient was operated and the diagnosis was confirmed on histopathological examination.

Chondrosarcoma of Sternal Origin: A Rare Case.

Chondrosarcoma of sternal origin is extremely rare. Here, we present the case of a 59-year-old male who presented with gradually increasing swelling and pain over the left sternoclavicular joint which was diagnosed as chondrosarcoma of sternal origin. We also present a review of the relevant literature.

An Aberrant Case of Foreign Body Granuloma in the Left Forearm Due to an Impacted Piece of Glass Bangle.

Foreign body granuloma is an inflammatory tissue reaction around retained foreign bodies after penetrating trauma. The granulomatous reaction is a natural mechanism of the body to heal wounds by restricting the damage done by a pathological agent and containing the pathological agent to the wound site only. Here we present a classic case of a foreign body granuloma on the dorsal aspect of the forearm. This case was evaluated radiologically on high-frequency ultrasound and X-ray imagining and was operated on afterward. A piece of broken glass bangle was found inside the granuloma.

An Aberrant Case of Sacrococcygeal Teratoma in a Female Infant Born of Twin Pregnancy.

Sacrococcygeal teratoma (SCT) is an uncommon infantile tumor. It has a female preponderance with malignant variants being more common in males. These usually manifest as palpable masses over the sacral region in infancy which may or may not be associated with neural tube defects. An initial radiological investigation is warranted to analyze the extent and components of the mass to guide an approach for surgical excision. We present a classic case of an SCT in a female infant born as a twin. This mass was evaluated radiologically by X-ray and ultrasound followed by histopathological correlation. This is a case of Altman Type-I lesion and was confirmed as a mature teratoma on histopathological examination.

A Rare Case of Congenital Plunging Ranulas: Diagnosis With Intraoral and Extraoral Ultrasound and Magnetic Resonance Imaging.

Ranulas are cystic lesions located in the floor of the mouth. These are "pseudocysts" and are developed due to an obstruction in the sublingual gland. Congenital variants of plunging ranulas are very rare. Here, we report a case of an eight-year-old male child presenting with congenital swelling with an intraoral component as well as extension to the submandibular gland region. The swelling was painless and gradually growing in size.

Radiological Evaluation of a Rare Case of Rib Caries and Cold Abscess in a Young Male Patient With Miliary Tuberculosis: A Case Report With Review of Literature.

Rib caries with a cold abscess is a rare presentation of tuberculosis (TB) and is tricky to diagnose. It is rarer in young patients, especially in conjunction with active miliary TB. We present one such case of a 23-year-old male patient who presented with swelling over the left lower chest. Rib caries and cold abscess were initially detected by ultrasonography and elastography. The rib involvement and the extent of the cold abscess were further evaluated on a computed tomography scan, which also showed active pulmonary miliary TB. The patient was treated by aspiration of the cold abscess and anti-tuberculosis therapy. The fact that the patient had no history of diabetes, alcoholism, human immunodeficiency virus infection, or immunodeficiency disorder increases the rarity of this case. This case highlights the role of imaging in diagnosing rib caries, cold abscess, and miliary TB.

Antenatal Ultrasonographic Diagnosis of a Constellation of Alobar Holoprosencephaly, Ethmocephaly, and Hydronephrosis in a Case of Early-Onset Intrauterine Growth Retardation: A Case Report.

Alobar holoprosencephaly is a congenital malformation that results from failure of the forebrain/prosencephalon to divide into right and left halves. Despite the literature on the genetic and chromosomal abnormalities associated with this condition, information on additional causes and explanations for variability in phenotypic expressivity are lacking. We report a case of early-onset intrauterine growth retardation with alobar holoprosencephaly, ethmocephaly, and hydronephrosis diagnosed on antenatal ultrasonography in a 27-year-old primigravida with no known risk factors or family history. The combination of holoprosencephaly with associated midline facial anomalies and the genitourinary abnormality, in this case, constitutes a rare phenotypic presentation. This case emphasizes the importance of antenatal ultrasonography in the early detection of lethal anomalies like alobar holoprosencephaly. The pregnancy was safely terminated in accordance with the mother's decision.

Rare presentation of autosomal dominant polycystic kidney disease in horseshoe kidney ultrasound evaluation: a case report.

Horseshoe kidney is a renal fusion anomaly during embryogenesis and adult polycystic kidney disease is a hereditary disorder which is transmitted in autosomal dominant pattern. Polycystic and horseshoe kidney are two separate disease entities, only about 20 cases of polycystic kidney disease in horseshoe kidney disease have been described in the literature, with an incidence ranging from 1 in 134 000 to 1 in 8 000 000 live births. We are presenting ultrasound findings of a patient who was incidentally diagnosed with polycystic horseshoe kidney on routine screening.

Ileal Lipoma as a Leading Point of Ileocolic Intussusception in Adult Patient: Ultrasonography and CT Evaluation.

Intussusception in adults is an unusual finding and is commonly associated with benign or malignant mass as the leading point. A preoperative diagnosis on imaging is helpful in diagnosing intussusception along with pathology causing it and aids in further management. We present a case of ileocolic intussusception with lipoma as the lead point: classic ultrasonography and CT imaging findings are described with its postoperative confirmation.
