Inadvertent placement of the urinary catheter into the ureter can cause several complications. We describe a rare complication during cystogram due to unrecognized inadvertently placed urinary catheter in ureter, resulting in a life-threatening situation. A 47-year-old multiparous female underwent total laparoscopic hysterectomy for adenomyosis. During early postoperative period, she developed vesicovaginal fistula and transvaginal repair of fistula was done. During filling cystography done at 2 weeks, she developed right loin pain and urosepsis...

Preoperative localization of breast malignancies using traditional ultrasound and digital techniques can be challenging, particularly after neoadjuvant chemotherapy when the target is not conspicuous. The purpose of this paper is to pictorially present nontraditional techniques that have been helpful in preoperative localization before surgery. We will discuss techniques for breast lesion localization using computed tomography (CT) and magnetic resonance imaging (MRI) as well as axillary lymph node localization using tomosynthesis, CT, and MRI...

Motor neuron diseases (MNDs) are a debilitating subset of diseases, which result in progressive neuronal destruction and eventual loss of voluntary muscular function. These entities are often challenging to distinguish and accurately diagnose given overlapping clinical pictures and overall rarity. This group of diseases has a high morbidity and mortality rate overall and delineating each type of disease can help guide appropriate clinical management and improve quality of life for patients. Of all MNDs, amyotrophic lateral sclerosis (ALS) is by far the most common comprising 80%-90% of cases...

Malleus fracture is a rare condition. Usually, the handle of the malleus is involved, and we do not find reports in the literature of this condition in the bilateral presentation. It is present as sudden conductive hearing loss commonly after digital manipulation of the external auditory canal. The diagnosis is based principally on clinical examination by otomicroscopy and audiometry. Cone-beam computed tomography emerging as a powerful tool in the field of otolaryngology, especially for explorations of paranasal sinuses and temporal bone, due to imaging with a high resolution and few artifacts with lower dose radiation in comparison with multislice computed tomography...

REVIEW
Alexander T Kessler, Alok A Bhatt
The salivary glands are small structures in the head and neck, but can give rise to a wide variety of benign and malignant pathology. When this occurs, patients may present with palpable swelling, although it is quite common that they are asymptomatic and a salivary gland mass was discovered as an incidental finding on imaging performed for another reason. It is, therefore, critical that radiologists pay careful attention to the salivary glands and have working knowledge of the key differentiating features of the most common neoplastic and nonneoplastic etiologies of salivary gland masses...

REVIEW
Alexander T Kessler, Alok A Bhatt
The major and minor salivary glands of the head and neck are important structures that contribute to many of the normal physiologic processes of the aerodigestive tract. The major salivary glands are routinely included within the field of view of standard neuroimaging, and although easily identifiable, salivary pathology is relatively rare and often easy to overlook. Knowledge of the normal and abnormal imaging appearance of the salivary glands is critical for forming useful differential diagnoses, as well as initiating proper clinical workup for what are often incidental findings...

Endoscopic intervention is well validated for the control of upper gastrointestinal bleeding (UGIB). In cases of refractory bleeding, transarterial embolization is a safe and effective alternative. Ethylene vinyl alcohol (EVOH) commonly known as Onyx® is an inherently black liquid embolic approved for use in cerebrovascular arteriovenous malformations and is increasingly used as an embolic agent in multiple peripheral and visceral territories. Onyx® has a uniquely undesirable property of causing black color discoloration when used in peripheral applications adjacent to the skin akin to a "tattoo effect...

Chudley-McCullough syndrome (CMS), an autosomal recessive condition first reported by Chudley et al., in 1997, comprises profound sensorineural hearing loss and specific brain abnormalities. The hearing loss may be congenital or early onset. Brain abnormalities are striking, but despite these brain malformations, individuals with CMS do not present significant neurodevelopmental abnormalities. Recently, the cause of CMS has been shown to be the inactivating mutations in G protein signaling modulator 2. We aimed to present a 36-year-old male who has the characteristic clinical and neuroimaging findings of CMS...

Waardenburg syndrome (WS) is a rare genetic disorder secondary to neural crest cell developmental abnormalities. It is predominantly described as an auditory-pigmentary syndrome with diverse patient presentation, typically involving congenital sensorineural hearing loss and pigmentation abnormalities of the skin, hair, and iris. Other developmental abnormalities that may be associated with this syndrome are Hirschsprung's disease and a myriad of cardiovascular congenital defects. We present a case of a young girl with WS who found to have a persistent left superior vena cava (PLSVC) draining into the coronary sinus...

Laryngocele is a rare entity and can be defined as an abnormal cystic dilatation of saccule of the laryngeal ventricle with communication to the lumen of larynx. Laryngopyocele is a rare complication of laryngocele when it is infected. Patients may present with fever, neck swelling, shortness of breath, and hoarseness. Acute presentation can develop rapidly with alarming symptom, such as stridor, which signifies airway obstruction and warrants immediate treatment and airway protection. Computed tomography and endoscopy are useful in making the diagnosis and delineate the severity of disease...

Calibre-persistent labial artery (CPLA) is a commonly underdiagnosed vascular lesion of the lip. CPLA is an arterial branch that penetrates the submucosal tissue without loss of calibre. Clinical diagnosis is significant as misdiagnosis can lead to profuse haemorrhage following an excisional biopsy or surgical excision. Colour Doppler ultrasonography is a safe and non-invasive diagnostic tool to confirm the diagnosis. Here, we report a case of a 24-year-old man who complained of an asymptomatic pulsating non-progressive nodule on the left side of upper lip initially diagnosed as peripheral angiomatous lesion...

Superficial siderosis is the slow accumulation of hemosiderin on the pial surfaces of the brain and spinal cord. The most common cause of intracranial superficial siderosis is secondary to subarachnoid hemorrhage. Rarely, superficial siderosis can also be caused by tumors. Superficial siderosis presents clinically as hearing loss and gait instability that progressively worsen. The diagnosis is primarily made by magnetic resonance imaging; however, susceptibility-weighted imaging (SWI) and T2* gradient echo (GRE) sequences demonstrate the highest sensitivity in detecting this condition...
