Painless Mass

Background: Superficial myofibroblastoma (SMF) is a very rare benign mesenchymal tumor in the female lower genital tract. Only 46 cases have been reported in the English language literature, among which only 7 cases arose in the vulva. Sometimes SMF histologically mimics aggressive angiomyxoma (AA) in which massive myxoid change in stroma is characteristic. We herein report a case of vulvar SMF with prominent myxoid stroma and review the literature with the emphasis on the differential diagnosis of SMF and AA. Case presentation: a 37-year-old woman presented with a painless mass in the vulva. Magnetic resonance imaging (MRI) showed a well-circumscribed 7 cm mass in the subcutis of the vulva. The tumor was resected. Histopathologically, the tumor was characterized by sparsely populated spindle-shaped cells in the fibromyxoid stroma. Thin-walled blood vessels were detected. Mitoses or pleomorphism was not found. Tumor cells were positive for vimentin, ER, PgR, and desmin. Some cells were positive for alpha-SMA and CD34. All cells were negative for S100 protein. Conclusions: because SMF and AA show different clinical prognoses, distinguishing SMF from AA is important. However, SMF may share many common histological features with AA: superficial localization (above fascia), sharp borderline from adjacent tissue, expansive growth pattern; a specific vascular pattern will lead to an accurate diagnosis of SMF. Familiarization with the histological characteristics of the two entities will help to make a prognostic prediction.

Abstract Background Mature presacral (retrorectal) teratoma is very rare. We report a case in which a mature retrorectal teratoma in an adult was successfully treated with laparoscopic surgery. Case presentation A 44-year-old woman was diagnosed with a presacral tumor during a physical examination. Endoscopic ultrasonography (EUS) revealed a multilocular cystic lesion; the lesion was on the left side of the posterior rectum and measured approximately 30 mm in diameter on both contrast-enhanced pelvic computed tomography (CT) and magnetic resonance imaging (MRI). The presumptive diagnosis was tailgut cyst. However, the histopathological diagnosis after laparoscopic resection was mature teratoma. It is still difficult to preoperatively diagnose mature retrorectal teratomas. Conclusions Laparoscopic resection of mature retrorectal teratomas is a feasible and promising method that is less invasive and can be adapted without extending the skin incision.

Abstract Background Management of postoperative chylothorax usually consists of nutritional regimens, pharmacological therapies such as octreotide, and surgical therapies such as ligation of thoracic duct, but a clear consensus is yet to be reached. Further, the variation of the thoracic duct makes chylothorax difficult to treat. This report describes a rare case of chylothorax with an aberrant thoracic duct that was successfully treated using focal pleurodesis through interventional radiology (IVR). Case presentation The patient was a 52-year-old man with chylothorax after a thoracoscopic oesophagectomy for oesophageal cancer. With conventional therapy, such as thoracostomy tube, octreotide or fibrogammin, a decrease in the amount of chyle was not achieved. Therefore, we performed lymphangiography and pleurodesis through IVR. The patient appeared to have an aberrant thoracic duct, as revealed by magnetic resonance imaging (MRI); however, after focal pleurodesis, the leak of chyle was diminished, and the patient was discharged 66 days after admission. Conclusions Chylothorax remains a difficult complication. Focal pleurodesis through IVR can be one of the options to treat chylothorax.

Background Isolated body lateropulsion is a possible predominant manifestation of medulla oblongata infarction, and can occur without vestibular and cerebellar symptoms. However, it is relatively rare and challenging to diagnose. Case presentation A 67-year-old woman was admitted to the Harris International Peace Hospital complaining mainly of instability when standing and walking for the previous 8 hours. Based on the neural localization and multiple head magnetic resonance imaging (MRI) examinations, a diagnosis of cerebral infarction (vertebrobasilar system) was made. Consequently, the patient was managed using therapy aimed at preventing platelet aggregation, lowering plasma lipids, stabilizing plaques, protecting mitochondria, and improving circulation and brain function. The patient’s gait improved and she was discharged after 14 days because she was able to walk unaided. The patient was followed up for 6 months and had no noticeable undesirable side effects or signs of neurological deficits. Conclusion The possibility of lateral medulla oblongata infarction should be considered when patients present with isolated body lateropulsion, without other signs or symptoms of brainstem damage.

Spinal Cavernomas

Case presentation: A 10-year-old male patient was admitted due to posterior cervicalgia, vomiting and progressive generalized weakness. Physical examination showed difficulty in ambulation and tetraparesis. Magnetic resonance imaging (MRI) of the cervical medulla enhanced by the contrast agent, gadolinium, showed a poorly contrasted mass with a hemorrhagic center. We undertook a posterior cervicotomy (C1-C3). Post-operative evolution was satisfactory with complete regression of the deficits 90 days after surgery. Control MRI at intervals of 1 and 4 years confirmed absence of the tumor. Discussion: Cavernomas are vascular malformations, consisting of coarsely dilated vascular channels and coated by a single layer of endothelial cells, devoid of endothelium and myothelium. They represent only 5-12% of all vascular pathologies of the medulla, with only 10% affecting the pediatric population. There are only thirty cases of pediatric intramedullary spinal cavernomas in the literature, with predominance among males (2.1:1). Thoracic and cervical spinal cavernomas consist in 55% and 45% of the cases, respectively. In six cases (20%) cavernomatous lesions were associated with synchronic intracranial cavernoma. Among the reported cases, only one had poor evolution after surgery, whereas six patients persisted with prior symptoms. Conclusion: Spinal intramedullary cavernomas are rare entities, especially in the pediatric population, and are treated with surgery which improves prior neurologic deficits, besides preventing rebleeding

Background: Holospinal epidural abscess (HEA) is a rare pathological entity with significant morbidity and mortality rates. Here, we present a 74-year-old male with HEA treated with focal skip laminectomies and catheter irrigation. Case Description: A 74-year-old male presented with fever, neck/back pain, and slight weakness in his legs bilaterally (4/5). The patient underwent a magnetic resonance imaging (MRI) of the entire spine showing an epidural collection extending from C5-C6 to the L4-L5 levels. Laboratory studies revealed a leukocytosis and an elevated C-reaction protein level. Blood cultures were positive for methicillin-sensitive Staphylococcus aureus. The patient underwent skip laminectomies at C6 and C7; T2, T3, T5, T6, T8, T9, T10, and T12; and L3, L4, and L5 with catheter irrigation between these levels; this minimized the risk of postoperative kyphosis and instability. His postoperative course was uneventful. Other surgical approaches to HEA described in literature include laminectomy, focal laminectomies, and skip laminectomies. Conclusion: In this case of a holospinal HEA, skip laminectomies and catheter irrigation avoided neurological deterioration and delayed spinal instability in a 74-year-old male.

Abstract Background Lipomas are often small tumors and rarely reach a size larger than 2 cm. Vulvar lipoma is a rare tumor localization, and only a few cases have been reported. It is important to distinguish lipomas from other vulvar masses like liposarcomas, Nuck canal cyst, Bartholin’s cyst, and inguinal hernias. Case presentation We report on a case of a 43-year-old woman who presented with a giant left vulvar mass and discuss the magnetic resonance imaging (MRI) results. Conclusions MRI is useful in evaluating vulvar lipomas and differentiating them from other vulvar pathologies.

Objectives: To discuss the presentation and management of infants with arhinia or congenital absence of the nose. Methods: This case report describes an infant with arhinia that was diagnosed prenatally. In addition to a discussion of the case, a review of the literature was completed to define appropriate postnatal work-up and management. Results: The patient is a term male infant, diagnosed with arhinia on ultrasound and magnetic resonance imaging (MRI) performed at 21-weeks gestational age. Upon birth, the patient was subsequently intubated, followed by tracheostomy due to complete nasal obstruction. Through a genetics evaluation, the patient was found to be heterozygous for the SMCHD1 gene, with hypomethylation at the D4Z4 locus. Plans for reconstruction will be based on future imaging and the development of any nasal patency, however, the patient’s family plans to utilize a prosthetic nose until the patient is older. Conclusion: Arhinia is a rare condition causing respiratory distress in the neonatal period. While stabilization of the airway is the first priority, further management is not clearly defined given the rarity of the malformation. This case discusses stabilization of the airway with a review of treatment and reconstructive options.

Abstract Background Meningiomas typically manifest on magnetic resonance imaging (MRI) as iso- to hypointense on T1-weighted imaging and iso- to hyperintense on T2-weighted imaging. After contrast administration, they usually homogeneously enhance and exhibit a visible dural tail. Meningiomas with atypical findings may be misdiagnosed. Case presentation We report a 50-year-old female patient with a pathologically diagnosed fibrous meningioma (World Health Organization grade I) that exhibited ring enhancement on MRI. Conclusions Meningiomas may rarely present with ring enhancement on MRI. The natural history and mechanisms of cystic degeneration and enhancement in the various types of meningioma require further study.

Background and Importance: Hydatid cyst is endemic in India, with different clinical presentations according to the site of involvement in the body. However, its occurrence in the brain without the involvement of other body parts is rare. Case Presentation: An eight-year-old female child presented with right-sided limb weakness and slurring of speech. The diagnosis of primary brain hydatid cyst was made with Magnetic Resonance Imaging (MRI) of the brain. The cyst was removed completely, resulting in improved post-operative slurring of speech and limb weakness. Conclusion: In countries where hydatid disease is endemic, brain hydatidosis should on top of the differential diagnoses for intracerebral cystic lesions and managed as per hydatid protocol until proved otherwise. This approach is critical to prevent rupture and dissemination.

Abstract Background Intraspinal hematoma is a rare complication of acupuncture. A few cases of subdural hematoma or epidural hematoma have been reported, with most of them in a fusiform shape, making the hematomas easy to identify on magnetic resonance imaging (MRI) scans. Case presentation A 49-year-old man presented with back pain that radiated into his lower limb that had appeared during acupuncture of his back. After admission, MRI was performed and indicated an L5/S1 intraspinal mass that had an oval shape, resembling an intraspinal cyst. The patient underwent surgery to remove the mass, which was confirmed to be a hematoma. Conclusion Intraspinal hematomas appear with various intensity signals and shapes on MRI, making its differential diagnosis difficult. A carefully medical history review (to determine if the pain derives from a puncture-type treatment or an injury) and surgical exploration may be helpful for identifying this condition.
