1/17. A giant intracranial mucocele associated with an orbitoethmoidal osteoma. Case report.The authors present a rare case of a giant intracranial mucocele associated with an orbitoethmoidal osteoma in a patient suffering from a generalized convulsive disorder. The broad pedicle of the osteoma had penetrated the cribriform plate and extended intracranially to form a nodular mass in the olfactory groove. The intracranial portion of the osteoma was surrounded by a mucocele. Both the cyst wall and multilayered intracystic septations of the mucocele were indented by layers of the osteoma. Although the extracranial portion adhered to the mucosa of the ethmoidal sinus, there were no signs of sinus obstruction. No direct communication other than the osteoma was identified between the mucocele and the ethmoidal mucosa. The large cerebral defect, which the mucocele occupied, communicated directly with the lateral ventricle without any intervening membranous structures. A frontal craniotomy is recommended for exposure of the lesion and plastic repair of the dural defect.- - - - - - - - - - ranking = 1keywords = giant (Clic here for more details about this article) |
2/17. Intracranial spread of a giant frontal mucocele: case report.A giant mucocele eroded both the anterior and posterior wall of the frontal sinus and infiltrated the dura mater. Its extracranial growth caused a frontal bony prominence. The tumour and part of the dura were resected. A 12 x 6cm defect in the dura was repaired with a freeze-dried patch. A split-thickness bone graft from the right parietal region was used to repair the anterior frontal bony defect. The result one year later was satisfactory. Spiral computed tomography with thr ee-dimensional reconstructions excluded any recurrence of the tumour and showed good integration of bone grafts.- - - - - - - - - - ranking = 1keywords = giant (Clic here for more details about this article) |
3/17. Giant laryngoceles: a cause of upper airway obstruction.Laryngoceles and saccular cysts, which are abnormal dilatations of the laryngeal saccule, are uncommon. The etiology is unknown but is probably related to both congenital and acquired factors. These structures are usually asymptomatic and are incidentally discovered through radiographic studies for unrelated symptoms. We describe two patients with upper airway obstruction, one caused by a giant laryngocele and the other by a large saccular cyst. In the former patient, acute tracheotomy had to be performed. The laryngocele and saccular cyst were removed surgically, which relieved patients' symptoms of upper airway obstruction.- - - - - - - - - - ranking = 0.2keywords = giant (Clic here for more details about this article) |
4/17. Atypical lipomatous tumor of the lip with pleomorphic lipoma-like myxoid area, clinically simulating mucocele.Lipomatous tumor is least common in the oral cavity. We present a case of atypical lipomatous tumor arising in the lower lip of an 81-year-old male. Clinical diagnosis was mucocele. The tumor measured 12 mm in diameter with a round shape. It was solid, firm, myxomatous and translucent with a small yellowish focus in the central portion. Histologically, the tumor was a circumscribed and well-encapsulated mass with prominent myxoid matrix. The central minor portion showed a well-differentiated liposarcoma. In the myxoid area, lipoblasts and large atypical cells with dense chromatin including floret-like giant cells were seen in abundance. Atypical lipomatous tumor may be indistinguishable from pleomorphic lipoma and its distinction from the latter is based on location as well as relative abundance of floret-type giant cells and lipoblasts. According to its abundance in lipoblasts over floret-like cells, pleomorphic lipoma-like area in our case could also be a part of atypical lipomatous tumor. It may be possible to interpret myxoid change in our case as to represent a superficial counterpart of myxoid malignant fibrous histiocytoma-like change reported in the retroperitoneal lesion.- - - - - - - - - - ranking = 0.4keywords = giant (Clic here for more details about this article) |
5/17. Giant frontoethmoid mucocele with intracranial extension: case report.We report the case of a 31-year-old woman who came to us with a giant frontoethmoid mass that had extended into the intracranial region and invaded the left orbit. We removed the lesion in its entirety via a combined intranasal and transcranial approach. We discuss the advantages and disadvantages of different surgical approaches, and we explain why we recommend a combined approach for the type of giant lesion that we encountered.- - - - - - - - - - ranking = 0.4keywords = giant (Clic here for more details about this article) |
6/17. Giant frontal sinus mucocoele with intracranial extension and orbital displacement in an elderly Nigerian.Mucocoele of the frontal sinus presents with initial sign of forehead swelling in about 10% of cases, and cases with huge intracranial extension have been reported to be rare. We present a case of a giant frontal sinus mucocoele with intra-cranial and intra-orbital extensions exerting a mass effect on the anterior cranial fossa in a 78 year old Nigerian female with resultant forehead swelling, proptosis and total blindness of the left eye. diagnosis was made on clinical and radiological basis, and enucleation using coronal flap approach was done. Immediate repair of the resultant frontal bone defect was effected through the use of a curved 0.5mm stainless steel wire fixed in 3 layers across the defective frontal bone over which the soft tissues of the forehead were undermined for primary closure on sound bone. This approach was considered more appropriate than a split rib graft in view of the patient's age. No evidence of recurrence was recorded during a one-year post-surgery follow-up, suggesting that mucocoele, regardless of size can be treated with conservative surgical approach provided all cystic lining and mucocoele are removed.- - - - - - - - - - ranking = 0.2keywords = giant (Clic here for more details about this article) |
7/17. A case of giant appendiceal mucocele.Appendiceal mucocele is a rare clinical condition that causes distension of the appendix lumen with mucus. A seventy-three-year-old female patient presented with complaints of abdominal pain, nausea, and vomiting. Abdominal examination revealed mild tenderness, right lower quadrant pain upon palpation, rebound tenderness and muscular rigidity, and a palpable mass. Abdominal ultrasonography and computed tomography scans demonstrated a cystic lesion in the right iliac fossa, adherent to the cecum, suggesting an abdominal abscess. An emergency operation was performed, during which a diagnosis of a mucocele of the appendix was made. Surgical treatment included appendicectomy, partial resection of the ileum, and resection of the cecum. Histopathologic examination confirmed the operative diagnosis. The role of imaging and clinical approach is emphasized in the treatment of an appendiceal mucocele, especially in emergency settings.- - - - - - - - - - ranking = 0.8keywords = giant (Clic here for more details about this article) |
8/17. An unusual presentation of a giant frontal sinus mucocele manifesting with a subcutaneous forehead mass.INTRODUCTION: To describe the unusual manifestation of a giant frontal sinus mucocele. CLINICAL PICTURE: A 33-year-old female presented with blurring of vision in the left eye, periorbital swelling and a painless forehead mass. There was proptosis, partial ptosis, and an elongated, soft, subcutaneous mass over the left side of the forehead. CT scan showed a mass arising from the frontal sinus with both intraorbital and intracranial extension. TREATMENT: Surgical excision of the mass confirmed the diagnosis of a mucocele. OUTCOME: Postoperatively, the patient was asymptomatic. CONCLUSIONS: A subcutaneous soft-tissue mass may be the presenting complaint of a frontal mucocele. Careful examination of the surrounding skin may suggest the diagnosis of sinus-related disease and thus direct appropriate investigations.- - - - - - - - - - ranking = 1keywords = giant (Clic here for more details about this article) |
9/17. Giant appendiceal mucocele: report of a case and brief review.mucocele of the appendix is a rare lesion, characterized by distension of the lumen due to accumulation of mucoid substance. This disease is often asymptomatic and pre-operative diagnosis is rare. If untreated, one type of mucocele may rupture producing a potentially fatal entity known as pseudomyxoma peritonei. The type of surgical treatment is related to the dimensions and to histology of the mucocele. appendectomy is used for simple mucocele or for cystadenoma. Right hemi-colectomy is recommended for cystadenocarcinoma. In this paper, we report a case of a 51-year-old woman with a mobile, painless mass in the right lower quadrant of abdomen caused by a giant appendiceal mucocele. Imaging showed a large, tubular, cystic structure extending below from the inferior wall of the cecum. Surgery revealed a giant retro-cecal appendix measuring 17 cm in length and 4 cm in diameter. The final pathologic diagnosis was mucocele caused by mucinous cystadenoma.- - - - - - - - - - ranking = 0.4keywords = giant (Clic here for more details about this article) |
10/17. Giant mucocele of the frontal sinus.Giant mucocele of the frontal sinus is a rare pathology of benign entity caused by retention of mucous secretions in the sinus. It may expand and erode the surrounding structures such as bones and cerebral parenchyma. The authors describe a patient with frontal giant mucocele involving the orbit, the ethmoid, and intracranial portion of the dura. The main presenting symptoms were diplopia and proptosis. A computed tomography scan and magnetic resonance imaging were performed to permit differential diagnosis from other pathologies such as ossifying fibroma, fibrous dysplasia, and other neoplasms. A single stage maxillofacial and neurosurgical approach to treatment was taken consisting in the removal of the mucocele and reconstruction of the eroded bones with cranial bone grafts. The dura was repaired with temporalis muscle fascia sealed with fibrin glue. Two years after surgery, the patient shows no recurrence and satisfactory morphologic and functional results.- - - - - - - - - - ranking = 0.2keywords = giant (Clic here for more details about this article) |
