Arterial thoracic outlet syndrome by a commonly overlooked anomaly, the cervical rib: A case report.

Thoracic outlet syndrome (TOS) is a constellation of symptoms that occur due to the compression of neurovascular structures traversing the thoracic outlet. TOS manifests in 3 distinct forms: neurogenic, venous, and arterial. Among these, arterial TOS is the rarest. A 32-year-old man presenting with severe right arm pain was referred for CT angiography. The imaging revealed bilateral cervical ribs, with the right side showing more pronounced development and fusion with the first thoracic rib. At the fusion site of the right cervical rib and the first thoracic rib, a pseudoaneurysm of the right subclavian artery was detected. Additionally, there was evidence of acute thromboembolism in the right brachial artery at the mid-humerus. Arterial thoracic outlet syndrome is a rare form of TOS that can have detrimental consequences due to associated complications. Cross-sectional imaging, such as CT scans and MRI, is the preferred method for diagnosing TOS and identifying its specific form. Physicians are expected to be familiar with the various forms of TOS, the lesions mimicking TOS, and the imaging tools utilized for diagnosis.

Misdiagnosis of rarest subtype of sporadic Creutzfeldt Jakob Disease: a case report.

BACKGROUND: Creutzfeldt-Jakob disease (CJD), is a deadly degenerative condition of the central nervous system marked by rapidly progressive dementia. Magnetic resonance imaging (MRI) abnormalities in the cerebral cortex, basal ganglia, thalamus, and cerebellum could indicate severe acute diseases caused by a variety of factors. Although their MRI patterns may resemble those of CJD, clinical history, additional MRI findings, and laboratory testing are all necessary to provide a reliable difference. Here, we report a misdiagnosed case of probable VV1 subtype of sporadic CJD (sCJD) in which follow-up MRI supported the diagnosis. CASE PRESENTATION: A 41-year-old male patient attended the Neuropsychiatry Department with rapidly progressive dementia, akinetic mutism, and difficulty walking and speaking. His problem began with forgetfulness, disorganized behavior, and disorganized speech 7 months earlier which progressed rapidly and was accompanied by aphasia, apraxia, agnosia, and akinetic mutism in the last 2 months. On neurologic examination, hypertonia, hyperreflexia, frontal ataxia, bradykinesia, gait apraxia, and aphasia were noted. Based on clinical features and rapid symptoms progression the likely diagnosis of CJD was suspected. MRI and electroencephalography (EEG) were advised. MRI revealed features of diffuse cortical injury of both cerebral hemispheres also involving bilateral corpus striatum with evidence of cerebral volume loss. EEG showed lateralized periodic theta slow waves on the right side. According to the CDC's diagnostic criteria for CJD, the diagnosis of probable sCJD was established. Supportive care and symptomatic treatment are provided for the patient. After a 1-month follow up the patient's condition deteriorated significantly. The time-lapse from the first reported symptom to death was about 13 months. CONCLUSION: The need of addressing CJD in patients presenting with rapidly progressive dementia is highlighted in this case report. In the early stages of the disease, interpretation of MRI results might cause diagnostic difficulties; therefore, follow-up MRI is critical in obtaining the correct diagnosis.

Perforated retrocecal appendicitis presenting with lung abscess-A case report.

Retrocecal appendicitis usually presents with atypical signs and symptoms which may lead to delayed diagnosis, perforation and serious complications. Development of a large lung abscess secondary to perforation of retrocecal appendicitis in an adolescent patient is an extremely rare entity and to the best of our knowledge has not been described in literature. We present a 15-year-old boy with complaint of chest pain, cough, fever, vague abdominal pain and raised inflammatory markers who underwent CT examination. On CT, a collection with focal calcification was noted in the right iliac fossa that extended along the right retroperitoneum through the retrocrural space in the right lung base communicating with a cavitary pulmonary lesion with air-fluid level. A diagnosis of perforated retrocecal appendicitis with retroperitoneal and right lung abscesses was made. The patient underwent appendectomy and the entire retroperitoneal and lung abscesses were drained. A lung abscess as a complication of perforated retrocecal appendicitis should be in consideration in septic patients with thoracoabdominal infectious manifestations.

Incidental Left Ventricular Myocardial Hydatid Cyst - A case report.

Hydatid disease is an indolent parasitic infection by a microorganism, echinococcosis granulosis. The disease can infect almost any human organ but is exceedingly rare involving the mediastinum and the heart. It can be lethal if complications occur. CT scan is the modality of choice for the diagnosis of the disease. The coverage of cardiac structures in the abdominal CT scan survey may be helpful for the detection of possible cardio-mediastinal hydatid disease. The authors present a case of hydatid cyst in the left ventricular wall alongside hepatic hydatid cysts. The definitive treatment includes surgery under cardiopulmonary bypass and needs to be treated as soon as it is diagnosed to prevent lethal complications.

Massive inguino-scrotal herniation of urinary bladder in an infant (scrotal cystocele)-case report.

Scrotal cystocele (massive inguino-scrotal herniation of urinary bladder) is an extremely rare event occurring in pediatric population. Authors present a case of a massive herniation of urinary bladder into the scrotum in a 1-year-old male infant who presented with markedly enlarged scrotum. Extremely rare case of massive urinary bladder herniation into scrotum, as we were able to find only one reported case in literature search. Enlarged scrotum in infants can be due to multiple causes in which one of them can be herniation of urinary bladder and it is key to know the contents of hernia sac before any intervention.

Childhood giant omental and mesenteric lipoma.

Omental and mesenteric lipomas are very rare benign lesions of mature adipose tissue. They are well-defined, noninvasive, and encapsulated masses that can be discovered in asymptomatic patients or may cause variable nonspecific symptoms depending on their size and location. The omental and mesenteric lipoma has confusing features in ultrasound; however, computed tomography and magnetic resonance imaging can well characterize and demarcate these lesions. Though few cases of mesenteric and omental lipomas have been reported in the literature, but because of its large size and childhood presentation, the case we present, can be one of the largest childhood omental and mesenteric lipomas ever reported. A 6-year-old girl presented with slowly progressing abdominal distension and repeated dull abdominal pain for last 4 years. Abdominal and pelvic computed tomography examination revealed a huge mesenteric and omental lipoma that was resected surgically without any complications.
