Idiopathic granulomatous mastitis (IGM) is a rare inflammatory disease of the breast, which is benign but potentially morbid. Mammographic and sonographic findings have been well characterized, but magnetic resonance imaging (MRI) findings have been less thoroughly documented. The objective of this study was to demonstrate characteristic findings for IGM and its mimics via a retrospective review.

Breast MRI examinations performed at Sir Ganga Ram Hospital in New Delhi, India between 2014 and 2019 were retrospectively reviewed to identify cases in which a pattern suggestive of granulomatous mastitis was seen. Cases of known malignancy were excluded. Any available breast pathology results were then obtained, and cases with presumptive or definitive diagnoses were compiled for analysis.

Overall, cases identified with characteristic imaging findings and confirmed diagnosis included seven cases of IGM, four cases of invasive ductal carcinoma, two cases of tuberculous mastitis, one case of non- tuberculous infectious mastitis, one case of foreign body mastitis, and one case of eosinophilc mastitis. One case of IGM with masses rather than of non-mass enhancement was also identified.

In our review, cases with clustered ring enhancement were found to have inflammatory, idiopathic, infectious and malignant etiologies. While, these etiologies can only be reliably differentiated on pathology, familiarity with the pattern and an awareness of the differential may lead to decreased morbidity due to delays in diagnosis.

Urethral recurrence (UR) clinically manifests as a penile mass or a bloody or purulent penile discharge at a median of 13 months after surgery. And on imaging studies, it characteristically appears as a focal intraluminal mass, urethral wall thickening, or an infiltrating mass arising from the urethra. We, herein, present an unusual case of UR manifesting as a large cyst in the penile root 4 years after radical cystectomy with urinary diversion for muscle-invasive bladder cancer. Further, a complex cystic mass developed in the same location 2 years after the excision of the cystic UR. This case shows that the imaging spectrum of UR after radical cystectomy may be wider and may include cystic and complex patterns.

Spinal dermoid cysts are benign tumors that result from congenital or acquired ectodermal inclusions. Long segment intramedullary involvement of the spinal cord is exceedingly rare, and there are only a handful of case reports found in the literature.

A 30-year-old female presented with a 3-month history of myelopathy characterized by progressive quadriparesis and urinary incontinence. Magnetic resonance imaging revealed multifocal heterogeneous intramedullary masses extending from C2 to T4 and at T12-L1 with similar intensity lesions seen within the central cord from T5 to T11 level. Following tumor decompression, she showed significant improvement in neurological function 1 month later. The histopathological examination confirmed the diagnosis of a multifocal intramedullary dermoid cyst.

Partial surgical extirpation is a reasonable treatment for long segment intramedullary dermoid cysts, particularly when the tumor capsule is adherent to critical adjacent neural tissues.

Spontaneous intracranial hypotension (SIH) is caused by spontaneous cerebrospinal fluid (CSF) leaks that can be treated in most cases with an epidural blood patch (EBP). However, some patients, who develop severe brain sagging, can neurologically deteriorate, and in occasional instances, which become comatose. Here, with the presentation of two cases, and a review of the literature, we have set guidelines for diagnosing SIH along with recommendations for its management.

We reviewed two cases of SIH. Both patients became comatose due to a CSF leak associated with a tear in the spinal dura diagnosed on myelo-CT studies. As targeted EBP failed to achieve sustained improvement, direct operative repair of the dural tears was warranted (video presentation).

After reviewing two cases of SIH and the literature, we developed an algorithm for the diagnosis and management of SIH. To avoid deterioration to a comatose status, we recommend the early performance of myelo- CT studies to identify the location of the dural leak, followed by early dural repair.

Spinal teratomas are rare in adults. The clinical findings are nonspecific, reflecting only in the intramedullary location of these lesions. The potential differential diagnosis for intramedullary spinal teratomas include schwannomas, dermoids, epidermoids, and neurofibromas.

A 25-year-old male presented with RLE weakness (iliopsoas/quadriceps [4/5], and extensor hallucis longus/dorsiflexor [0/5]) and urinary incontinence. As the contrast, MR showed a heterogeneous intramedullary lesion with well-defined edges located at the T12-L1 level, the patient underwent a focal laminectomy for gross total tumor excision. Pathologically, it proved to be a mature teratoma.

Teratomas should be considered among the differential diagnostic considerations for intramedullary spinal cord lesions. Although gross total resection is preferred, these lesions have a low recurrence rate, and therefore, partial removal is also valid, where lesions are densely adherent to adjacent neural structures.

Mini-open thoracoscopic-assisted thoracotomy (MOTA) has been introduced to mitigate disadvantages of conventional open anterior or conventional posterior only thoracoscopic procedures. Here, we evaluated the results of utilizing the MOTA technique to perform anterior decompression/fusion for 22 traumatic thoracic fractures.

There were 22 patients with unstable thoracic burst fractures (TBF) who underwent surgery utilizing the MOTA thoracotomy technique. Multiple variables were studied including; the neurological status of the patient preoperatively/postoperatively, the level and type of fracture, associated injuries, operative time, estimated blood loss, chest tube drainage (intercostal drainage), length of hospital stay (LOS), and complication rate.

In 22 patients (averaging 35.5 years of age), T9 and T12 vertebral fractures were most frequently encountered. There were 20 patients who had single level and 2 patients who had two-level fractures warranting corpectomies. Average operating time and blood loss for single-level corpectomy were 91.5 ± 14.5 min and 311 ml and 150 ± 18.6 min and 550 ml for two levels, respectively. Mean hospital stay was 5 days. About 95.45% of cases showed fusion at latest follow-up. Average preoperative kyphotic angle corrected from 34.2 ± 3.5° to 20.5 ± 1.0° postoperatively with an average correction of 41.1% and correction loss of 2.4%.

We concluded that utilization of the MOTA technique was safe and effective for providing decompression/fusion of traumatic TBF.

Meningiomas are the most frequent benign head tumors, although spontaneous hemorrhage is a rare form of presentation of such lesions. Of all possible bleeding locations associated with them, the subdural space is one of the most uncommon, with very few cases reported worldwide.

A middle-aged woman presented with progressively worsening left-sided headache, initiated 2 weeks before, with no other complaints, denying any previous head trauma. Head computed tomography revealed a subacute left hemisphere subdural hematoma and left frontal, suggestive of meningioma on magnetic resonance imaging. Surgical treatment was performed with hematoma evacuation and lesion removal. Neuropathology showed a transitional meningioma with signs of hemorrhage. After surgery, no neurological deficits were registered, and headache abated.

As we could not identify any other cause for the subacute subdural hematoma, hemorrhage from the meningioma was the most probable cause, and thus, we decided to remove it along with clot evacuation. Based on neuropathological findings, we propose an alternative mechanism for this spontaneous hemorrhage from the meningioma, involving the place where the periphery of the lesion insertion, the dura mater as the origin of the hemorrhage. Knowledge of this association could help define the best treatment in such cases.

Meningiomas presenting with acute subdural hematomas are extremely rare. To the best of our knowledge, only 45 cases have been reported to date. We report on a case of a meningioma mimicking an acute subdural hematoma as well as a thorough literature review.

A 67-year-old man with no history of trauma was referred to our hospital with sudden onset of decreased level of consciousness and left hemiplegia. Computed tomography revealed an acute convexity subdural hematoma. Emergency surgery to remove the hematoma was performed. The hematoma was found to exist in the extra-axial space and the attached dura mater and pia mater remained intact. Pathological examination revealed a transitional meningioma, the World Health Organization Grade 1. Detailed medical history taken postoperatively revealed that a convexity meningioma had been diagnosed incidentally at another facility 1 year earlier.

Acute subdural hematomas due to meningiomas are rare, and establishing the cause is challenging. Prompt and precise diagnosis of such entities may afford patients a better prognosis.
