Grass Awn

SummaryA two-year-old female Lucerne Hound was presented with a one-week history of signs of progressive neck pain, inappetence, apathy, and an elevated rectal temperature. Findings of magnetic resonance imaging (MRI) were consistent with a foreign body abscess in the epidural space at the level of the first and second cervical vertebrae. A leftsided dorso-lateral atlantoaxial approach was performed, revealing an epidural abscess containing a grass awn. The clinical signs resolved within three days of surgery and the dog made a full recovery. This case report shows that grass awns can migrate to the atlantoaxial region in dogs and MRI findings lead to a suspicion of caudo-cranial migration within the spinal canal.

Background: Cutis Verticis Gyrata (CVG) is a rare skin disease caused by overgrowth of the scalp, presenting as cerebriform folds and wrinkles. CVG can be classified into two forms: primary (essential and non-essential) and secondary. The primary non-essential form is often associated with neurological and ophthalmological abnormalities, while the primary essential form occurs without associated comorbidities. Discussion: We report on a rare case of primary essential CVG with a 4-year history of normal-colored scalp skin mass in the parietal-occipital region without symptom in a 34-year-old male patient, retrospectively summarizing his pathological and Computer Tomography (CT) and magnetic resonance imaging (MRI) findings. The major clinical observations on the CT and MR sectional images include a thickened dermis and excessive growth of the scalp, forming the characteristic scalp folds. With the help of CT and MRI Three-dimensional (3D) reconstruction techniques, the characteristic skin changes could be displayed intuitively, providing more evidence for a diagnosis of CVG. At the 5-year followup, there were no obvious changes in the lesion. Conclusion: Based on our observations, we propose that not all patients with primary essential CVG need surgical intervention, and continuous clinical observation should be an appropriate therapy for those in stable condition.

An 11-year-old male Rough collie was submitted with paraparesis, but did not respond to medical treatment. Clinical signs worsened and the dog displayed paralysis, inability to stand and loss of voluntary bladder control, whereupon magnetic resonance imaging (MRI) was performed. No significant abnormalities were identified from MRI, blood tests, cerebrospinal fluid tests or radiography. After MRI, the dog developed dyspnoea and died. Autopsy and subsequent histopathological examination led to a diagnosis of degenerative myelopathy.

Ectopic Pregnancies

Background. Retroperitoneal ectopic pregnancy is extremely rare. This unusual location represents a great challenge for clinicians due to the difficulties of diagnosis and high risk of life-threatening complications. Case Report. We report the case of a spontaneous early pregnancy of undetermined location in a patient with a history of previous laparoscopic surgery. Diagnosis steps using clinical examination, ultrasound, and magnetic resonance imaging led to the localization of the pregnancy, in the left side of the para-aortic region, in the retroperitoneal space. Conclusion. Retroperitoneal ectopic pregnancy is an uncommon entity with rather complex pathogenesis. Clinicians should carefully interpret clinical signs, biological findings, and imaging features and be aware of unusual locations such as the retroperitoneum for ectopic pregnancies. Early diagnosis and appropriate management strategy are conditio sine qua non for successful treatment outcomes.

Abstract A 23-year-old pregnant woman presented with sudden diplopia, ataxia, hemiparesis, and headache secondary to a brain stem hemorrhage. Magnetic resonance imaging (MRI) revealed a hematoma associated with a probable cavernous hemangioma of the rostral brain stem. In this report, we discuss the MRI findings leading to the preoperative diagnosis, as well as the surgical techniques involved in the successful resection.

Wrist glomus tumours are extremely rare. We report a case of an unusually large wrist glomus tumour with atypical presentation. Magnetic resonance imaging (MRI) findings correlated well to those previously described for digital glomus tumours. This rare differential should be considered when evaluating lesions around the wrist.

Histopathological Results

Lymphoma with hepatic involvement can present with three morphological patterns: diffuse infiltrative, nodular, and mixed infiltrative–nodular. However, lymphoma with periportal infiltrative hepatic involvement is rare. There have been a few reports of cases with this type of hepatic involvement including ultrasound or computed tomography (CT) findings. In this case report, we present CT, magnetic resonance imaging (MRI), and diffusion-weighted MRI findings together with the histopathological results for a patient with periportal hepatic lymphoma presenting with obstructive jaundice.

Myofibroblastoma of the breast (MFB) is a very rare benign stromal tumor. In recent years, increase in mammographic screenings has resulted in increased diagnosis of MFB. Most cases are old males and postmenopausal women. MFB may be confused as malignant, clinically, morphologically, or by imaging. Immunohistochemistry is essential for final diagnosis in these cases. We report a case of a pathologically diagnosed MFB in an 80-year-old male patient who had coexisting prostate cancer and describe its imaging characteristics, especially magnetic resonance imaging (MRI). In this paper, histopathological and MRI findings of the MFB were discussed.

Background Isolated posterior spinal (element) tuberculosis (TB) is uncommon compared to classical anterior spinal or para-discal TB. Here, we report magnetic resonance imaging (MRI) findings of posterior spinal TB in 19 patients without involvement of the vertebral body and intervertebral disc. Purpose To evaluate the MRI findings in isolated posterior spinal (element) TB. Material and Methods Clinical and MRI data of 19 patients of isolated posterior spinal TB were retrospectively evaluated. Results Of the 19 patients, group A comprised 4 (21%) patients with rapid onset lower limb weakness and pyramidal signs while group B comprised 15 (79%) patients without any neurological deficit. Lumbar vertebrae commonly affected 9 (47.4%) patients followed by dorsal vertebrae in 8 (42.1%) patients and cervical vertebrae in 2 (10.5%) patients. The pedicle was most commonly involved in 12 (63.2%) patients followed by the lamina in 11 (58%) patients, and spinous process and facet joint in 6 (31.6%) patients each. Extra-spinal inflammation/pyomyositis/paraspinal abscess was found in 13 (68.4%) patients followed by epidural abscess 3 (15.8%) patients and both extra spinal inflammation and epidural abscess in 3 (15.8%) patients (15.8%). Compressive cord myelopathy was observed in 4 (21%) patients, where three patients underwent emergency decompression laminectomy and the remaining 16 patients were treated conservatively with anti-tubercular therapy. Conclusion Initial diagnosis of isolated posterior element TB is challenging and requires a high index of suspicion. Early diagnosis of isolated posterior spinal TB is important as early treatment may be beneficial and decreases patient morbidity.

A 4-year-old, male Jack Russell terrier was presented for a 6-month history of progressive right hemiparesis with episodic cervical hyperesthesia. The neurological examination showed a right-sided, upper motoneuron syndrome and partial Horner’s syndrome. Two magnetic resonance imaging (MRI) examinations were performed 3 months apart and revealed a persistent cervical intramedullary hematoma. A dorsal myelotomy was performed. A subacute hematoma was confirmed histologically without underlying lesions. Eighteen months later, the dog’s clinical signs were minimal. Two MRI examinations were performed 2 weeks and 5 months after surgery and revealed regressing signal abnormalities at the surgical site, consistent with a surgical scar.

Mri Characteristics

We present the fetal MRI characteristics of exencephaly, a rare malformation of the cranium. The fetus was initially misdiagnosed as anencephaly at 14 weeks of estimated gestational age (EGA) and later mislabeled as acrania at 20 weeks of EGA by ultrasound. A confirmatory magnetic resonance imaging (MRI) at 29 weeks of EGA demonstrated findings consistent with exencephaly, which was confirmed after birth. To our knowledge, no full fetal MRI characteristics have been described. We hope to use this case to review the key MRI findings in differentiating exencephaly from other cranial vault defects and to help early diagnosis of exencephaly as the appropriate use of correct nomenclature allows better research while giving parents the most accurate and appropriate counseling.
